Pentax K-1 features

1. High-resolution, fine-gradation images supported by approximately 36.4 effective megapixels
The K-1 features an AA (anti-aliasing) filterless design that prioritizes image resolution, as well as the new PRIME IV imaging engine, which is capable of 14-bit RAW-format image recording. The K-1’s unique full frame sensor and imaging engine design also allows for super-high-sensitivity shooting up to ISO 204800, producing beautiful, high-resolution images.

2. New-generation SR II five-axis system
In-body SR II mechanism assures optimal shake reduction performance
The SR II (Shake Reduction II) five-axis mechanism enables accurate control of the large full-frame image sensor with all compatible PENTAX interchangeable lenses.* In addition to camera shake caused by pitch and yaw, it effectively compensates for camera shake caused by horizontal and vertical shift, as well as camera shake caused by roll, which is difficult to deal with by lens-installed shake reduction mechanisms. Even when taking a panning shot, this system automatically detects the direction of the camera’s movement, and efficiently controls the SR II unit to always produce the best image possible.

Pixel Shift Resolution System with a new motion correction function
This system uses the latest super-resolution technology, which captures four images of the same scene by shifting the image sensor by a single pixel for each image, then synthesizes them into a single composite image. Compared to the conventional Bayer system, in which each pixel has only a single color data unit, this innovative system obtains all color data within each pixel. It incorporates a new motion correction function, which automatically detects a moving object during continuous shooting.

Innovative AA filter simulator to minimize moiré
By applying microscopic vibrations to the image sensor, the K-1’s AA (anti-aliasing) filter simulator provides the same level of moiré reduction as an optical AA filter.

Supportive shooting functions
Since the K-1’s SR II unit has a flexible design that tilts the image sensor unit in all directions, it provides a host of handy shooting functions, including auto level compensation, image-composition fine-adjustment, and AstroTracer, which simplifies advanced astronomical photography using a built-in GPS module.

3. Flexible tilt-type LCD monitor to accommodate various shooting angles
The K-1 features a newly designed, Flexible-tilt LCD monitor, which tilts horizontally, vertically or diagonally with a single action, without deviating from the lens’s optical axis. 35 degrees of horizontal and 44 degrees of vertical adjustment can be achieved; the LCD panel can even be laid flat up or down. The 3.2-inch LCD monitor features a tempered-glass front panel for added durability, a unique air-gapless construction effectively reduces reflection, and a new Outdoor View Setting mode allows the user to instantly choose the desired monitor brightness level.

4. Newly developed SAFOX 12 with 33 sensor points and full-frame-proportioned AF frame
The SAFOX 12 AF sensor module features 33 AF sensors (25 cross-type sensors positioned in the middle). The center sensor and the two sensors located just above and below it are designed to detect the light flux of an F2.8 lens, making it easy to obtain pinpoint focus on a subject when using a large-aperture lens.

5. Upgraded PENTAX Real-Time Scene Analysis System, with application of artificial intelligence technology
The K-1’s advanced PENTAX Real-Time Scene Analysis System performs near-instant analysis of exposure, color, movement and other factors. Combined with a breakthrough artificial intelligence technology called deep learning, the K-1 instantly optimizes settings for even the most difficult shooting situations.

6. Easy-to-focus optical viewfinder with nearly 100-percent field of view
Newly developed for its 35mm full-frame design, the K-1’s optical viewfinder provides a nearly 100-percent field of view and an approximately 0.7-times magnification. A Natural Bright Matt III focusing screen allows ease of focusing and a true-to-life rendition of defocused areas in the viewfinder image.

7. High-speed continuous shooting with a top speed of approximately 4.4 images per second
The K-1 has a larger shutter unit that easily accommodates the camera’s full-frame image sensor and provides high-speed, high-accuracy control of the mirror unit. A high-speed data transmission system incorporated in the PRIME IV imaging engine allows the user to continuously record as many as 17 images in the RAW format (or a maximum of 70 images in the JPEG Best format) in a single sequence, at a top speed of approximately 4.4 images per second.

