Pentax K-1 versus Canon 1D X Mark II
The Pentax K-1 and the Canon EOS-1D X Mark II are two digital cameras that were revealed to the public in February 2016. Both are DSLR (Digital Single Lens Reflex) cameras that are equipped with a full frame sensor. The Pentax has a resolution of 36.2 megapixel, whereas the Canon provides 20 MP.
The side-by-side display below illustrates the physical size and weight of the Pentax K-1 and the Canon 1D X Mark II. Three consecutive views from the front, the top, and the rear side are shown. All width, height and depth dimensions are rounded to the nearest millimeter. You can also use the toggle button to switch to a percentage comparison if you prefer that the measures are being expressed in relative terms (in this case, the camera on the left – the K-1 – represents the basis or 100 percent across all the size and weight measures).
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Canon 1D X Mark II is considerably larger (76 percent) than the Pentax K-1. Moreover, the 1DX Mark II is substantially heavier (51 percent) than the K-1. In this context, it is worth noting that both cameras are splash and dust-proof and can, hence, be used in inclement weather conditions or harsh environments.
The above size and weight comparisons are to some extent incomplete since they do not consider the interchangeable lenses that both of these cameras require. Hence, you might want to study the specifications of available lenses in order to get the full picture of the size and weight of the two camera systems.
The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. If you want to switch the focus of the display and review another camera pair, just select a new right or left comparator from among the camera models in the table. Alternatively, you can also move across to the CAM-parator tool and choose from the broad selection of possible comparisons there.

The listed prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The K-1 was launched at a markedly lower price (by 70 percent) than the 1DX Mark II, which puts it into a different market segment. Usually, retail prices stay at first close to the launch price, but after several months, discounts become available. Later in the product cycle and, in particular, when the replacement model is about to appear, further discounting and stock clearance sales often push the camera price considerably down. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.
The size of the imaging sensor is a crucial determinant of image quality. All other things equal, a large sensor will have larger individual pixel-units that offer better low-light sensitivity, wider dynamic range, and richer color depth than smaller pixels in a sensor of the same technological generation. Moreover, a large sensor camera will give the photographer more control over depth-of-field in the image and, thus, the ability to better isolate a subject from the background. On the downside, larger sensors are more costly to manufacture and tent to lead to bigger and heavier cameras and lenses.
Both cameras under consideration feature a full frame sensor, but their sensors differ slightly in size. They nevertheless have the same format factor of 1.0. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.
Despite having a slightly smaller sensor, the Pentax K-1 offers a higher resolution of 36.2 megapixel, compared with 20 MP of the Canon 1D X Mark II. This megapixel advantage comes at the cost of a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 4.88μm versus 6.57μm for the 1DX Mark II). It is noteworthy in this context that the two cameras were released in close succession, so that their sensors are from the same technological generation. Coming back to sensor resolution, it should be mentioned that the K-1 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
Unlike the 1DX Mark II, the K-1 has the capacity to capture high quality composite images by combining multiple shots after shifting its sensor by miniscule distances. This multi-shot, pixel-shift mode is most suitable for photography of stationary objects (landscapes, studio scenes).
For most cameras, data on sensor performance has been reported by DXO Mark. This service determines an overall sensor rating, as well as sub-scores for low-light sensitivity ("DXO Sports"), dynamic range ("DXO Landscape"), and color depth ("DXO Portrait"). Of the two cameras under review, the K-1 has a notably higher overall DXO score than the 1DX Mark II (overall score 8 points higher), which gives it an advantage in terms of imaging quality. This advantage is based on 1.3 bits higher color depth, 1.1 EV in additional dynamic range, and 0 stops in additional low light sensitivity. The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

Many modern cameras are not only capable of taking still images, but can also record movies. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the 1DX Mark II provides a better video resolution than the K-1. It can shoot movie footage at 4K/60p, while the Pentax is limited to 1080/60i.
Apart from body and sensor, cameras can and do differ across a variety of features. The K-1 and the 1DX Mark II are similar in the sense that both have an optical viewfinder. The latter is useful for getting a clear image for framing even in brightly lit environments. The following table reports on some other key feature differences and similarities of the Pentax K-1, the Canon 1D X Mark II, and comparable cameras. If you need more detail on the specs, you can find comprehensive listings, for example, in the dpreview camera hub.

Both the K-1 and the 1DX Mark II are current models that good online retailers will have in stock. You can check the latest prices, for example, at amazon. The 1DX Mark II replaced the earlier Canon 1DX, while the K-1 does not have a direct predecessor.
So what is the bottom line? Is there a clear favorite between the Pentax K-1 and the Pentax K-1? A synthesis of the relative strong points of each of the models is listed below.
Arguments in favor of the Pentax K-1:
- More detail: Offers more megapixels (36.2 vs 20MP) with a 35% higher linear resolution.
- Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
- High quality composites: Can combine several shots after pixel-shifting its sensor.
- Better image quality: Scores markedly higher (8 points) in the DXO overall assessment.
- Richer colors: Generates images with noticeably better colors (1.3 bits more color depth).
- More dynamic range: Captures a larger spectrum of light and dark details (1.1 EV of extra DR).
- More flexible LCD: Has full-flex screen for odd-angle shots in portrait or landscape orientation.
- More compact: Is smaller (137x110mm vs 158x168mm) and thus needs less room in the bag.
- Less heavy: Is lighter (by 520g or 34 percent) and hence easier to carry around.
- Sharper images: Has hand-shake reducing image stabilization build-in.
- More affordable: Was introduced into a lower priced category (70 percent cheaper at launch).
Reasons to prefer the Canon EOS-1D X Mark II:
- Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
- Better video: Provides higher definition movie capture (4K/60p vs 1080/60i).
- More detailed LCD: Has a higher resolution rear screen (1620k vs 1037k dots).
- Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
- Faster burst: Shoots at higher frequency (16 vs 4.4 flaps/sec) to capture the decisive moment.
- Longer lasting: Gets more shots (1210 versus 760) out of a single battery charge.
If the number of relative strengths (bullet points above) is taken as a guide, the K-1 is the clear winner of the match-up (11 : 6 points). However, the relative importance of the various individual camera aspects will vary according to personal preferences and needs, so that you might like to apply corresponding weights to the particular features.
In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it remains partial and cannot reveal, for example, the handling experience and imaging performance when actually working with the K-1 or the 1DX Mark II. User reviews that are available, for instance, at amazon can sometimes shed light on these issues, but such feedback is all too often partial, inconsistent, and inaccurate. This is why hands-on reviews by experts are important. The following table reports the overall rankings of the cameras as published by some of the major camera review sites. The detailed reviews can be accessed, respectively, on the websites of cameralabs.com, dpreview.com, ephotozine.com, imaging-resource.com, and photographyblog.com.

The above review scores should be interpreted with care, though. The assessments were made in relation to similar cameras of the same technological generation. Hence, a score should always be seen in the context of the camera's market launch date and its price, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, please note that some of the review sites have changed their methodology and reporting over time.
