The Pentax K-50 is a 16.3-megapixel mid-level Pentax digital single-lens reflex camera , announced on 12 June 2013. It is the direct successor to the Pentax K-30 model, both of which are weather-sealed.
41-565: The main differences over the Pentax K-30 include a more traditional body design, 120 available body color combinations, higher max ISO range (up to 51 200), compatibility with Eye-Fi cards and an improved kit lens (Pentax K-30 included the DA L 18-55mm lens , while Pentax K-50 bundles a water-resistant version, the DA L 18-55mm WR, both with plastic mounts). Among competing APS-C mid-range DSLRs,
82-507: A Wi-Fi positioning system . Eye-Fi continually released upgraded versions of its hardware products, most recently the Eyefi MobiPro WiFi SD cards available in 16 GB and 32 GB capacities. Eye-Fi Cards are compatible with virtually all digital cameras manufactured since 2010. Approximately 400 models from Canon , Nikon , Sony , Olympus , Casio and others also include Eyefi firmware built into their cameras under
123-477: A service set identifier ( SSID )—typically the natural language label that users see as a network name. (For example, all of the devices that together form and use a Wi‑Fi network called "Foo" are a service set.) A service set forms a logical network of nodes operating with shared link-layer networking parameters; they form one logical network segment. A service set is either a basic service set ( BSS ) or an extended service set ( ESS ). A basic service set
164-526: A streaming media format. Once transcoded, videos can be played back on inside Eye-Fi Mobi apps and within a browser via in-app streaming at 480p resolution. Beyond storage, Eye-Fi Cloud also provides a range of features designed to simplify organization, access and sharing of private image collections. The enhanced features include machine learning -based analytics of a photo collection, branded as Smart Tags, search based organization "Smart Views" as well as more traditional tagging and album creation. Sharing
205-530: A 30-day or 1-year subscription. As of October 2015, the monthly subscription for Eye-Fi Cloud was US$ 4.99 and the annual subscription was $ 49.99. Active Eye-Fi Cloud subscriptions support unlimited storage for photos and up to 300 videos of up to 15-minutes per month. In 2016, Eye-Fi Cloud was purchased by a subsidiary of the Japanese company Ricoh , and rebranded as Keenai. The service is defunct as of December 1, 2018. Some portable document scanners such as
246-412: A dependence on a distribution point to relay traffic between them. In this form of peer-to-peer wireless networking, the peers form an independent basic service set ( IBSS ). Some of the responsibilities of a distribution point—such as defining network parameters and other "beaconing" functions—are established by the first station in an ad-hoc network. However, that station does not relay traffic between
287-484: A flag to express that the SSID is UTF-8 -encoded and could contain any Unicode text. Wireless network stacks must still be prepared to handle all possible values in the SSID field. Since the contents of an SSID field are arbitrary, the 802.11 standard permits devices to advertise the presence of a wireless network with beacon packets in which the SSID field is set to null. A null SSID (the SSID element's length field
328-479: A hub for all user devices to sync their private photo collection. Original image files are retained in Eye-Fi Cloud and photo are then saved in a compressed JPEG file format to save space on synchronized devices. The original files are always available via browser access to Eye-Fi Cloud (app.eyefi.com). Video files transferred to Eye-Fi Cloud are also saved in their original format but are also transcoded into
369-467: A local computer or a mobile device such as a smartphone or tablet computer . The company ceased business in 2016. Eye-Fi offered multiple models that varied in data transfer speed, storage capacity, and the provided software and other services. Eye-Fi was originally known for its Wi-Fi enabled SD card ("Cards") product line which began commercial shipments in 2007. Starting in 2009, Eye-Fi Geo and subsequent products offered geotagging of photos using
410-466: A serial number or a MAC address of another network interface. As with the MAC addresses used for Ethernet devices, an infrastructure BSSID is a combination of a 24-bit organizationally unique identifier (OUI, the manufacturer's identity) and a 24-bit serial number. A BSSID with a value of all 1s is used to indicate the wildcard BSSID, usable only during probe requests or for communications that take place outside
