Introduction

The Pentax K-1 Mark II is a new professional full-frame DSLR camera that replaces the original K-1 model that was released in 2016. The Mark II is virtually identical to its predecessor in both form and function, incorporating a new accelerator unit to improve noise reduction and auto-focusing speed and adding an upgraded Pixel Shift Resolution System II with a newly developed Dynamic Pixel Shift Resolution mode for handheld shooting. In all other regards the two cameras are the same.

The Pentax K-1 Mark II is available in black for £1799 / $1999 body-only. In the US it will also be available with the FA 28-105mm F3.5-5.6 ED DC WR zoom lens for $2399.

Ease of Use

The Pentax K-1 Mark II is virtually identical to the original K-1 model, so if you don’t know anything about that camera, we strongly suggest that you head over and read our in-depth Pentax K-1 review first. In this rather brief review, we’re going to focus on the new features that the Mark II offers over and above the original version.

The new Mark II version differs in three main ways – it offers improved high sensitivity performance, high-speed Auto Focus, and image resolution through the new handheld Pixel Shift Resolution mode.

The ISO range of the K-1 II now runs from ISO 100 up to a whopping ISO 819200. As you’d maybe expect, the resulting images at such a high ISO speed are bordering on unusable (see our Image Quality page for 100% crops of each ISO speed), but more usefully ISO performance is about a stop better than on the original K-1, not really becoming visible until ISO 3200. So if you ever felt limited by the ISO range on the K-1, the new Mark II version slightly improves things.

The K-1 II’s AF Tracking algorithm has been revised to improve tracking accuracy of fast-moving subjects in the AF Continuous mode. The original K-1 was pretty sluggish in this regard, and although the new Mark II is quicker at identifying the main subject and more reliable at tracking, we still wouldn’t describe it as a great camera for sports photography.

The new handheld Dynamic Pixel Shift Resolution mode is more successful, building on the original Pixel Shift Resolution offered by the K-1. The latter is still present, requiring the camera to be mounted on a tripod. The in-body SR (shake reduction) mechanism is used to move the image sensor unit by a single pixel pitch at a time to capture four shots, which are then merged into a single image to generate an ultra high-definition image.

The new handheld Dynamic Pixel Shift Resolution mode differs by switching on the image stabilisation system, taking four similar shots, then combining them into one aligned ultra high-definition image, all whilst hand-holding the camera. It’s much like the method employed by recent smartphones like the Huawei P20 Pro, and it similarly works well with both still and moving subjects.

There are a couple of notable drawbacks, though. Firstly, you really need to use a shutter speed that’s fast enough to avoid camera shake, and secondly, unlike the normal Pixel Shift Resolution mode, it doesn’t cancel out the Bayer color array, which can lead to unwanted artifacts, moire and less detail in the resulting image. Finally, it also takes much longer for the camera to process the final image, about 20 seconds in total, so you’ll only want to use it for that “special” shot, as it completely locks the camera up.

And that’s it for the improvements offered by the Pentax K-I Mark II, other than a change to the name badge on the front and the base of the camera.

Unfortunately, though, there is one area where the Mark II takes a backwards step, namely battery life. Whereas the original K-1 offered 760-shot battery life, the new K-1 II has 670-shot life according to CIPA standards, presumably because of the new accelerator unit.

Current Pentax K-1 owners can actually get their cameras upgraded to the new functions offered by the Mark II – simply send your camera back to Pentax between May 21st and 30th September, pay the $550 / £450 service charge, and voila, your camera’s main circuit board will be replaced to add the new functions featured in the new Pentax K-1 MK II and  the current SR logo, positioned in the lower left corner of the camera’s front panel, will be replaced with the SR II logo. This is almost certainly a cheaper way of upgrading to the Mark II than selling your original camera and buying the newer model.

Image Quality

All of the sample images in this review were taken using the 36 megapixel Best JPEG setting, which gives an average image size of around 12Mb.

The Pentax K-1 Mark II produced photos of excellent quality. Noise is well controlled by the Pentax K-1 Mark II throughout the expanded range of 100-819200, first starting to appear at ISO 3200 and becoming more easily detectable at the faster settings of ISO 6400-25600 when viewing images at 100% magnification on screen (particularly in the RAW files). The fastest settings of 51200-819200 look much better on paper than in reality. Colour saturation is commendably maintained throughout the ISO range.

Pixel Shift Resolution is an effective technology that creates bigger files, finer detail and generates more accurate colours, even if the subject moves or the camera shakes slightly. The new Handheld mode does what its name suggests and allows you to create high-resolution images without having to use a tripod, although at the expense of less detail and more colour artifacts than using the tripod modes.

Image stabilisation via the camera body is a great feature that works very well when hand-holding the camera in low-light conditions or when using the telephoto end of the zoom range. An added bonus is that it works with any lens that you attach to the K-1 Mark II. The night photograph was excellent, with the maximum shutter speed of 30 seconds and Bulb mode allowing you to capture enough light in all situations.

