Leica M10-R vs Pentax K-1 II
The Leica M10-R and the Pentax K-1 II are two enthusiast cameras that were officially introduced, respectively, in July 2020 and February 2018. The M10-R is a rangefinder-style mirrorless camera, while the K-1 II is a DSLR. Both cameras are equipped with a full frame sensor. The Leica has a resolution of 40.9 megapixels, whereas the Pentax provides 36.2 MP.
Below is an overview of the main specs of the two cameras as a starting point for the comparison.
Going beyond this snapshot of core features and characteristics, what are the differences between the Leica M10-R and the Pentax K-1 II? Which one should you buy? Read on to find out how these two cameras compare with respect to their body size, their imaging sensors, their shooting features, their input-output connections, and their reception by expert reviewers.
An illustration of the physical size and weight of the Leica M10-R and the Pentax K-1 II is provided in the side-by-side display below. The two cameras are presented according to their relative size. Three successive views from the front, the top, and the rear are shown. All width, height and depth measures are rounded to the nearest millimeter.
Both cameras are available in two different colors (black, silver).
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 notably larger (36 percent) than the Leica M10-R. Moreover, the K-1 II is substantially heavier (53 percent) than the M10-R. 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 and compare the specifications of available lenses in order to get the full picture of the size and weight of the two camera systems.
The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. If you would like to visualize and compare a different camera combination, you can navigate to the CAM-parator app and make your selection from a broad list of cameras there.

The price is, of course, an important factor in any camera decision. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The K-1 II was launched at a markedly lower price (by 76 percent) than the M10-R, 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.
The size of the sensor inside a digital camera is one of the key determinants of image quality. A large sensor will generally have larger individual pixels that offer better low-light sensitivity, provide wider dynamic range, and have 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 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. The sensor area in the K-1 II is 1 percent bigger. 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 Leica M10-R offers a higher resolution of 40.9 megapixels, compared with 36.2 MP of the Pentax K-1 II. This megapixels advantage comes at the cost of a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 4.57μm versus 4.88μm for the K-1 II). However, it should be noted that the M10-R is much more recent (by 2 years and 4 months) than the K-1 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 neither of the two cameras has an anti-alias filter installed, so they are able to capture all the detail the sensor resolves.
The resolution advantage of the Leica M10-R implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the M10-R for good quality output (200 dots per inch) amounts to 39.3 x 26 inches or 99.9 x 66 cm, for very good quality (250 dpi) 31.5 x 20.8 inches or 79.9 x 52.8 cm, and for excellent quality (300 dpi) 26.2 x 17.3 inches or 66.6 x 44 cm. The corresponding values for the Pentax K-1 II are 36.8 x 24.6 inches or 93.5 x 62.4 cm for good quality, 29.4 x 19.6 inches or 74.8 x 49.9 cm for very good quality, and 24.5 x 16.4 inches or 62.3 x 41.6 cm for excellent quality prints.
Unlike the M10-R, 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).
The Leica M10-R has a native sensitivity range from ISO 100 to ISO 50000. The corresponding ISO settings for the Pentax K-1 II are ISO 100 to ISO 819200 (no boost).
Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. This service assesses and scores the color depth ("DXO Portrait"), dynamic range ("DXO Landscape"), and low-light sensitivity ("DXO Sports") of camera sensors, and also publishes an overall camera score. The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