451-641: A service set. Normally it is broadcast in the clear by stations in beacon packets to announce the presence of a network and seen by users as a wireless network name. Unlike basic service set identifiers, SSIDs are usually customizable. These SSIDs can be zero to 32 octets long, and are, for convenience, usually in a natural language , such as English. The 802.11 standards prior to the 2012 edition did not define any particular encoding or representation for SSIDs, which were expected to be treated and handled as an arbitrary sequence of 0–32 octets that are not limited to printable characters . IEEE Std 802.11-2012 defines

#1732782777418492-415: A single network to the logical link control layer by using the same SSID. Thus, from the perspective of the logical link control layer, stations within an ESS may communicate with one another, and mobile stations may move transparently from one participating basic service set to another (within the same ESS). Extended service sets make possible distribution services such as centralized authentication. From
533-819: Is a peer-to-peer transfer between the Card and the device running the Eyefi app. Infrastructure transfer is accomplished when both the Card and the device running the Eyefi Mobi app are within range of the same router based network. In the latter case, the Eyefi Mobi Pro card must be set-up to recognize the SSID and password of the router-based network. Configuration of the Eyefi Mobi Pro Card to enable selective transfer as well as set-up for router based transfer
574-442: Is a subgroup, within a service set, of devices that share physical-layer medium access characteristics (e.g. radio frequency, modulation scheme, security settings) such that they are wirelessly networked. The basic service set is defined by a basic service set identifier ( BSSID ) shared by all devices within it. The BSSID is a 48-bit label that conforms to MAC-48 conventions. While a device may have multiple BSSIDs, usually each BSSID
615-427: Is a wireless network, created by multiple access points, which appears to users as a single, seamless network, such as a network covering a home or office that is too large for reliable coverage by a single access point. It is a set of one or more infrastructure basic service sets on a common logical network segment (i.e. same IP subnet and VLAN). Key to the concept is that the participating basic service sets appear as
656-464: Is accomplished by installing the Eyefi Mobi app on the user's device. Once installed, the user is directed to insert the Eyefi Card into their camera and to capture a photo or video. When users start the Eyefi Mobi app on their device the first time, they are prompted to enter the "activation code" for their Eyefi Card. The activation code is provided on a card inside the Eyefi product packaging. Once
697-526: Is accomplished using the Eyefi Mobi Desktop apps on Mac and Windows PC platforms. Eyefi Mobi Cards only support direct mode, automatic file transfer, so no desktop set-up is required. The card was designed by Eye-Fi and is manufactured in Thailand with proprietary and off-the-shelf components. The company abruptly announced on June 30, 2016, that, due to security vulnerabilities present in
738-475: Is accomplished via a variety of methods and generally intended for limited private sharing to individuals and small groups. Eye-Fi Cloud is free for one year following activation for users who purchase an Eye-Fi Mobi Pro version of the products. Eye-Fi Mobi apps are free for perpetual use with any Eye-Fi Mobi branded product. Eye-Fi Cloud for smartphones and cameras with built-in Wi-Fi is available only to users with
779-461: Is associated with at most one basic service set at a time. A basic service set should not be confused with the coverage area of an access point, known as the basic service area ( BSA ). An infrastructure BSS is created by an infrastructure device called an access point ( AP ) for other devices to join. (Note that the term IBSS is not used for this type of BSS but refers to the independent type discussed below.) The operating parameters of
