The E-mount is a lens mount designed by Sony for their NEX ("New E-mount eXperience" ) and ILCE series of camcorders and mirrorless cameras . The E-mount supplements Sony's α mount , allowing the company to develop more compact imaging devices while maintaining compatibility with 35mm sensors. E-mount achieves this by:
70-490: A hot shoe is a mounting point on the top of a camera to attach a flash unit and other compatible accessories. It takes the form of an angled metal bracket surrounding a metal contact point which completes an electrical connection between camera and accessory for standard, brand-independent flash synchronization . The hot shoe is a development of the standardised " accessory shoe " or " cold shoe ", with no flash contacts, formerly fitted to cameras to hold accessories such as
140-452: A 120 roll, and twice that number of a 220 film. These correspond to 6x9, 6x7, 6x6, and 6x4.5 respectively (all dimensions in cm). Notable manufacturers of large format and roll film SLR cameras include Bronica , Graflex , Hasselblad , Seagull , Mamiya and Pentax . However, the most common format of SLR cameras has been 35 mm and subsequently the migration to digital SLR cameras, using almost identical sized bodies and sometimes using

A compatible 7-pin variant, which allows battery-less accessories to be powered by the camera's battery were also made, but not widely used. Konica Minolta and Sony Alpha digital SLR cameras are based on Minolta designs and used the same connector, officially named Auto-lock Accessory Shoe , as well up to 2012. Since the electrical protocol remained mostly compatible, TTL and non-TTL adapters exist to adapt ISO-based flashes to iISO hotshoes and vice versa. Sony also used
280-460: A PC terminal, both are typically wired to the same trigger contact in the camera rather than triggered independently as in cameras with electronic triggering circuits. When only the PC terminal is used and nothing is connected to the hotshoe, a flash with high trigger circuit voltages connected to the PC terminal delivers this voltage on the normally unprotected middle contact of the camera's ISO hotshoe. If
350-509: A camera with built-in flash and no hot shoe. The trigger voltages provided by some modern flashes or radio triggers can also be too low to reliably trigger electronic circuits in the camera or receiver. Trigger circuit voltages below ca. 2 to 2.5 volts may exhibit this problem, unless the triggering circuit is specifically designed to work with such low voltages. Older cameras equipped with an electro-mechanical trigger contact may exhibit yet another problem. If they provide both an ISO hotshoe and
420-417: A certain range, providing the convenience of adjusting the scene capture without moving the camera or changing the lens. A prime lens, in contrast, has a fixed focal length. While less flexible, prime lenses often provide superior image quality, are typically lighter, and perform better in low light. Focus involves adjusting the lens elements to sharpen the image of the subject at various distances. The focus
490-475: A circuit between shoe and contact—when it is completed by the camera, the flash fires. In addition to the central contact point, many cameras have additional metal contacts within the "U" of the hot shoe. These are proprietary connectors that allow for more communication between the camera and a "dedicated flash". A dedicated flash can communicate information about its power rating to the camera, set camera settings automatically, transmit color temperature data about
560-478: A combination of multiple mechanical components and principles. These include exposure control, which regulates the amount of light reaching the sensor or film; the lens, which focuses the light; the viewfinder, which allows the user to preview the scene; and the film or sensor, which captures the image. Several types of cameras exist, each suited to specific uses and offering unique capabilities. Single-lens reflex (SLR) cameras provide real-time, exact imaging through
630-454: A commonplace activity. The century also marked the rise of computational photography , using algorithms and AI to enhance image quality. Features like low-light and HDR photography , optical image stabilization, and depth-sensing became common in smartphone cameras. Most cameras capture light from the visible spectrum , while specialized cameras capture other portions of the electromagnetic spectrum , such as infrared . All cameras use
700-521: A critical role as it determines how much of the scene the camera can capture and how large the objects appear. Wide-angle lenses provide a broad view of the scene, while telephoto lenses capture a narrower view but magnify the objects. The focal length also influences the ease of taking clear pictures handheld, with longer lengths making it more challenging to avoid blur from small camera movements. Two primary types of lenses include zoom and prime lenses. A zoom lens allows for changing its focal length within
