Going beyond this snapshot of core features and characteristics, what are the differences between the Canon EOS M6 Mark II and the Pentax K-3 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.

Body comparison

The side-by-side display below illustrates the physical size and weight of the Canon M6 Mark II and the Pentax K-3 II. The two cameras are presented according to their relative size. Three consecutive perspectives from the front, the top, and the back are available. All size dimensions are rounded to the nearest millimeter.

The K-3 II can be obtained in two different colors (black, silver), while the M6 Mark II is only available in black.

Compare M6 Mark II versus K-3 II top
Comparison M6 Mark II or K-3 II rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Pentax K-3 II is considerably larger (56 percent) than the Canon M6 Mark II. Moreover, the K-3 II is substantially heavier (96 percent) than the M6 Mark II. It is noteworthy in this context that the K-3 II is splash and dust-proof, while the M6 Mark II does not feature any corresponding weather-sealing.

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.

Concerning battery life, the M6 Mark II gets 305 shots out of its LP-E17 battery, while the K-3 II can take 720 images on a single charge of its D-LI90 power pack. The power pack in the M6 Mark II can be charged via the USB port, so that it is not always necessary to take the battery charger along when travelling.

The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives. In case you want to display and compare another camera duo, you can use the CAM-parator app to select your camera combination among a large number of options.

Note: Measurements and pricing do not include easily detachable parts, such as add-on or interchangeable lenses or optional viewfinders.

Any camera decision will naturally be influenced heavily by the price. The manufacturer’s suggested retail prices give an idea on the placement of the camera in the maker’s lineup and the broader market. The M6 Mark II was launched at a somewhat lower price (by 23 percent) than the K-3 II, which makes it more attractive for photographers on a tight budget. Normally, street prices remain initially close to the MSRP, but after a couple of months, the first discounts appear. 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.

Sensor comparison

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 more expensive and lead to bigger and heavier cameras and lenses.

Both cameras under consideration feature an APS-C sensor, but their sensors differ slightly in size. The sensor area in the K-3 II is 9 percent bigger. As a result of these sensor size differences, the cameras have format factors, respectively, of 1.6 (M6 Mark II) and 1.5. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Canon M6 Mark II and Pentax K-3 II sensor measures

Despite having a smaller sensor, the Canon M6 Mark II offers a higher resolution of 32.3 megapixels, compared with 24.1 MP of the Pentax K-3 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 3.23μm versus 3.90μm for the K-3 II). However, it should be noted that the M6 Mark II is much more recent (by 4 years and 4 months) than the K-3 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-3 II has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The resolution advantage of the Canon M6 Mark II implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the M6 Mark II for good quality output (200 dots per inch) amounts to 34.8 x 23.2 inches or 88.4 x 58.9 cm, for very good quality (250 dpi) 27.8 x 18.6 inches or 70.7 x 47.1 cm, and for excellent quality (300 dpi) 23.2 x 15.5 inches or 58.9 x 39.3 cm. The corresponding values for the Pentax K-3 II are 30.1 x 20 inches or 76.4 x 50.8 cm for good quality, 24.1 x 16 inches or 61.1 x 40.6 cm for very good quality, and 20.1 x 13.3 inches or 50.9 x 33.9 cm for excellent quality prints.

The M6 Mark II has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.

Unlike the M6 Mark II, the K-3 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 Canon EOS M6 Mark II has a native sensitivity range from ISO 100 to ISO 25600, which can be extended to ISO 100-51200. The corresponding ISO settings for the Pentax K-3 II are ISO 100 to ISO 51200 (no boost).

Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors. Both cameras use a Bayer filter for capturing RGB colors on a square grid of photosensors. This arrangement is found in most digital cameras.

Many modern cameras are not only capable of taking still images, but can also record movies. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the M6 Mark II provides a higher video resolution than the K-3 II. It can shoot video footage at 4K/30p, while the Pentax is limited to 1080/60i.

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. For example, the K-3 II has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the M6 Mark II relies on live view and the rear LCD for framing. That said, the M6 Mark II can be equipped with an optional viewfinder – the EVF-DC2. The adjacent table lists some of the other core features of the Canon M6 Mark II and Pentax K-3 II along with similar information for a selection of comparators.

Notes: *) Information refers to the mechanical shutter, unless the camera only has an electronic one.

One difference between the cameras concerns the presence of an on-board flash. The M6 Mark II has one, while the K-3 II does not. While the built-in flash of the M6 Mark II is not very powerful, it can at times be useful as a fill-in light.

The M6 Mark II has an articulated LCD that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in snapping selfies. In contrast, the K-3 II does not have a selfie-screen.

The reported shutter speed information refers to the use of the mechanical shutter. Yet, some cameras only have an electronic shutter, while others have an electronic shutter in addition to a mechanical one. In fact, the M6 Mark II is one of those camera that have an additional electronic shutter, which makes completely silent shooting possible. However, this mode is less suitable for photographing moving objects (risk of rolling shutter) or shooting under artificial light sources (risk of flickering).

The Canon M6 Mark II and the Pentax K-3 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 M6 Mark II and the K-3 II write their files to SDXC cards. The K-3 II features dual card slots, which can be very useful in case a memory card fails. In contrast, the M6 Mark II only has one slot. The M6 Mark II supports UHS-II cards (Ultra High Speed data transfer of up to 312 MB/s), while the K-3 II can use UHS-I cards (up to 104 MB/s).

Connectivity comparison

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 Canon EOS M6 Mark II and Pentax K-3 II and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the M6 Mark II offers wifi support, while the K-3 II does not. Wifi can be a very convenient means to transfer image data to an off-camera location.

Studio photographers will appreciate that the Pentax K-3 II (unlike the M6 Mark II) 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-3 II has an internal geolocalization sensor and can record GPS coordinates in its EXIF data.

The M6 Mark II is a recent model that features in the current product line-up of Canon. In contrast, the K-3 II has been discontinued (but can be found pre-owned on ebay). As a replacement in the same line of cameras, the K-3 II was succeeded by the Pentax K-3 III. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Canon and Pentax websites.

If the count of relative strengths (bullet points above) is taken as a measure, the M6 Mark II is the clear winner of the match-up (19 : 15 points). However, the relevance of individual strengths will vary across photographers, so that you might want to apply your own weighing scheme to the summary points when reflecting and deciding 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.

How about other alternatives? Do the specifications of the Canon M6 Mark II and the Pentax K-3 II place the cameras among the top in their class? Find out in the latest Best Mirrorless Interchangeable Lens Camera and Best DSLR Camera listings whether the two cameras rank among the cream of the crop.

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 shooting experience and imaging performance when actually working with the M6 Mark II or the K-3 II. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased.

Expert reviews

This is why expert reviews are important. The following table reports the overall ratings of the cameras as published by some of the major camera review sites (amateurphotographer [AP], cameralabs [CL], digitalcameraworld [DCW], 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.

Notes: (+ +) highly recommended; (+) recommended; (o) reviewed; (..) not available.

Care should be taken when interpreting the review scores above, though. The assessments were made in relation to similar cameras of the same technological generation. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, and comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. Also, please note that some of the review sites have changed their methodology and reporting over time.