820-485: Is set to zero ) is called a wildcard SSID in IEEE 802.11 standards documents, and as a no broadcast SSID or hidden SSID in the context of beacon announcements, and can be used, for example, in enterprise and mesh networks to steer a client to a particular (e.g. less utilized) access point. A station may also likewise transmit packets in which the SSID field is set to null; this prompts an associated access point to send
861-705: The Doxie Go + Wi-Fi and the Xerox Mobile Scanner make use of an Eye-Fi card to provide Wi-Fi capability for document upload. Eye-Fi support for the Xerox scanner was discontinued with the end of support for older generation cards; the scanner continued to be sold as the Xerox Mobile Scanner SD, without Eye-Fi support. Eye-Fi has won the following recognition: In November 2007, The Wall Street Journal writer Katherine Boehret called

#1732782777418902-490: The "one-time release" of a new, Mac-only software utility "to allow more time for customers seeking an alternative WiFi SD card solution." No updates or support were offered. The third-party command line utility eyefi-config can be used to retrieve a compatible card's authentication data, which can then be used to manually configure appropriate client software. Eye-Fi released all new software starting in June 2014 based on

Discontinued models include "Explore X2", "Geo X2", "Pro", "Geo", "Home/Video", "Share/Video", "Explore Video" and an "Anniversary Edition". SSID In IEEE 802.11 wireless local area networking standards (including Wi‑Fi ), a service set is a group of wireless network devices which share
984-555: The Card are automatically sent to the device running the Eyefi Mobi app. This mode is referred to as "automatic transfer". In addition, the Mobi Pro product line provides for a "selective transfer" mode in which only photos designated by the user are transferred to the Eyefi Mobi app. Identification of which files to transfer is accomplished using an in-camera operation, usually consistent with files designated as "protected" or "locked". Initial set-up of Eyefi Mobi and Eyefi Mobi Pro Cards
1025-555: The Eye-Fi Connected branding. Eyefi Connected cameras are able to control various functions of the Eye-Fi Cards, including the ability to manually turn the Wi-Fi feature on/off. The core feature of all Eyefi Cards is the ability to automatically detect when a new image file has been captured on a camera. Once a device running the Eyefi Mobi software detects the presence of an Eyefi Mobi Card, any new images captured on
1066-549: The Eye-Fi Mobi WiFi SD memory card. The company announced in October 2015 that the apps will also directly connect to cameras with built-in Wi-Fi radio modules such as GoPro, and selected models from Canon, Casio, Nikon and Olympus. New photos and videos received into Eye-Fi Mobi apps are saved locally to the native device and optionally can be synchronized to the Eye-Fi Cloud "storage" service. Eye-Fi Cloud provides
1107-506: The Eye-Fi Mobi product line. The Eye-Fi Mobi apps and desktop software are proprietary software products available for Apple and Microsoft 's desktop and mobile operating systems, and Google 's mobile operating system . Third-party free software exists to enable Eye-Fi cards to be accessed from Linux but the platform is not officially supported. Eye-Fi Mobi apps are able to receive photos and videos from cameras equipped with
1148-573: The Eye-Fi card "a terrific little tool". The magazine Wired placed the Eye-Fi Pro on their "2009 Wish List", calling it " Arbus meets Airbus ". In October 2010, Time magazine technology editor Peter Ha placed the original 2 GB Eye-Fi card on his list of "the 100 greatest and most influential gadgets from 1923 to the present". Eye-Fi was founded in 2005 by Yuval Koren, Ziv Gillat, Eugene Feinberg and Berend Ozceri. Jef Holove became

1230-635: The Pentax K-50 has the smallest body, although it is 4 mm wider than its nearest rival, the Nikon D5300 . The body is made from stainless steel and polycarbonate resin, as is the Canon EOS 700D . The Pentax K-50 has an onboard microphone but lacks the audio-in port of most comparable cameras, limiting its usefulness to videographers. Pentax is the only company to include a weather-resistant kit lens, Pentax K-50 with DA L 18-55mm f3.5-5.6 WR, while
1271-517: The cards, all previous generation cards (X2 and before) would cease to be supported by the company's proprietary software after September 16, 2016. Eye-Fi said that some functions not requiring contact with its servers, such as transfer directly to a computer or mobile device and Selective Transfer, might continue to work, although this was not guaranteed. However, to continue using these modes, they had to be configured before September 16, 2016. In August 2016, in response to complaints, Eye-Fi announced