770-405: A galvanic isolator and could withstand 400 volts DC or AC. The similar Sony flash sync terminal and ISO hotshoe adapters FA-ST1AM and FA-HS1AM also offer galvanic isolation as well, but only up to 60 volts DC or AC. Flash servos and radio triggers, e.g. PocketWizard , can also provide electrical isolation, as trigger and receiver unit are physically separate. The camera is only presented with

Some professional SLRs can be provided with interchangeable finders for eye-level or waist-level focusing, focusing screens , eyecup, data backs, motor-drives for film transportation or external battery packs. In photography, the single-lens reflex camera (SLR) is provided with a mirror to redirect light from the lens to
910-399: A mechanical or electronic shutter, the latter of which is common in smartphone cameras. Electronic shutters either record data from the entire sensor simultaneously (a global shutter) or record the data line by line across the sensor (a rolling shutter). In movie cameras, a rotary shutter opens and closes in sync with the advancement of each frame of film. The duration for which the shutter
980-420: A non-ISO-based 13+1 pin hot shoe, named Mini Advanced Shoe on some of its camcorders. An internal camera circuit connects the center contact and shoe mount to trigger the flash. The magnitude and polarity of the voltage between the contacts on the flash in the open-circuit condition has varied between different flash units; this is of no consequence for a simple electromechanical contact on the camera so long as
1050-407: A pivotal technology in the fields of photography and videography, cameras have played a significant role in the progression of visual arts, media, entertainment, surveillance, and scientific research. The invention of the camera dates back to the 19th century and has since evolved with advancements in technology, leading to a vast array of types and models in the 21st century. Cameras function through
1120-533: A rangefinder, or flash connected by a cable . The dimensions of the hot shoe are defined by the International Organization for Standardization (ISO) in ISO 518:2006. Details such as trigger voltage are not standardised; electrical incompatibilities are still possible between brands. The hot shoe is shaped somewhat like an inverted, squared-off "U" of metal. The matching adapter on the bottom of
1190-409: A short burst of bright light during exposure and is a commonly used artificial light source in photography. Most modern flash systems use a battery-powered high-voltage discharge through a gas-filled tube to generate bright light for a very short time (1/1,000 of a second or less). Many flash units measure the light reflected from the flash to help determine the appropriate duration of the flash. When
1260-429: A small display, offering a wider range of information such as live exposure previews and histograms, albeit at the cost of potential lag and higher battery consumption. Specialized viewfinder systems exist for specific applications, like subminiature cameras for spying or underwater photography . Parallax error , resulting from misalignment between the viewfinder and lens axes, can cause inaccurate representations of
1330-405: A specialized trade in the 1850s, designs and sizes were standardized. The latter half of the century witnessed the advent of dry plates and roll-film , prompting a shift towards smaller and more cost-effective cameras, epitomized by the original Kodak camera, first produced in 1888. This period also saw significant advancements in lens technology and the emergence of color photography, leading to
1400-563: A surge in camera ownership. The first half of the 20th century saw continued miniaturization and the integration of new manufacturing materials. After World War I, Germany took the lead in camera development, spearheading industry consolidation and producing precision-made cameras. The industry saw significant product launches such as the Leica camera and the Contax , which were enabled by advancements in film and lens designs. Additionally, there
1470-777: A variety of other proprietary hotshoes for other digital cameras, including the ISO-based 6-pin Cyber-shot hotshoe, the 16-pin Active Interface Shoe (AIS) and the ISO-based 16-pin Intelligent Accessory Shoe (IAS). Some of their NEX cameras used a proprietary Smart Accessory Terminal (versions 1 and 2). In September 2012, Sony announced a new ISO-based 21+3 pin Multi Interface Shoe for use with their future digital cameras of