The Digital Filters quickly produce special effects that would otherwise require you to spend a lot of time in the digital darkroom, while the Custom Images can usefully be tweaked to suit. The D-Range options help make the most out of both the shadows and highlights in a high-contrast scene (and it works for both JPEG and RAW files), while the HDR mode greatly expands the dynamic range of a JPEG by combining three differently exposed images in-camera.

The multi exposure mode combines between two and 2,000 different JPEG or RAW images into a single photo, while the anti-aliasing simulator helps to reduce moire without the need for an actual optical filter.

Pixel Shift Resolution

The in-body SR (shake reduction) mechanism is used to move the image sensor unit by a single pixel pitch at a time to capture four shots (the use of a tripod is strongly recommended). Pixel Shift Resolution merges those shots into a single image to generate an ultra high-definition image. This method differs from the traditional Bayer method, which acquires only a single element of color information for single pixel, by acquiring all RGB color information for individual pixel. This difference makes it excellent for detail and color reproduction, creating super high-definition images. This also prevents false colors from occurring theoretically, and also has a high-sensitivity noise reduction effect when compared to normal shooting.

The new handheld Dynamic Pixel Shift Resolution mode differs, though, by switching on image stabilisation, taking four similar shots, then combining them into one aligned ultra high-definition image. Unlike the normal Pixel Shift Resolution mode, it doesn’t cancel out the Bayer color array, which can lead to unwanted artifacts, moire and less detail in the resulting image. It does have an advantage under indoor lights, however, as it uses the mechanical shutter rather than the electronic one, as used by the normal Pixel Shift Resolution mode, which can result in unwanted banding.

Night

The Pentax K-1 Mark II lets you dial in shutter speeds of up to 30 seconds and has a Bulb mode as well, which is very good news if you are seriously interested in night photography. The shot below was taken using a shutter speed of 30 seconds at ISO 100.

Shake Reduction

The Pentax K-1 Mark II has a Shake Reduction mechanism built into the camera body, which allows you to take sharp photos at slower shutter speeds than other digital cameras. To test this, we took 2 handheld shots of the same subject with the same settings. The first shot was taken with Shake Reduction turned off, the second with it turned on. Here is a 100% crop of the image to show the results. As you can see, with Shake Reduction turned on, the images are sharper than when it’s turned off.

Rather than an optical anti-aliasing filter in the camera, the K-1 has an anti-aliasing simulator instead, which can be turned off (default setting) or on to either the Type1 or Type2 setting.

D-Range

Similar to Nikon’s D-lighting, Sony’s DRO, and Olympus’ Shadow Adjustment Technology, Pentax’s D-Range allows you to correct the highlights (On or Off) and/or the shadows (3 different levels) before taking a JPEG or RAW image. Although this option is always at your disposal, remember that it is meant to be used in strong, contrasty lighting at base ISO. Below you can see a comparison between Off and both highlight and shadow correction set to on/full strength; the difference is mainly noticeable in the shadowed areas on the left and right sides of the photo.

HDR Capture

The Pentax K-1 Mark II’s HDR Capture option takes three images with different exposures, and then records a single image that combines the properly exposed parts of each one, expanding its dynamic range. Here is an example which was shot with the five different modes (Off, 1, 2, 3 and Advanced). Although the K-1 can microalign images before combining them, allowing hand-held HDR shots to be taken, for best results it’s important to always use a tripod to prevent camera shake from blurring the HDR image, and it doesn’t work very well for moving subjects.

Custom Images

Pentax’s Custom Images, similar to Nikon’s Picture Styles and Canon’s Picture Controls, are preset combinations of different sharpness, contrast, saturation and colour tone settings. You can change the saturation, hue, high/low key, contrast and sharpness for each of the seven options. They are shown below in the following series, which demonstrates the differences.

Digital Filters

The Pentax K-1 Mark II offers nine different Digital Filters, which allow you to quickly apply an artistic effect to a photo before taking it (JPEG images only). They are shown below in the following series, which demonstrates the differences. Note that applying the Digital Filters slows the camera down somewhat, as it has to process the image for a few seconds after it’s taken.

Conclusion

The Pentax K-1 Mark II remains an excellent 35mm full-frame DSLR camera, but it feels more like a stop-gap release rather than a fully-fledged successor to the original K-1.

18 months is quite a long time in the fast-moving world of digital imaging, so the fact that Pentax have only added less than a handful of new features to the K-1 II is rather disappointing, especially for owners of the K-1. We’d hesitate to recommend that those users upgrade to the K-1 II, either by selling their original cameras and buying the new version or by taking advantage of the rather unique upgrade service, as the three key improvements aren’t collectively worth it.

Extending the ISO range to 819200 sounds great on paper, but looks terrible in reality, with the real benefit being a 1-stop improvement in noise performance much lower down the range. Similarly, the AF system is a little snappier and more reliable when tracking moving subjects, but not massively so compared to the original K-1. Finally, the handheld pixel shift mode does allow you to take sharp, high-resolution still images without having to use a tripod, but only with a number of caveats that limit its overall usefulness.

Add the £200 / $200 increase to the RRP of the K-1 II and the reduction in battery life, and we’re left wondering why you’d choose to upgrade to the Pentax K-1 Mark II. For new would-be owners, though, it’s a much more attractive proposition that still holds its own despite the rather modest improvements.
