Going beyond this snapshot of core features and characteristics, what are the differences between the Canon EOS R5 Mark II and the Fujifilm GFX 100S 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 R5 Mark II and the Fujifilm GFX 100S II. The two cameras are presented according to their relative size. Three consecutive views from the front, the top, and the rear side are shown. All width, height and depth measures are rounded to the nearest millimeter.

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Fujifilm GFX 100S II is notably larger (15 percent) than the Canon R5 Mark II. Moreover, the GFX 100S II is markedly heavier (18 percent) than the R5 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 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 battery packs of both cameras can be charged via USB, which can be very convenient when travelling.

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 R5 Mark II was launched at a somewhat lower price (by 14 percent) than the GFX 100S II, which makes it more attractive for photographers on a tight budget. 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

The size of the imaging sensor is a crucial determinant 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. 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 more expensive and lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Canon R5 Mark II features a full frame sensor and the Fujifilm GFX 100S II a medium format sensor. The sensor area in the GFX 100S II is 67 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.0 and 0.79. The sensor in the R5 Mark II has a native 3:2 aspect ratio, while the one in the GFX 100S II offers a 4:3 aspect.

With 101.8MP, the GFX 100S II offers a higher resolution than the R5 Mark II (44.8MP), but the GFX 100S II has smaller individual pixels (pixel pitch of 3.76μm versus 4.39μm for the R5 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 GFX 100S II has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The resolution advantage of the Fujifilm GFX 100S II implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the GFX 100S II for good quality output (200 dots per inch) amounts to 58.2 x 43.7 inches or 147.9 x 110.9 cm, for very good quality (250 dpi) 46.6 x 34.9 inches or 118.3 x 88.8 cm, and for excellent quality (300 dpi) 38.8 x 29.1 inches or 98.6 x 74 cm. The corresponding values for the Canon R5 Mark II are 41 x 27.3 inches or 104 x 69.4 cm for good quality, 32.8 x 21.9 inches or 83.2 x 55.5 cm for very good quality, and 27.3 x 18.2 inches or 69.4 x 46.3 cm for excellent quality prints.

Unlike the R5 Mark II, the GFX 100S II has the capacity to capture high quality composite images (YESMP) 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 R5 Mark II has a native sensitivity range from ISO 100 to ISO 51200, which can be extended to ISO 50-102400. The corresponding ISO settings for the Fujifilm GFX 100S II are ISO 100 to ISO 12800, with the possibility to increase the ISO range to 50-102400.

In terms of underlying technology, the R5 Mark II is build around a CMOS sensor, while the GFX 100S II uses a BSI-CMOS imager. Both cameras use a Bayer filter for capturing RGB colors on a square grid of photosensors. This arrangement is found in most digital cameras.

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. This service is based on lab testing and assigns an overall score to each camera sensor, as well as ratings for dynamic range ("DXO Landscape"), color depth ("DXO Portrait"), and low-light sensitivity ("DXO Sports"). The following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.

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

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, both cameras under consideration feature an 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 R5 Mark II and the Fujifilm GFX 100S 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.

The R5 Mark II writes its imaging data to CFexpress (type B) or SDXC cards, while the GFX 100S II uses SDXC cards. Both cameras feature dual card slots, which can be very useful in case a memory card fails. Moreover, both the R5 Mark II and the GFX 100S II support UHS-II cards, which provide for Ultra High Speed data transfer of up to 312 MB/s, on both slots.

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 R5 Mark II and Fujifilm GFX 100S II and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Both cameras feature a PC Sync terminal to control professional strobe lights, which will be appreciated by studio photographers.

Both the R5 Mark II and the GFX 100S II are recent models that are part of the current product line-up. The GFX 100S II replaced the earlier Fujifilm GFX 100S, while the R5 Mark II followed on from the Canon R5. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Canon and Fujifilm websites.

Review summary

So what conclusions can be drawn? Is the Canon R5 Mark II better than the Fujifilm GFX 100S II or vice versa? Below is a summary of the relative strengths of each of the two contestants.

Arguments in favor of the Canon EOS R5 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 (8k/60p vs 4K/30p).
• More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
• Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/4000s) to freeze action.
• Faster burst: Shoots at higher frequency (12 vs 7 flaps/sec) to capture the decisive moment.
• More compact: Is smaller (138x98mm vs 150x104mm) and thus needs less room in the bag.
• Less heavy: Is lighter (by 137g or 16 percent) and hence easier to carry around.
• More solid recording: Has a full-sized HDMI port for a sturdy connection to an external recorder.
• More affordable: Was introduced into a lower priced segment (14 percent cheaper at launch).

Advantages of the Fujifilm GFX 100S II:

• More detail: Has more megapixels (101.8 vs 44.8MP), which boosts linear resolution by 48%.
• 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.
• Larger viewfinder image: Features a viewfinder with a higher magnification (0.84x vs 0.76x).
• More detailed LCD: Has a higher resolution rear screen (2360k vs 2100k dots).
• Longer lasting: Gets more shots (530 versus 340) out of a single battery charge.

If the count of individual advantages (bullet points above) is taken as a guide, the R5 Mark II emerges as the winner of the contest (9 : 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 before making a decision on a new camera. A professional sports photographer will view the differences between cameras in a way that diverges from the perspective of a street photog, and a person interested in family portraits has distinct needs from a landscape 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 R5 Mark II and the Fujifilm GFX 100S II place the cameras among the top in their class? Find out in the latest Best Mirrorless Interchangeable Lens Camera listing whether the two cameras rank among the cream of the crop.

In any case, while the comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it says little about, for example, the shooting experience and imaging performance of the R5 Mark II and the GFX 100S 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.

Expert reviews

This is why expert reviews are important. The adjacent summary-table relays the overall verdicts of several of the most popular 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.

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. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