#17327809498551540-475: Is adjusted through the focus ring on the lens, which moves the lens elements closer or further from the sensor. Autofocus is a feature included in many lenses, which uses a motor within the lens to adjust the focus quickly and precisely based on the lens's detection of contrast or phase differences. This feature can be enabled or disabled using switches on the lens body. Advanced lenses may include mechanical image stabilization systems that move lens elements or
1610-416: Is adjusted, the opening expands and contracts in increments called f-stops . The smaller the f-stop, the more light is allowed to enter the lens, increasing the exposure. Typically, f-stops range from f / 1.4 to f / 32 in standard increments: 1.4, 2, 2.8, 4, 5.6, 8, 11, 16, 22, and 32. The light entering the camera is halved with each increasing increment. The wider opening at lower f-stops narrows
1680-462: Is an assembly of multiple optical elements, typically made from high-quality glass. Its primary function is to focus light onto a camera's film or digital sensor, thereby producing an image. This process significantly influences image quality, the overall appearance of the photo, and which parts of the scene are brought into focus. A camera lens is constructed from a series of lens elements, small pieces of glass arranged to form an image accurately on
1750-433: Is correctly placed. The photographer then winds the film, either manually or automatically depending on the camera, to position a blank portion of the film in the path of the light. Each time a photo is taken, the film advance mechanism moves the exposed film out of the way, bringing a new, unexposed section of film into position for the next shot. The film must be advanced after each shot to prevent double exposure — where
1820-464: Is dictated by the sensor's size and properties, necessitating storage media such as Compact Flash , Memory Sticks , and SD (Secure Digital) cards . Modern digital cameras typically feature a built-in monitor for immediate image review and adjustments. Digital images are also more readily handled and manipulated by computers, offering a significant advantage in terms of flexibility and post-processing potential over traditional film. A flash provides
1890-487: Is measured using a built-in light meter or exposure meter. Taken through the lens (called TTL metering ), these readings are taken using a panel of light-sensitive semiconductors . They are used to calculate optimal exposure settings. These settings are typically determined automatically as the reading is used by the camera's microprocessor . The reading from the light meter is incorporated with aperture settings, exposure times, and film or sensor sensitivity to calculate
1960-400: Is open is called the shutter speed or exposure time . Typical exposure times can range from one second to 1/1,000 of a second, though longer and shorter durations are not uncommon. In the early stages of photography, exposures were often several minutes long. These long exposure times often resulted in blurry images, as a single object is recorded in multiple places across a single image for
2030-499: Is possible to connect an older high-voltage triggering flash to a camera which can only tolerate 5 or 6 volts through an adaptor containing the necessary voltage protection circuitry, typically using a high power TRIAC . Such adapters drain power from the flash's trigger voltage and therefore often do not need a power supply of their own. In order to avoid dangerous loops when connecting equipment in complex studio setups, better adapters offer voltage protection and galvanic isolation of
2100-465: Is pulled across the film plane during exposure. The focal-plane shutter is typically used in single-lens reflex (SLR) cameras, since covering the film (rather than blocking the light passing through the lens) allows the photographer to view the image through the lens at all times, except during the exposure itself. Covering the film also facilitates removing the lens from a loaded camera, as many SLRs have interchangeable lenses. A digital camera may use
2170-547: Is replaced by the film to make the exposure; they are suitable for static subjects only and are slow to use. The earliest cameras produced in significant numbers were plate cameras , using sensitized glass plates. Light entered a lens mounted on a lens board which was separated from the plate by extendible bellows. There were simple box cameras for glass plates but also single-lens reflex cameras with interchangeable lenses and even for color photography ( Autochrome Lumière ). Many of these cameras had controls to raise, lower, and tilt

2240-526: The Canon Pellix and others with a small periscope such as in the Corfield Periflex series. The large-format camera, taking sheet film, is a direct successor of the early plate cameras and remained in use for high-quality photography and technical, architectural, and industrial photography. There are three common types: the view camera, with its monorail and field camera variants, and
