Canon 1D X Mark II versus Pentax K-1 II

The Canon EOS-1D X Mark II and the Pentax K-1 II are two digital cameras that were announced, respectively, in February 2016 and February 2018. Both are DSLR (Digital Single Lens Reflex) cameras that are equipped with a full frame sensor. The Canon has a resolution of 20 megapixel, whereas the Pentax provides 36.2 MP. Read on to find out how these two cameras compare with respect to their size, their sensors, their features, and their reception by expert reviewers.

Body comparison: Canon 1D X Mark II vs Pentax K-1 II

The side-by-side display below illustrates the physical size and weight of the Canon 1D X Mark II and the Pentax K-1 II. The two cameras are presented according to their relative size. Three successive views from the front, the top, and the rear are shown. All size dimensions are rounded to the nearest millimeter. You can also toggle the display 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 1DX Mark II – 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 Pentax K-1 II is considerably smaller (43 percent) than the Canon 1D X Mark II. Moreover, the K-1 II is markedly lighter (34 percent) than the 1DX Mark II. 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.

Concerning battery life, the 1DX Mark II gets 1210 shots out of its LP-E19 battery, while the K-1 II can take 670 images on a single charge of its D-LI90 power pack. As can be seen in the images above, the 1DX Mark II has a battery grip build in. This facilitates image-taking in portrait orientation and gives it additional battery power. In order to provide similar functionality for the K-1 II, Pentax provides the D-BG6 vertical grip as an optional accessory (see here on eBay).

The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives. 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 camera comparisons there.

The camera’s price is obviously a critical decision-making factor. The retail prices at the time of the camera’s release place the model in the market relative to other models in the producer’s line-up and the competition. The K-1 II was launched at a markedly lower price (by 67 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.

 

Sensor comparison: Canon 1D X Mark II vs Pentax K-1 II

The imaging sensor is at the core of digital cameras and its size is one of the main determining factors 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. Further, a large sensor camera will give the photographer additional creative options when using shallow depth-of-field to isolate a subject from its background. On the downside, larger sensors tend to be associated with larger, more expensive camera bodies 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.

Canon 1D X Mark II and Pentax K-1 II sensor measures

Despite having a slightly smaller sensor, the K-1 II offers a higher resolution of 36.2 megapixel, compared with 20 MP of the 1DX 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). However, it should be noted that the K-1 II is much more recent (by 2 years) than the 1DX Mark II, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently. Coming back to sensor resolution, it should be mentioned that the K-1 II has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The 1DX Mark II has on-sensor phase detect pixels, which results in relatively fast and reliable autofocus acquisition during video recording.

Unlike the 1DX Mark II, the K-1 II 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).

Consistent information on actual sensor performance is available from DXO Mark for many cameras. 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"). The adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-cameras.

Many modern cameras cannot only take still pictures, but also record videos. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the 1DX Mark II provides a higher video resolution than the K-1 II. It can shoot video footage at 4K/60p, while the Pentax is limited to 1080/60i.

 

Feature comparison: Canon 1D X Mark II vs Pentax K-1 II

Apart from body and sensor, cameras can and do differ across a variety of features. The 1DX Mark II and the K-1 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 adjacent table lists some of the other core features of the Canon 1D X Mark II and Pentax K-1 II along with similar information for a selection of comparators. If needed, the dpreview camera hub, for example, contains further detail on the cameras' specs.

  • 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.
  • More flexible LCD: Has full-flex screen for odd-angle shots in portrait or landscape orientation.
  • More compact: Is smaller (137x110mm vs 158x168mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight (by 520g or 34 percent) and is thus easier to take along.
  • Sharper images: Has stabilization technology build-in to reduce the impact of hand-shake.
  • Easier file upload: Has wifi build in for automatic backup or image transfer to the web.
  • More affordable: Was introduced into a lower priced category (67 percent cheaper at launch).
  • More modern: Reflects 2 years of technical progress since the 1DX Mark II launch.

If the count of individual advantages (bullet points above) is taken as a guide, the match-up finishes in a tie (10 points each). 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 before making a decision on a new camera.

1DX Mark II 10:10 K-1 II

In any case, while the specs-based evaluation of cameras is instructive in revealing their potential as photographic tools, it remains partial and cannot reveal, for example, the handling experience and imaging performance when actually working with the 1DX Mark II or the K-1 II. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased. This is where reviews by experts come in. The adjacent table relays the overall verdicts of several of the most popular camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, photographyblog).

The review scores listed above should be treated 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 comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
