The Sony Alpha 99 was announced by Sony on September 12, 2012. It was the flagship Sony DSLR camera and of the Sony Alpha SLT line until late 2016 when it was replaced by the Sony α99 II .
26-413: It features the 24.3MP 35mm full-frame Exmor APS HD CMOS sensor, with the normal sensor range of ISO 100–3200. The selectable sensitivity is up to ISO 25600, which makes this camera able to capture still images in low-light environments. This camera can also combine six images together, to generate a single image with two additional steps of ISO sensitivity. This is also the first Sony Alpha camera to use

78-452: A 300 mm lens on a full-frame camera. The extra "reach", for a given number of pixels, can be helpful in specific areas of photography such as wildlife or sports. Lower size sensors also allow for the use of a wider range of lenses, since some types of optical impurities (specifically vignetting) are most visible around the edge of the lens. By only using the center of the lens, these impurities are not noticed. In practice, this allows for
104-436: A 62° diagonal angle of view, the same as that of a 36 mm lens on a 35 mm film camera. On a full-frame digital camera, the 24 mm lens has the same 84° angle of view as it would on a 35 mm film camera. If the same lens is used on both full-frame and cropped formats, and the subject distance is adjusted to have the same field of view (i.e., the same framing of the subject) in each format, depth of field (DoF)
130-765: A camera sensor, the Sony Alpha 99 scores 89 points, which equals the score of the Nikon D4 and the Phase One P65 Plus medium format camera, with the Nikon D800E, D800 and D600 being the only digital SLRs that get a higher score. Therefore, as of September 2013, the Sony Alpha 99 scores higher than all DSLRs from Canon and all DSLRs except those listed here from Nikon, including their professional models.

156-437: A full-frame sensor can exceed twenty times the costs for an APS-C sensor. Only 20 full-frame sensors will fit on an 8-inch (200 mm) silicon wafer, and yield is comparatively low because the sensor's large area makes it very vulnerable to contaminants—20 evenly distributed defects could theoretically ruin an entire wafer. Additionally, when full-frame sensors were first produced, they required three separate exposures during
182-994: A given lens; they had no crop factor with respect to angle of view. The first full-frame DSLR cameras were developed in Japan from around 2000 to 2002: the MZ-D by Pentax , the N Digital by Contax 's Japanese R6D team, and the EOS-1Ds by Canon . Nikon has designated its full frame cameras as FX format and its smaller sensor interchangeable-lens camera formats as DX and CX .

208-407: A number of advantages compared to their smaller-sensor counterparts. One advantage is that wide-angle lenses designed for full-frame 35 mm retain that same wide angle of view . On smaller-sensor DSLRs, wide-angle lenses have smaller angles of view equivalent to those of longer-focal-length lenses on 35 mm film cameras. For example, a 24 mm lens on a camera with a crop factor of 1.5 has
234-403: A press of the central button and then changed using the dial silently during movie or still recording. The dial's functions can also be changed on the fly by long-pressing the button and then selecting whichever function is desired. For flexibility Sony α99 allows users to use Sony's crop APS-C DT lenses and consequently automatically cropping the image to the smaller frame. An updated version,
260-524: A size equivalent to APS-C -size film), much smaller than a full 35 mm frame. Many digital cameras, both compact and SLR models, use a smaller-than-35 mm frame as it is easier and cheaper to manufacture imaging sensors at a smaller size. Historically, the earliest digital SLR models, such as the Nikon NASA F4 or Kodak DCS 100 , also used a smaller sensor. Kodak states that 35 mm film (note: in " Academy format ", 21.0 mm × 15.2 mm) has
286-610: A wide-angle lens, this requires a retrofocus design, which is generally of inferior optical quality. Because a cropped-format sensor can have a smaller mirror, less clearance is needed, and some lenses, such as the EF-S lenses for the Canon APS-C sized bodies, are designed with a shorter back-focus distance ; however, they cannot be used on bodies with larger sensors. The full-frame sensor can also be useful with wide-angle perspective control or tilt/shift lenses; in particular,