2310-412: The press camera . They have extensible bellows with the lens and shutter mounted on a lens plate at the front. Backs taking roll film and later digital backs are available in addition to the standard dark slide back. These cameras have a wide range of movements allowing very close control of focus and perspective. Composition and focusing are done on view cameras by viewing a ground-glass screen which

In contrast, the film camera industry in the UK, Western Europe, and the USA declined during this period, while manufacturing continued in the USSR, German Democratic Republic, and China, often mimicking Western designs. The 21st century witnessed the mass adoption of digital cameras and significant improvements in sensor technology. A major revolution came with the incorporation of cameras into smartphones, making photography
2520-410: The camera through an aperture, an opening adjusted by overlapping plates called the aperture ring. Typically located in the lens, this opening can be widened or narrowed to alter the amount of light that strikes the film or sensor. The size of the aperture can be set manually, by rotating the lens or adjusting a dial or automatically based on readings from an internal light meter. As the aperture
2590-533: The composition, lighting, and exposure of their shots, enhancing the accuracy of the final image. Viewfinders fall into two primary categories: optical and electronic. Optical viewfinders, commonly found in Single-Lens Reflex (SLR) cameras, use a system of mirrors or prisms to reflect light from the lens to the viewfinder, providing a clear, real-time view of the scene. Electronic viewfinders, typical in mirrorless cameras, project an electronic image onto
2660-511: The contacts. For instance a stereo microphone or electronic viewfinder can be used in the Olympus XZ-1 camera's hot shoe. FotoSpot geotagging satellite positioning units utilize the accessory shoe for mounting to the camera. Camera A camera is an instrument used to capture and store images and videos, either digitally via an electronic image sensor , or chemically via a light-sensitive material such as photographic film . As
2730-422: The degree of magnification expected of the final image. The shutter, along with the aperture, is one of two ways to control the amount of light entering the camera. The shutter determines the duration that the light-sensitive surface is exposed to light. The shutter opens, light enters the camera and exposes the film or sensor to light, and then the shutter closes. There are two types of mechanical shutters:
2800-410: The duration of the exposure. To prevent this, shorter exposure times can be used. Very short exposure times can capture fast-moving action and eliminate motion blur. However, shorter exposure times require more light to produce a properly exposed image, so shortening the exposure time is not always possible. Like aperture settings, exposure times increment in powers of two. The two settings determine

2940-820: The energy is not so high as to damage the contacts. However, with more recent cameras with electronic triggering, excessive or insufficient voltage, or incorrect polarity can cause failure to fire, or damage the camera. The ISO 10330 specification allows for a trigger voltage of 24 volts. Some manufacturers, particularly Canon, ask for no more than 6 volts. Flash units designed for modern cameras use voltages which are safe and effective, but some older flashes have much higher voltages, up to hundreds of volts, which damage electronic triggering circuits. Some use negative DC polarity, or AC. iISO hotshoe contacts are only protected up to ca. 5 volts in some cameras. Minolta documented all their cameras' electronically controlled PC terminals and ISO hot shoes to be protected up to 400 volts. It
3010-528: The evolution of the technology in the 19th century was driven by pioneers like Thomas Wedgwood , Nicéphore Niépce , and Henry Fox Talbot . First using the camera obscura for chemical experiments, they ultimately created cameras specifically for chemical photography, and later reduced the camera's size and optimized lens configurations. The introduction of the daguerreotype process in 1839 facilitated commercial camera manufacturing, with various producers contributing diverse designs. As camera manufacturing became
3080-408: The exposure value (EV), a measure of how much light is recorded during the exposure. There is a direct relationship between the exposure times and aperture settings so that if the exposure time is lengthened one step, but the aperture opening is also narrowed one step, then the amount of light that contacts the film or sensor is the same. In most modern cameras, the amount of light entering the camera
