The PENTAX K-3 Mark III builds on the PENTAX legacy of outstanding image quality, incorporating a back-illuminated CMOS image sensor with approximately 25.73 effective megapixels. By coupling this sensor with an AA (anti-aliasing) filter- free optical design, the camera produces super-high-resolution images.
A new, super-bright optical viewfinder delivers a nearly 100% field of view and magnification of approximately 1.05 times. With a newly developed high-refraction glass prism, the viewfinder provides a wide field of view equivalent to that of a full-frame SLR, fully immersing the photographer in shooting. It features a high-performance, five-axis shake-reduction (SR) system and the innovative Pixel Shift Resolution System.
The camera's PENTAX Real-time Scene Analysis System, supported by the latest artificial intelligence technology, assists the camera in optimizing exposure settings and improving autofocusing accuracy, assuring more accurate subject detection and more reliable scene judgment.
The high-definition 3.2-inch touch-screen LCD monitor-the first touch screen in the PENTAX K series, improves efficiency and operability. Its compact, rugged dustproof and weather resistant body makes it suitable for use in the most extreme environmental conditions.
Optical Viewfinder With Nearly 100% Field Of View & Approximately 1.05 Times Magnification
The PENTAX K-3 Mark III features an optical viewfinder with a nearly 100-percent field of view and a magnification of approximately 1.05 times. A newly developed, high-refraction glass prism assures comfortable viewing with a wide field of view equivalent to that of a full-frame SLR. Also, by using a distortion-correcting optical element and optimizing the lens coatings, it delivers a clear, true-to-life viewfinder image free of distortion.
Back Illuminated CMOS Image Sensor
The PENTAX K-3 Mark III is equipped with a back-illuminated CMOS image sensor with approximately 25.73 effective megapixels. By coupling this sensor with an AA (anti-aliasing) filter-free optical design, the camera produces super high resolution images.
The newly developed, high-performance PRIME V imaging engine and new-generation accelerator unit delivers well-defined images with minimal noise, while retaining high-resolution reproduction at all sensitivities-even in the super-low or super-high range. By greatly improving the noise-reduction performance at high-sensitivity ranges, it boasts a top sensitivity of ISO 1600000 to extend the range of scenes that can be photographed.
High Speed Continuous Shooting
Thanks to a newly developed mirror-driving mechanism assuring high-speed, high-accuracy control of the mirror and shutter mechanisms, and the high-performance PRIME V imaging engine that performs high-speed data transmission, the PENTAX K-3 Mark III provides high-speed drive continuous shooting - with a maximum speed of approximately 12 images per second in the AF.S mode, or approximately 11 images per second in the AF.C mode.
User Friendly Shooting Functions
• PENTAX-exclusive Hyper Operation system, featuring a new Advanced mode for more flexible exposure control
• Operation Control Lock function, to prevent accidental operational errors of exposure-setting buttons and the four-way controller
• New-generation Smart Function with the dedicated Smart Function button, for speedy selection and setting of various functions without the need of switching on-screen menus
• Button Customization function, to assign user-selected functions to 10 different control buttons
Compact Sturdy Body With Dust & Weatherproof Construction
The PENTAX K-3 Mark III's top, bottom, front and rear panels are all made of lightweight, high-rigidity magnesium alloy. Coupled with a dustproof, weather-resistant construction with special seals applied to crucial parts of the camera body, and outstanding cold-resistant performance to ensure stable operation at -10 Degree C, the camera is designed to be extremely durable and dependable even in harsh environmental conditions. The camera also features a durable, dependable shutter unit - verified in an endurance test of 300,000 shutter-release actions -to perfect the rugged body for worry-free shooting at any location.
4K Resolution Movie Recording
The PENTAX K-3 Mark III captures 4K-resolution movie clips (3840 x 2160 pixels;30p/24p frame rate) or Full HD movie clips (1920 x 1080 pixels; 60p/30p/24p frame rate) in the H-264 recording format. Equipped with a stereo microphone input terminal and headset terminal, it also allows the user to manually set the audio recording level and monitor the sound pressure level for microphone input. Thanks to quiet touch-screen control on the LCD monitor positioned on its back panel, the desired shooting function and exposure compensation level can be set without worrying about operational noise.
Pentax K-3 Mark III Features
- DR II (Dust Removal II) mechanism, for effective removal of dust particles using ultrasonic vibrations
- Effortless recharging of the camera battery via USB Type-C terminal
- Outdoor-friendly monitor with a Night Vision LCD Display function, for speedy adjustment of the monitor's brightness level depending on the shooting location
- HDR (High Dynamic Range) function, for simplifying handheld photography and saving captured images as RAW-format files
- Dual SD-card slot (with Slot One conforming to the UHS-II standard)
- Ergonomic design of camera exterior and control parts, optimized to accommodate different hand sizes and finger lengths
- Compatibility with old lenses without electronic contacts, for shooting in the Av (Aperture-priority) mode and saving the lens focal length as Exif data
Firmware version 1.41 allows this camera to be used as an astro tracer without the optional Pentax O-GPS1 GPS Module. The camera enables astro tracing without GPS, direction, or other data, so there is no need for GPS positioning or to perform precision calibration. In addition, astro tracing can operate in areas affected by magnetic fields. Before starting, a preliminary shot is taken to track the object based on the movement of stars. (It is, however, recommended to use the O-GPS1 for star photography when shooting with a wide-angle lens.)
