Proving the DSLR is still a highly capable tool, the Pentax K-3 Mark III marries contemporary imaging capabilities with the trusty and familiar design of an SLR. Taking the flagship spot in Pentax's APS-C lineup, the K-3 Mark III is characterized by a new 25.7MP BSI CMOS sensor, a high-density 101-point AF system, a revised pentaprism optical viewfinder, and an advanced SR II Shake Reduction System. As a Pentax, too, the K-3 Mark III is also distinguished by its robust physical construction and extensive weather sealing for working in harsh weather conditions and climates.

The K-3 Mark III's updated sensor and processing capabilities offer a blend of high-resolution stills performance with apt speed to suit a variety of shooting scenarios. Up to 12 fps continuous shooting is possible along with UHD 4K video recording. For stills, a new SAFOX 13 AF system features 101 phase-detection points for quick and accurate focusing performance with apt subject tracking capabilities.

Complementing the imaging, this camera relies on Pentax's attention to details and how cameras are handled and used, and as such features a tough and robust physical construction with an ergonomic design and intuitive controls. The improved optical viewfinder provides realistic and detailed eye-level viewing while the rear 3.2" 1.62m-dot touchscreen LCD offers easy control over settings and image review. The K-3 Mark III is also benefitted by dual SD memory card slots, both Wi-Fi and Bluetooth wireless interfaces, and a revised button design for more direct access to exposure and AF point control.

25.7MP APS-C BSI CMOS Sensor
Featuring a revised APS-C-format 25.7MP CMOS sensor, the K-3 Mark III's sensor sports a BSI design that promotes low noise, smooth tones, and accurate color rendering throughout the sensitivity range, from ISO 100-1600000, to suit working in a variety of lighting conditions. The sensor is paired with an updated PRIME V image processor, too, which achieves quick performance and processing to benefit both stills and video recording. Full-resolution continuous shooting up to 12 fps is also possible, along with UHD 4K video recording at 30p.
SR II In-Body Shake Reduction
Distinct among DSLRs, an advanced 5-axis SR II Shake Reduction system provides 5.5 stop-effective image stabilization performance with select lenses. This in-body IS system helps to greatly reduce the appearance of camera shake when shooting handheld with slower shutter speeds, making it easier to work in more difficult lighting conditions.

Beyond controlling camera shake, the SR II mechanism also benefits stills applications by enabling a Pixel Shift Resolution feature and an AA Filter Simulator function. Pixel Shift Resolution shifts the sensor in small increments in sequential shots in order to capture full color information at each pixel site, then composites these sequential frames to produce a single image with richer detail and resolution. The AA Filter Simulator, on the other hand, utilizes microscopic vibrations during the capture process to help mitigate moiré in order to produce clean renderings of fabrics and other high-frequency materials. This system works in conjunction with the sensor that lacks an AA filter, so you have the choice between gaining the most resolution or reducing moiré under specific scenarios.
SAFOX 13 Phase-Detection AF
Updated with more points and improved coverage, the SAFOX 13 autofocus sensor is a phase-detection focusing system that uses 101 individual points, including 25 cross-type sensors in the middle of the image frame. This array benefits focusing speed and accuracy in a variety of lighting conditions, down to -4 EV. Additionally, a new 307000-pixel RGBIr sensor and new tracking algorithm also promote more accurate tracking of subjects, even when moving at varying speeds or in irregular directions.
Body Design
  • Large and bright optical pentaprism viewfinder provides an impressive 1.05x magnification and covers 100% of the image frame for clear and accurate eye-level viewing. The pentaprism's design has also been updated to use high-refraction glass, optimized coatings, and a distortion-correcting element to reduce aberrations and promote high clarity and color fidelity.
  • Rear 3.2" 1.62m-dot touchscreen LCD is a large and bright means for image review, menu navigation, and live view shooting. This screen is also benefitted by a Night Vision function that adjusts the screen's brightness depending on the shooting conditions.
  • Typical of Pentax's designs, a sturdy and weather-resistant construction is featured for use in trying weather conditions. The chassis is built from lightweight-yet-durable magnesium alloy and is fitted with a series of dust- and moisture-resistant seals to protect against various weather conditions. The camera is also freezeproof down to 14°F and the durability is carried over to the shutter unit as well, which is rated for 300,000 shutter actuations.
  • Both 3.5mm microphone and headphone ports are featured to benefit audio performance while recording video.
  • Updated control scheme includes a new AF point selector lever for intuitive point selection; a Hyper Operation system with a new Advanced mode for more intuitive exposure mode control; an Operation Control Lock function to prevent accidental settings changes; and a new Smart Function mode and dedicated button for quick selection of settings and functions.
  • Included D-LI90 rechargeable lithium-ion battery provides approximately 800 shots per charge and the camera's USB Type-C port can be used for in-body battery charging.
  • Dual SD memory card slots offer flexible storage capabilities and the first card slot is compatible with the UHS-II standard for faster transfer speeds.
  • Built-in Wi-Fi and Bluetooth connectivity can be used to wirelessly share imagery or remotely control the camera via the Image Sync mobile app.
Real-Time Scene Analysis System
Using the high-density RGBIr sensor and the PRIME V image processor, the K-3 Mark III can use the Real-time Scene Analysis System to optimize exposure and AF accuracy by detecting subjects' faces and eyes with image recognition technology. This system relies on Deep Learning, an AI-based technology, for more accurate subject detection and scene judgement.
Firmware Update 1.41: Astro Tracer Type 3
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.)

Will there be cropping with DA lenses?

Will there be cropping with DA lenses?
Asked by: chris
Pentax DA lenses have an image circle size tailored to the APS-C image sensor size, which is smaller -- about 43% of the area -- than the full-frame image sensor size. This camera has an APS-C image sensor. So no, it won't be cropped with DA lenses; it has the image size intended for DA lenses. Now if you use a full-frame lens on it, then yes, that would be cropped -- 1.5 crop factor -- as expected, just like all of Pentax's previous APS-C DSLRs. That said, you would still use the 1.5 crop factor on any lens, DA or otherwise, to know what the lens' field of view will be on this camera. For example, a 50mm lens, whether DA or full-frame, will have the field of view on this camera that a 75mm lens has on full-frame cameras.

Are my lenses from my K-5 compatible with the K-3?
Asked by: SCOTT
Yes, the K-3 iii should be compatible with every K-mount lens ever made, going all the way back to the very first K-mount lenses made in 1975. If a lens works on your K-5, it should work on the K-3 iii. As with all previous Pentax DSLRs, there is a special step to get a meter reading with old lenses that don't have an "A" setting on their aperture ring. Most of these lenses are 1970s & 80s vintage. Apparently the K-3 iii has even better compatibility with those old lenses than previous Pentax DSLRS.