3150-463: The external dimensions are 20.7 mm x 18 mm x 5.1 mm. The spacing between the two "teeth" of the shoe is 12.6 mm. Before the 1970s, many cameras had an "accessory shoe" intended to hold accessories including flashes that connected electrically via a cable , external light meters , special viewfinders , or rangefinders . These earlier accessory shoes were of standard shape and had no electrical contacts; contacts were added to produce
3220-543: The finger pressure was released. The Asahiflex II , released by Japanese company Asahi (Pentax) in 1954, was the world's first SLR camera with an instant return mirror. In the single-lens reflex camera, the photographer sees the scene through the camera lens. This avoids the problem of parallax which occurs when the viewfinder or viewing lens is separated from the taking lens. Single-lens reflex cameras have been made in several formats including sheet film 5x7" and 4x5", roll film 220/120 taking 8,10, 12, or 16 photographs on
3290-556: The flash is attached directly to the camera—typically in a slot at the top of the camera (the flash shoe or hot shoe) or through a cable—activating the shutter on the camera triggers the flash, and the camera's internal light meter can help determine the duration of the flash. Additional flash equipment can include a light diffuser , mount and stand, reflector, soft box , trigger and cord. Accessories for cameras are mainly used for care, protection, special effects, and functions. Large format cameras use special equipment that includes
3360-435: The flash unit slides in from the back of the camera and is sometimes secured by a clamping screw or sliding clamp on the flash. In the center of the "U" is a metal contact point. This is used for standard, brand-independent flash synchronization . Normally the metal of the shoe and the metal of the contact are electrically isolated from each other. To fire the flash, these two pieces are connected together. The flash unit sets up
3430-423: The hot shoe. Canon , Nikon , Olympus , and Pentax use the standard ISO hot shoe with various proprietary electronic extensions. In 2014, camera accessory manufacturer Cactus combined these electronic extensions into a multi-brand hot shoe on their wireless flash transceiver V6 . With multi-brand ISO hot shoe, cameras and flashes from different manufacturers work together. In 1988 Minolta switched to use
3500-438: The image sensor itself to counteract camera shake, especially beneficial in low-light conditions or at slow shutter speeds. Lens hoods, filters, and caps are accessories used alongside a lens to enhance image quality, protect the lens, or achieve specific effects. The camera's viewfinder provides a real-time approximation of what will be captured by the sensor or film. It assists photographers in aligning, focusing, and adjusting
3570-498: The introduction of the affordable Ricohflex III TLR in 1952 to the first 35mm SLR with automatic exposure, the Olympus AutoEye in 1960, new designs and features continuously emerged. Electronics became integral to camera design in the 1970s, evident in models like Polaroid's SX-70 and Canon's AE-1 . Transition to digital photography marked the late 20th century, culminating in digital camera sales surpassing film cameras in

The rapid development of smartphone camera technology in the 21st century has blurred the lines between dedicated cameras and multifunctional devices, profoundly influencing how society creates, shares, and consumes visual content. Beginning with the use of the camera obscura and transitioning to complex photographic cameras,
3710-467: The leaf-type shutter and the focal-plane shutter. The leaf-type uses a circular iris diaphragm maintained under spring tension inside or just behind the lens that rapidly opens and closes when the shutter is released. More commonly, a focal-plane shutter is used. This shutter operates close to the film plane and employs metal plates or cloth curtains with an opening that passes across the light-sensitive surface. The curtains or plates have an opening that
3780-513: The lens forwards or backward to control perspective. Sony NEX The short flange focal distance prohibits the use of an optical viewfinder , as a mirror box mechanism cannot be included in this reduced distance. Therefore all E-mount cameras use an electronic viewfinder . Initially, E-mount was implemented on the Sony α NEX-3 and NEX-5 consumer-targeted devices with APS-C sized sensors. E-mount integration into Sony camcorder products
3850-480: The lens. Large-format and medium-format cameras offer higher image resolution and are often used in professional and artistic photography. Compact cameras, known for their portability and simplicity, are popular in consumer photography. Rangefinder cameras , with separate viewing and imaging systems, were historically widely used in photojournalism. Motion picture cameras are specialized for filming cinematic content, while digital cameras , which became prevalent in