8. Supportive shooting functions to improve picture-taking efficiency and operational comfort
• Operation assist light function, which provides LED lights above the lens mount, behind the LCD monitor, at the memory car slot, and at the cable switch terminal to facilitate fast and easy operation in poorly lit settings.
• Key lock function, which prevents erroneous operation of the four-way controller and other exposure-related control buttons.
• Smart function, which allows the user to swiftly choose and set desired functions using just the function dial and the set dial on the camera’s upper panel, without referring to the menu screen on the LCD monitor.
• Control panel customize function allows the user to change aspects of the on-screen menu.

9. Compact, solid body with dustproof, weather-resistant construction
Constructed of sturdy yet lightweight magnesium alloy with the inclusion of 87 sealing parts in the body, the K-1 also boasts a dustproof, weather-resistant and cold-resistant construction.
Other Features

• Wi-Fi operation allowing camera control and image transfer to tablet or smartphone via the free ImageSync app
• Full HD movie recording at 1920 x 1080 pixels in the H.264 recording format
• Built-in GPS module and electronic compass

• Crop mode with a choice of image area from AUTO, FF (Full Frame) and APS-C, to accommodate different types of lenses
• Clarity control and Skin Tone correction functions, a pair of the latest image processing technologies developed by RICOH Central Laboratory
• HDR (High Dynamic Range) shooting mode with RAW-format data filing, usable in handheld shooting
• The PENTAX-invented hyper operating system for quick, accurate response to the photographer’s creative intentions
• Dual SD card slots for memory card flexibility (compatible with SDXC UHS-1 speed class in SDR104 buss speed mode)
• Compensation of various parameters: lens distortion, lateral chromatic aberration, diffraction, and brightness level at image-field edges. Fringe effect compensation is also available in RAW-format processing.
• Compatibility with PENTAX Image Transmitter 2 tethering software (Software update required from RICOH IMAGING official website)
• Digital Camera Utility 5 software (latest version) included

Optional accessory:

• D-BG6 Battery Grip
This battery grip is designed to facilitate vertical-position shooting with the PENTAX K-1 camera body. It provides a shutter release button, a set of control buttons (AE lock, AF, ISO, exposure compensation, green), a preview lever, and dual electronic dials — just like those provided on the camera body. It also features the dustproof, weather-resistant construction identical to the PENTAX K-1 camera body. In addition to the dedicated lithium-ion rechargeable batteries, it also accepts six AA-size batteries.

Press release

Ricoh defines full-frame benchmark with new PENTAX full-frame DSLR offering

DENVER, Feb. 17, 2016 – Ricoh Imaging Americas Corporation today announced the PENTAX K-1 full-frame digital single-lens reflex (DSLR) camera. The K-1 combines the performance of a full-frame sensor with unique, user-friendly PENTAX technology and convenience features loved by professional and serious amateur photographers the world over.

The foundation of the PENTAX K-1 is its large, full-frame image sensor. This AA-filterless CMOS sensor with 36.4 effective megapixels sets the stage for ultimate creativity, facilitating super-high-resolution images rich in gradation and superb in high-sensitivity rendition.

Built around the full-frame sensor is a compact, high-performance weather-sealed and dustproof body with features only found in PENTAX cameras. “The K-1 is a blend of advanced, full-frame performance with the kind of features and advancements that PENTAX users have come to know and love,” said Jim Malcolm, president, Ricoh Imaging Americas Corporation. “As a result, the K-1 creates a solution for full-frame shooters that is unique in the industry.”

Within its compact body, the PENTAX K-1 features several advanced technologies that help the photographer to produce top results in a wide variety of challenging conditions. SR II Shake Reduction is a newly refined and highly sensitive five-axis shake-reduction system that is capable of reducing camera shake with a compensation range of up to five exposure steps, allowing photographers to freely move and compose – and to focus on their subjects, not the gear. SR II also facilitates other advanced PENTAX-unique features such as AA Filter Simulator, which effectively eliminates moiré effect without the need for an anti-aliasing filter, while increasing sharpness and overall image quality. Key to great autofocus performance on the K-1 is the new SAFOX 12 autofocus mechanism with 33 autofocus points, assuring fast and accurate autofocusing, even in the most demanding shooting situations.  A newly-designed optical viewfinder equipped with the famous PENTAX Pentaprism boasts a bright, nearly 100-percent field of view.