Many modern cameras cannot only take still pictures, but also record videos. The K-1 II indeed provides for movie recording, while the M10-R does not. The highest resolution format that the K-1 II can use is 1080/60i.
Apart from body and sensor, cameras can and do differ across a range of features. The M10-R 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 viewfinders of both cameras offer the same field of view (100%), but the viewfinder of the M10-R has a higher magnification than the one of the K-1 II (0.73x vs 0.70x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The following table reports on some other key feature differences and similarities of the Leica M10-R, the Pentax K-1 II, and comparable cameras.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The M10-R has a touchscreen, while the K-1 II has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.
The Leica M10-R and the Pentax K-1 II both have an intervalometer built-in. This enables the photographer to capture time lapse sequences, such as flower blooming, a sunset or moon rise, without purchasing an external camera trigger and related software.
Concerning the storage of imaging data, both the M10-R and the K-1 II write their files to SDXC cards. The K-1 II features dual card slots, which can be very useful in case a memory card fails. In contrast, the M10-R only has one slot. Both cameras can use UHS-I cards, which provide for Ultra High Speed data transfer of up to 104 MB/s.
For some imaging applications, the extent to which a camera can communicate with its environment can be an important aspect in the camera decision process. The table below provides an overview of the connectivity of the Leica M10-R and Pentax K-1 II and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Studio photographers will appreciate that the Pentax K-1 II (unlike the M10-R) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.
Travel and landscape photographers will find it useful that the K-1 II has an internal geolocalization sensor and can record GPS coordinates in its EXIF data.
Both the M10-R and the K-1 II are recent models that are part of the current product line-up. The K-1 II replaced the earlier Pentax K-1, while the M10-R does not have a direct predecessor. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Leica and Pentax websites.
So what is the bottom line? Is there a clear favorite between the Leica M10-R and the Pentax K-1 II? Which camera is better? A synthesis of the relative strong points of each of the models is listed below.
Reasons to prefer the Leica M10-R:
- More detail: Offers more megapixels (40.9 vs 36.2MP) with a 7% higher linear resolution.
- Larger viewfinder image: Features a viewfinder with a higher magnification (0.73x vs 0.70x).
- Fewer buttons to press: Is equipped with a touch-sensitive rear screen to facilitate handling.
- More compact: Is smaller (139x80mm vs 137x110mm) and thus needs less room in the bag.
- Less heavy: Is lighter (by 350g or 35 percent) and hence easier to carry around.
- More prestigious: Has the Leica luxury appeal, which ensures a high resale price.
- More modern: Reflects 2 years and 4 months of technical progress since the K-1 II launch.
Arguments in favor of the Pentax K-1 II:
- High quality composites: Can combine several shots after pixel-shifting its sensor.
- Broader imaging potential: Can capture not only stills but also 1080/60i video.
- Easier setting verification: Features a control panel on top to check shooting parameters.
- Larger screen: Has a bigger rear LCD (3.2" vs 3.0") for image review and settings control.
- More flexible LCD: Has a full-flex screen for odd-angle shots in portrait or landscape orientation.
- Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/4000s) to freeze action.
- Longer lasting: Gets more shots (670 versus 210) out of a single battery charge.
- Sharper images: Has stabilization technology built-in to reduce the impact of hand-shake.
- Easier geotagging: Features an internal GPS sensor to log localization data.
- Better studio light control: Has a PC Sync socket to connect to professional strobe lights.
- Greater peace of mind: Features a second card slot as a backup in case of memory card failure.
- More affordable: Was introduced into a lower priced category (76 percent cheaper at launch).
- More heavily discounted: Has been around for much longer (launched in February 2018).
If the count of individual advantages (bullet points above) is taken as a guide, the K-1 II is the clear winner of the contest (13 : 7 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 before making a decision on a new camera. A professional wedding photographer will view the differences between cameras in a way that diverges from the perspective of a travel photog, and a person interested in cityscapes has distinct needs from a macro shooter. Hence, the decision which camera is best and worth buying is often a very personal one.
In any case, while the specs-based evaluation of cameras can be instructive in revealing their potential as photographic tools, it says little about, for example, the shooting experience and imaging performance of the M10-R and the K-1 II in practical situations. 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 where reviews by experts come in. The following table reports the overall ratings of the cameras as published by some of the major camera review sites (amateurphotographer [AP], cameralabs [CL], dpreview [DPR], ephotozine [EPZ], photographyblog [PB]). As can be seen, the professional reviewers agree in many cases on the quality of different cameras, but sometimes their assessments diverge, reinforcing the earlier point that a camera decision is often a very personal choice.

Care should be taken when interpreting the review scores above, though. The ratings are only valid when referring to cameras in the same category and of the same age. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, and comparisons of ratings among very different cameras or across long time periods have little meaning. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
