This article discusses the cameras – mainly 35 mm SLRs – manufactured by Pentax Ricoh Imaging Corp. and its predecessors, Pentax Corporation and Asahi Optical Co., Ltd.. Pentax must not be confused with Pentax 6x7 or Pentax 67 which are 120 medium format 6x7cm film cameras.
The Ricoh 500SE digital compact camera is suitable for outdoor photography and networkability. Capability includes external information such as GPS position or barcode numbers within the image headers. External vendors sell hardware and software for workflows involving GPS positioning or barcode scanning. Most NMEA compliant Bluetooth GPS receivers can be used with this camera through its built in Bluetooth communication capability. The body is resistant to dust and water, making it robust for many environments.
A mirrorless camera is a digital camera which, in contrast to DSLRs, does not use a mirror in order to ensure that the image presented to the photographer through the viewfinder is identical to that taken by the camera. They have come to replace DSLRs, which have historically dominated interchangeable lens cameras. Other terms include electronic viewfinder interchangeable lens (EVIL) cameras and compact system cameras (CSCs).
The Pentax Q series is a series of mirrorless interchangeable-lens cameras made by Pentax and introduced in 2011 with the initial model Pentax Q. As of September 2012, it was the world's smallest, lightest interchangeable lens digital camera. The first models used a 1/2.3" back-illuminated sensor CMOS image sensor. The Q7, introduced in June 2013, uses a larger 1/1.7" type sensor. The Q system is now discontinued.
Pentax K-01 is a mirrorless interchangeable-lens camera announced in February 2012. It uses the Pentax K mount.
The Pentax K-3 is a 24-megapixel Pentax high-end digital single-lens reflex camera with an APS-C sensor, announced on 7 October 2013. The Pentax K-3 is the successor to both the K-5 II and K-5 IIs models, which have a 16-megapixel sensor. The K-5 II had an optical low pass filter or anti-aliasing (AA) filter that can prevent the appearance of moire patterning on the captured image. This filter reduces the sharpness of the image, so Pentax also produced the K-5 IIs which omitted this filter. In the K-3, Pentax obviated the need for providing two separate models by including a selectable AA filter "simulator". This mechanism vibrates the sensor when switched on, slightly blurring the image in a way that replaces the function of the optical AA filter, providing the same benefit as the filter in the K-5 II and other cameras with an optical AA filter. When the AA simulator is disabled, the sensor records a sharper image, as in the K-5 IIs.
The Ricoh GR is a series of point-and-shoot, or compact, digital cameras made by Ricoh. The GR name was previously used for Ricoh's GR series of film cameras. Like the GR film cameras and Fujifilm X70, the GR digital cameras use metal bodies fitted with bright, permanently-attached prime lenses. In general, the GR digital cameras follow the precedent set by the original GR1 (1996) with lenses that provide a field of view equivalent to a 28 mm wide angle lens on a 35mm film camera.
The Pentax K-1 is the first production Pentax full-frame digital SLR camera. As the flagship model of the Pentax K-mount system, it includes several new and improved features, including a five-axis SR II in-body image stabilization system, newly designed flexible tilt articulating screen mounted on four metal struts allowing for rotation about the optical axis in addition to upward and downward tilt, and improved autofocus and metering systems.
Ricoh is a Japanese multinational imaging and electronics company.
