Full-featured mid-level DSLR with fast advanced functionality and weather-resistant design

The K-50 offers advanced features and outstanding operability in a compact, weather-resistant, coldproof and lightweight body for worry-free outdoor photography. Featuring specifications of a top level DSLR, enjoy a 16.28 megapixel APS-C CMOS sensor, fast continuous shooting at six frames per second, ISO up to 51200, 100% field of view, innovative in-body shake reduction, an advanced auto focus module and Full HD video recording. The K-50’s available in 120 brilliant colour combinations so you can customize your K-50 to match your personal style.

Colour Choices:

High-resolution, super-high-sensitivity shooting at ISO 51200

The state-of-the-art CMOS image sensor with a large image-capturing area measuring 23.7mm by 15.7mm assures high-speed image data readout. This image sensor is coupled with PRIME M imaging engine to deliver super-high-resolution, rich-gradation digital images with approximately 16.28 effective megapixels. High sensitivity shooting up to ISO 51200 improves noise performance throughout, even in low lighting.

Fully Weather-sealed, Dustproof, Coldproof Design

With 81 weather seals throughout the entire body, the K-50 ensures worry-free use in any weather condition or outdoor setting, be it rain or sand. The K-50’s rugged, coldproof design is also perfect for use in wet, snowy winter conditions, at temperatures as low as -10°C

High-speed continuous shooting, at approximately six images per second

The K-50 allows you to record active, fast-moving subjects in a series of images, at a maximum speed of approximately six images per second (in the JPEG recording format). A maximum 1/6000 second shutter speed freezes sports and fast action without subject movement blur.

Pentaprism Viewfinder for 100% Field of View

Despite its compact size, the K-50 features a glass prism finder with nearly 100% field of view and approximately 0.92-times magnification (with a 50mm F1.4 lens at infinity) to cover the entire field of view for easy focusing and framing. It delivers a clear view of the subject even in bright sunshine and eliminates parallax and time lag in the viewfinder image.

Innovative SR mechanism

The PENTAX-developed SR (Shake Reduction) mechanism effectively compensates the adverse effect of camera shake to deliver sharp, blur-free images, even under shake-prone conditions such as when using a telephoto lens, shooting in the dark without flash illumination, or taking landscapes at twilight. This innovative mechanism works with almost all PENTAX interchangeable lenses — even those developed for film-format cameras.* The K-50 offers several useful features to assist you during shooting, including an Automatic Horizon Correction function to assure high-precision image framing and effortless adjustment of horizontal alignment; a Composition Adjustment function to allow minute adjustment of image alignment both to horizontal and vertical directions, as well as slant-wise rotation; and an ASTROTRACER mode to simplify astronomical photography in combination with the optional O-GPS1 GPS Unit.
* Lenses compatible with this mechanism: PENTAX K, KA, KAF, KAF2 and KAF3 mount lenses; screw-mount lenses (with an adapter); and 645 and 67system lenses (with an adapter). Some functions may not be available with certain lenses.

High-precision autofocus with SAFOX IXi+ AF module

The K-50’s state-of-the-art SAFOX IXi+ AF sensor module assures responsive, high-precision autofocus operation with 11 sensors (including nine cross-type sensors in the middle). It also features a spotbeam projector to assist AF operation at poorly lit locations. Its select-area expansion function keeps the sensor module tracking a moving subject, even when it moves out of a pre-assigned auto-tracking area, by assessing the distance data collected by neighboring focus sensors.

Eye-Fi Card Compatibility

With Eye-Fi wireless LAN SD memory cards, you can automatically transmit recorded images to a smartphone. New built-in menus allow you to easily enable automatic transmission of images and video to a smartphone for rapid sharing. You can even select favorite images and resize them before transmission.

High-quality movie recording

Full 1080p HD video capture at 30 frames per second (60 FPS for 720p) features efficient h.264 compression, flexible exposure control, and HDR finishing options for stunning video quality.

77-segment metering system

Highly accurate 77 segment metering system produces beautifully exposed images and video, even in complex lighting situations.

Traditional, Auto Picture and Scene modes

Traditional shooting modes feature PENTAX Sensitivity Priority (Sv) and Shutter And Aperture Priority (TAv) for outstanding flexibility, while powerful automatic modes like Auto Picture and Scene modes take the guesswork out of great photography.

Enhanced Creative Modes, multilayer filtering opportunities

Choose from 11 types of custom image modes and 19 digital filters, all with multi layering capabilities, for more creative expression than you ever dreamt of. The K-50 lets you show off your unique visions with real, high-resolution images.

Large High Resolution 3 inch LCD

Large 3 inch LCD with brightness and colour adjustments is wide angle viewable, and features 921,000 dots of resolution.

Dual-axis electronic level

For high precision horizontal and vertical alignment, use the electronic dual-axis level to make sure your shot is perfectly aligned with the horizon or framed just the way you want it. Measure both side-to-side and forward to backward tilt for the ideal shot.

In-body raw development and HDR shooting

Enjoy in-body raw development and in-camera HDR shooting mode, featuring multiple blending options to bring out the detail in wide gamut still imaging.

Programmable front & rear e-dials

Programmable front and rear e-dials enable PENTAX renowned Hyper Program and Manual modes, as well as other rapid no-look settings changes.

Standard Lithium-ion battery or optional use of AA-size batteries

Compatible with both rechargeable Li-Ion and AA batteries (via optional D-BH109 AA Battery Holder) for plentiful power at home or while travelling.