3920-437: The light-sensitive surface. Each element is designed to reduce optical aberrations , or distortions, such as chromatic aberration (a failure of the lens to focus all colors at the same point), vignetting (darkening of image corners), and distortion (bending or warping of the image). The degree of these distortions can vary depending on the subject of the photo. The focal length of the lens, measured in millimeters, plays
3990-403: The low voltage used by the local trigger unit, and the remote receiver unit is designed to tolerate up to 200 volts from its flash port. Slave flash, where the flash from a safe flash unit connected to the camera triggers an unconnected flashgun which, if connected, would present a dangerous voltage, is another way to use a flashgun which cannot be connected to a hot shoe; indeed, it can be used for
4060-429: The optimal exposure. Light meters typically average the light in a scene to 18% middle gray. More advanced cameras are more nuanced in their metering—weighing the center of the frame more heavily (center-weighted metering), considering the differences in light across the image (matrix metering), or allowing the photographer to take a light reading at a specific point within the image (spot metering). A camera lens
4130-407: The photographer's eyebrows accidentally make contact with the middle contact, the electrical shock can cause pain or even injuries. One way camera manufacturers have used to avoid this problem was to use two independent trigger contacts, which, however, could cause flash synchronization problems. Another, as utilized by Minolta in all such cameras supporting a PC terminal, was to add a small switch on
4200-407: The range of focus so the background is blurry while the foreground is in focus. This depth of field increases as the aperture closes. A narrow aperture results in a high depth of field, meaning that objects at many different distances from the camera will appear to be in focus. What is acceptably in focus is determined by the circle of confusion , the photographic technique, the equipment in use and

#17327809498554340-429: The same lens systems. Almost all SLR cameras use a front-surfaced mirror in the optical path to direct the light from the lens via a viewing screen and pentaprism to the eyepiece. At the time of exposure, the mirror is flipped up out of the light path before the shutter opens. Some early cameras experimented with other methods of providing through-the-lens viewing, including the use of a semi-transparent pellicle as in
4410-873: The same section of film is exposed to light twice, resulting in overlapped images. Once all frames on the film roll have been exposed, the film is rewound back into the cartridge, ready to be removed from the camera for developing. In digital cameras, sensors typically comprise Charge-Coupled Devices (CCDs) or Complementary Metal-Oxide-Semiconductor (CMOS) chips, both of which convert incoming light into electrical charges to form digital images. CCD sensors, though power-intensive, are recognized for their excellent light sensitivity and image quality. Conversely, CMOS sensors offer individual pixel readouts, leading to less power consumption and faster frame rates, with their image quality having improved significantly over time. Digital cameras convert light into electronic data that can be directly processed and stored. The volume of data generated
4480-404: The shutter is briefly opened to allow light to pass during the exposure. Loading film into a film camera is a manual process. The film, typically housed in a cartridge, is loaded into a designated slot in the camera. One end of the film strip, the film leader, is manually threaded onto a take-up spool. Once the back of the camera is closed, the film advance lever or knob is used to ensure the film

Accessories which do not connect electrically to the camera can be inserted into hot shoes, without using
4620-402: The subject's position. While negligible with distant subjects, this error becomes prominent with closer ones. Some viewfinders incorporate parallax-compensating devices to mitigate that issue. Image capture in a camera occurs when light strikes a light-sensitive surface: photographic film or a digital sensor . Housed within the camera body, the film or sensor records the light's pattern when

They use either transformers or opto-couplers to transfer a safe trigger impulse from the camera to the flash. They are powered by batteries, as their electronics cannot be powered from the flash. As an example, Minolta offered the PC terminal adapter PCT-100 ( 8825-691 ) for this purpose, which worked as