1312-433: The context of a BSS. An independent BSS ( IBSS ), or ad hoc network , is created by peer devices among themselves without network infrastructure. A temporary network created by a cellular telephone to share its Internet access with other devices is a common example. In contrast to the stations in an infrastructure-mode network, the stations in a wireless ad hoc network communicate directly with one another, i.e. without
1353-480: The higher-model Pentax K-3 offers the 18-135mm F3.5-5.6 WR in one of its kits. The Pentax K-50 is available for around $ 300 (body only) and less than $ 400 with kit lens, as of the end of July 2015, which puts it at a very low price point compared to its competition ( Canon EOS 70D , Canon EOS 700D , Nikon D5300 , Nikon D7100 and Pentax K-3 ). The Pentax K-500 is an entry-level sibling of the Pentax K-50, sharing almost all of its features. The main differences between
1394-462: The infrastructure BSS are defined by the AP. The Wi‑Fi segments of common home and business networks are examples of this type. Each basic service set has a unique identifier, a BSSID, which is a 48-bit number that follows MAC address conventions. An infrastructure BSSID is usually non-configurable, in which case it is either preset during manufacture or mathematically derived from a preset value such as
1435-504: The mesh network, and a wireless client of that BSS is not part of the MBSS. The formation of the mesh BSS, as well as wireless traffic management (including path selection and forwarding) is negotiated between the nodes of the mesh infrastructure. The mesh BSS is distinct from the networks (which may also be wireless) used by a mesh's redistribution points to communicate with one another. The service set identifier ( SSID ) defines or extends
1476-418: The other stations; instead, the peers communicate directly with one another. Like an infrastructure BSS, an independent BSS also has a 48-bit MAC-address-like identifier. But unlike infrastructure BSS identifiers, independent BSS identifiers are not necessarily unique: the individual/group bit of the address is always set to 0 (individual), the universal/local bit of the address is always set to 1 (local), and
1517-434: The perspective of the link layer, all stations within an ESS are all on the same link, and transfer from one BSS to another is transparent to logical link control. The basic service sets formed in wireless ad hoc networks are, by definition, independent from other BSSs, and an independent BSS cannot therefore be part of an extended infrastructure. In that formal sense an independent BSS has no extended service set. However,
1558-451: The remaining 46 bits are randomly generated. A mesh basic service set ( MBSS ) is a self-contained network of mesh stations that share a mesh profile , defined in 802.11s . Each node may also be an access point hosting its own basic service set, for example using the mesh BSS to provide Internet access for local users. In such a system, the BSS created by the access point is distinct from
1599-458: The station a list of supported SSIDs. Once a device has associated with a basic service set, for efficiency, the SSID is not sent within packet headers; only BSSIDs are used for addressing. Apple 's location services interpret the SSID of a Wi‑Fi access point ending in _nomap as an opt-out from being included in Apple's crowdsourced location databases. An extended service set ( ESS )
1640-541: The two cameras are the K-500's lack of colored body options (only black), electronic level, weather sealing, and focus point visualisation through the optical viewfinder. As a consequence of the lack of weather sealing, this camera is bundled with the non-weather-sealed DA L 18-55mm kit lens, and most variants of the camera come with an AA battery holder included as opposed to the D-Li109 rechargeable Li-ion battery included with
1681-428: The user enters the code into the app, the Eyefi Card will begin transferring new files to that device. The set-up operation must be completed for any device to which the user wishes to transfer images from their camera. Once completed, there is no need to repeat the set-up. Eyefi Mobi Pro products support two major Wi-Fi network types - so called "direct" and "infrastructure" wireless networks. A direct network connection