#1732797912677312-411: Is a digital single-lens reflex camera (DSLR) with a 35 mm image sensor format ( 36 mm × 24 mm ). Historically, 35 mm was one of the standard film formats, alongside larger ones, such as medium format and large format . The full-frame DSLR is in contrast to full-frame mirrorless interchangeable-lens cameras , and DSLR and mirrorless cameras with smaller sensors (for instance, those with
338-414: Is in inverse proportion to the format sizes, so for the same f -number, the full-frame format will have less DoF. Equivalently, for the same DoF, the full-frame format will require a larger f -number (that is, a smaller aperture diameter). This relationship is approximate and holds for moderate subject distances, breaking down as the distance with the smaller format approaches the hyperfocal distance, and as
364-465: Is the cross section of the cone of light transmitted by a lens or series of lenses onto the image plane . When this light strikes a perpendicular target such as photographic film or a digital camera sensor , it forms a circle of light – the image circle. Various sensor aspect ratios may be used which all fit inside the same image circle, 3:2, 4:3, 16:9, etc. A lens to be used on a camera that provides movements must have an image circle larger than
390-660: The Sony α99 II , was announced at Photokina in September 2016. Model variants of the Alpha 99 camera body: In February 2014, Hasselblad introduced a restyled Sony A99 as Hasselblad HV. According to the company's press-release, their version of A99 is "tough as nails", featuring more robust construction than the original. In the DxOMark Overall Sensor Score test, which is based on all characteristics of
416-527: The photolithography stage, tripling the number of masks and exposure processes. Modern photolithography equipment now allows single-pass exposures for full-frame sensors, but other size-related production constraints remain much the same. Some full-frame DSLRs intended mainly for professional use include more features than typical consumer-grade DSLRs, so some of their larger dimensions and increased mass result from more rugged construction and additional features as opposed to this being an inherent consequence of
442-534: The advantage of allowing more light to be captured before over saturation of the photodiode. Additionally, less noise is generated by adjacent pixels and their emf fields with larger photodiodes or greater spacing between photodiodes. For a given number of pixels, the larger sensor allows for larger pixels or photosites that provide wider dynamic range and lower noise at high ISO levels. As a consequence, full-frame DSLRs may produce better quality images in certain high contrast or low light situations. Production costs for
468-478: The center of the lenses image circle is captured. The edges are cropped off, which is equivalent to zooming in on the center section of the imaging area. The ratio of the size of the full-frame 35 mm format to the size of the smaller format is known as the " crop factor " or "focal-length multiplier", and is typically in the range 1.3–2.0 for non-full-frame digital SLRs. When used with lenses designed for full frame film or digital cameras, full-frame DSLRs offer
494-422: The equivalent of 6K horizontal resolution, according to a senior vice president of IMAX. This equates to 10K horizontal resolution in full-frame size. If the lens mounts are compatible, many lenses, including manual-focus models, designed for 35 mm cameras can be mounted on DSLR cameras. When a lens designed for a full-frame camera, whether film or digital, is mounted on a DSLR with a smaller sensor size, only
520-476: The full-frame sensor. The Nikon E2/E2s (1994), E2N/E2NS (1996) and E3/E3S (1998) digital SLRs as well as the similar Fujifilm Fujix DS-505/DS-515, DS-505A/DS-515A and DS-560/DS-565 models used a reduction optical system (ROS) to compress a full-frame 35 mm field onto a smaller 2/3-inch (11 mm diagonal) CCD imager . They were therefore not digital SLRs with full-frame sensors, however had an angle of view equivalent to full-frame digital SLRs for
546-402: The magnification with the larger format approaches the macro range. There are optical quality implications as well—not only because the image from the lens is effectively cropped—but because many lens designs are now optimized for sensors smaller than 36 mm × 24 mm . The rear element of any SLR lens must have clearance for the camera's reflex mirror to move up when the shutter is released; with

This allows use of standard ISO hotshoe accessories without the need for adapters as in previous Alpha models. The camera ships with an adapter to allow use of older Minolta-style hot-shoe accessories. Like Sony's APS-c flagship, α77 , the α99 has the ability to record Full HD 1080 video with up to 60p frame rate. In markets outside China, this camera also has built-in GPS that allows recording of position information into
598-448: The photo. The α99 also uses a three-way tiltable LCD, as used on α77, this feature allows the photographer to view the LCD from any angle. Alongside the lens mount Sony has replaced the traditional autofocus mode selection dial with a "Silent Multi-Controller" which is a customizable dial with silent detents and a central button used for confirmation. The dial's function can be brought up with
624-417: The size of the image format (Adams 1980, 54). To avoid vignetting , a photographer using a view camera must ensure that the area remains within the image circle (Adams 1980, 56–57; 151–52; 157–61); a tilt/shift lens or perspective-control lens used on a small- or medium-format camera usually has mechanical limitations that keep the frame area within the image circle. This photography-related article
650-457: The use of lower cost lenses without corresponding loss of quality. Finally, full frame sensors allow for sensor designs that result in lower noise levels at high ISO and a greater dynamic range in captured images. Pixel density is lower on full frame sensors. This means the pixels can be either spaced further apart from each other, or each photodiode can be manufactured at a slightly larger size. Larger pixel sizes can capture more light which has
676-422: The wider angle of view is often more suitable for architectural photography . While full-frame DSLRs offer advantages for wide-angle photography, smaller-sensor DSLRs offer some advantages for telephoto photography because the smaller angle of view of small-sensor DSLRs enhances the telephoto effect of the lenses. For example, a 200 mm lens on a camera with a crop factor of 1.5× has the same angle of view as