In addition to a long list of technological advancements, the PENTAX K-1 also features a number of convenience features, making camera operation fast and easy. Designed to move in ways never before imagined is the new Flexible-tilt LCD monitor—a first for any DSLR camera. This rugged yet highly adjustable display can be positioned to the desired angle horizontally and vertically, making it easy to shoot at challenging angles. Other significant firsts include the K-1’s Operation Assist Lights – small, white LEDs that facilitate camera operation in low-light environments, making it easy to change lenses, swap memory cards and adjust back-of-camera controls, and a Smart Function dial that allows photographers to easy select frequently-used functions without going into the LCD menu.

Current PENTAX lens owners will appreciate that they can incorporate their APS-C lens collection into their new PENTAX K-1 full-frame camera kit by utilizing the K-1’s Crop Mode, which offers settings in-camera for either APS-C or Full-Frame sized shooting, regardless of the attached lens. There is also an “auto” mode that detects the lens type and sets the camera accordingly.

Upon launch, PENTAX is offering 12 full-frame compatible lenses, including two new models being announced concurrent with the K-1 camera: the HD PENTAX-D FA 15-30mm f.2.8 ultra-wide angle zoom lens and the HD PENTAX-D FA 28-105mm f/3.5-5.6 compact, lightweight zoom lens. (Note: separate news releases have been issued today to provide details on each lens).

Pricing and Availability

The PENTAX K-1 camera will be available April 2016 at and retail outlets nationwide for a manufacturer’s suggested retail price of $1,799.95.

    That’s a very VERY agressive price !
    Good job Pentax !
    and it’s the first DSLR with inbody stabilisation !! awesome !

    • razec

      Not sure what you meant on the third line

      If you’re talking about full frame IBIS, Sony A900/A850 had that feature for almost a decade now,

      but if you’re talking about 5-axis IBIS on a DSLR then I agree

      • Spy Black

        I think it’s the first in a full frame DSLR, not counting mirrorless or crop frame.

        • Joseph Radhik

          The A900/A850 were very much full frame. This was 2008!

          • Spy Black

            Ah, well alright.

          • Justtakethepicture

            Love the begrudging well alright lol

          • Spy Black

            Actually it was more of an “ah well, alright, I stand corrected”, but I can see how it could be viewed as you did.

      • Aiki76

        Pentax introduced in-body stabilisation in 2006, and it is present in all their DSLR since that moment. The K1’s shake reduction is a 5 axes stabilisation, so is a great improvement of the previous technology.

  • I think I might just get one.

    • Looks like the only thing they got wrong was the funky tilting screen. Should have just been side hinged. It doesn’t look user friendly and with a design like that long term reliability is questionable IMO.

      • Cynog

        I’m not sure I would worry about that. It looks a deal more robust than the flip-out screens on some cameras like the D5500, etc, and I’m not aware of any problems with those. And hey, it has LEDs on the back!

  • Spy Black

    Now they just need to get some modern primes available for this, and/or get the third-party manufacturers to add the K-mount to their full frame offerings.

    • I could definitely go for some WR Limited primes with the modern AF motor in them. The 31 1.8 and 77 1.8 are killer options, though, since they use the in-body AF motor to be extremely compact and all-metal.

  • malchick743
  • gamer

    The problem with Pentax is the lack of modern full-frame lenses. In Nikon and Canon world you can buy some relatively cheap and quite good lenses like 35, 50 and 85mm at 1.8.
    So if Pentax introduce some new modern full-frame prime lenses at the price range $200-$400 they can compete successfully with its bigger rivals. Otherwise Pentax are doomed.

    • Thylmuc

      So, the ten full frame lenses they currently offer are not satisfactory? Are these not telecentric enough?!

      • gamer

        1. All Pentax full-frame prime lenses are produced 15-20 years ago and designed for film cameras. Their resolution does not match the new high demanding 36MP sensor.

        2. All of these lenses are extremely expensive.
        On Nikon system you can have all three lenses 35, 50 and 85mm for the total price of $1000 (modern up-to-date lenses with built-in motor, design especially for their FX bodies).
        In the Pentax world each of FA 31mm F1.8 and FA 77mm f1.8 cost $800 each, FA 50mm f1.4 for $300 – total price $1900. All these lenses are 20+ years old.

        • jar_jar_

          We haven’t seen how Pentax’s current DA 35 2.4 and 50 1.8 (and 40 2.8, 55 1.4, 70 2.4, etc.) will look on this sensor. On 35mm film, these prime lenses look great. There is a chance that they won’t look as good on FF digital, but we won’t know that until we see it. If they do look good, then they’re a very inexpensive option (that a lot of people also already have). As to how some of the other FA lenses will look on a FF digital sensors (including 36mp), there is ample evidence on Flickr from people using Pentax lenses on Sony A7’s and A7r’s. They generally look great, which is why quite a few Pentaxians made the switch while waiting for this camera.

          • 24×36

            No, actually there is NO chance they won’t look as good on FF digital as they did on 35mm film. Is there a chance people will be able to see more flaws when pixel peeping, which is the equivalent of putting your 35mm film under a micorscope? Maybe, but that is irrelevant – in particular since nobody examined their film so critically. Make same size prints from 35mm film and the K-1, and I can pretty well guarantee that lens will look better on digital than it ever did on film. (And by “film” I mean mainstream films with high enough ISO speed to be relevant for all-around photography, not some specialty film that is so slow as to be useless to photograph anything that moves.)

        • Justtakethepicture

          While you’re right about Canon and Nikon having some well priced f/1.8 lenses, you have no idea how well Pentax’s lenses will perform on this camera. Pure speculation based on minimal information.

          • BP2012

            That’s not a pure speculation, that’s a Canikon fanboys favourite lie. Nikon fanboys had that problem when they tried old Nikkor lenses on D800/810 and now they project their frustration to cameras from different brands. A lot of old Pentax lenses works very well on Sony A7R with 36MP. Even some almost 50 years old radioactive Takumars (55,85). There are also very cheap kit lenses like M 50mm f/1.7 which works greats in combination 36MP sensors. I’m 100% sure that it is possible to get better image resolution on K-1 with M 50mm f/1.7 that on D810 with any modern 50mm Nikkor lens. Even some old Pentax zooms work great on 36MP.

        • 24×36

          Horse manure. If you have quality K mount lenses, they will perform better with a 36MP digital sensor than they ever did with film or any APS-C DSLR. Good lenses didn’t “expire” when digital imaging came along. And resolution works both ways – you may not get the most from your sensor without the highest resolution lens, but you ALSO don’t get the most from your lenses without the highest resolution sensor behind them.

  • dat price doe…

  • Skinny Pete

    Very interesting specs and price point. The one thing that caught my attention was the 4.4 burst rate in full-frame mode. I’m sure there are some physical/mechanical reasons behind a “slower” frame rate. I expected 6 frames per second but I suppose I’m splitting hairs here.

    Still, a long awaited addition to the full-frame world. Well done Pentax/Ricoh!

  • NightPhotographer

    Can EFCS be activated for live view stills?

    • Kunzite

      Electronic shutter can be used for live view stills.

      • NightPhotographer

        Has it been announced or it is your speculation?

        • Kunzite

          Found it on Ricoh Imaging’s product page somewhere.

  • Larry Zapata

    Anyone wanna a nice laugh! Go read what that idiot Ken Rockwell has to say about the K-1! But the moron in a VERY OFFENSIVE way does bring up an important point about lens options on the K-1… I sure hope this partnership Ricoh has with Tamron also scores us the nice 35, 45, 85 1.8 primes soon!!!
