Going beyond this snapshot of core features and characteristics, what are the differences between the Canon EOS R3 and the Fujifilm X-T4? 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 R3 and the Fujifilm X-T4. 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 X-T4 can be obtained in two different colors (black, silver), while the R3 is only available in black.

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Fujifilm X-T4 is considerably smaller (41 percent) than the Canon R3. Moreover, the X-T4 is substantially lighter (40 percent) than the R3. 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.

Concerning battery life, the R3 gets 760 shots out of its Canon LP-E19 battery, while the X-T4 can take 500 images on a single charge of its Fujifilm NP-W235 power pack. As can be seen in the images above, the R3 has a battery grip built in. This facilitates image-taking in portrait orientation and gives it additional battery power. In order to provide similar functionality for the X-T4, Fujifilm provides the VG-XT4 vertical grip as an optional accessory (see here on ebay). The battery packs of both cameras can be charged via USB, which can be very convenient when travelling.

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators.

Any camera decision will naturally be influenced heavily by the price. 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 X-T4 was launched at a markedly lower price (by 72 percent) than the R3, which puts it into a different market segment. 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 associated with larger, more expensive camera bodies and lenses.

Of the two cameras under consideration, the Canon R3 features a full frame sensor and the Fujifilm X-T4 an APS-C sensor. The sensor area in the X-T4 is 58 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.0 and 1.5. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Despite having a smaller sensor, the X-T4 offers a slightly higher resolution of 26 megapixels, compared with 24 MP of the R3. 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 3.76μm versus 6.00μm for the R3). Moreover, it should be noted that the R3 is a somewhat more recent model (by 1 year and 6 months) than the X-T4, and its sensor might have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixels. Coming back to sensor resolution, it should be mentioned that the X-T4 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The Canon EOS R3 has a native sensitivity range from ISO 100 to ISO 51200, which can be extended to ISO 50-204800. The corresponding ISO settings for the Fujifilm X-T4 are ISO 160 to ISO 12800, with the possibility to increase the ISO range to 80-51200.

In terms of underlying technology, the R3 is build around a Stacked BSI-CMOS sensor, while the X-T4 uses a BSI-CMOS imager. Like most digital cameras, the R3 uses a Bayer filter for capturing RGB colors on a square grid of photosensors. In contrast, the X-T4 employs a more randomized X-Trans layout of photosites, which according to Fujifilm helps to minimize moiré.

For many cameras, data on sensor performance has been reported by DXO Mark. 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.

Many modern cameras are not only capable of taking still images, but also of capturing video footage. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the R3 provides a higher video resolution than the X-T4. It can shoot video footage at 6K/60p, while the Fujifilm is limited to 4K/60p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. The two cameras under consideration are similar with respect to both having an electronic viewfinder. However, the one in the R3 offers a substantially higher resolution than the one in the X-T4 (5760k vs 3690k dots). The table below summarizes some of the other core capabilities of the Canon R3 and Fujifilm X-T4 in connection with corresponding information for a sample of similar cameras.

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

One feature that is present on the R3, but is missing on the X-T4 is a top-level LCD. While being, of course, smaller than the rear screen, the control panel conveys some of the essential shooting information and can be convenient for quick and easy settings verification.

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 R3 and the Fujifilm X-T4 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 R3 writes its imaging data to CFexpress (type B) or SDXC cards, while the X-T4 uses SDXC cards. Both cameras feature dual card slots, which can be very useful in case a memory card fails. Moreover, both cameras support UHS-II cards (Ultra High Speed data transfer of up to 312 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 R3 and Fujifilm X-T4 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the R3 has a headphone jack, which is not present on the X-T4 This port makes it possible to attach external headphones and monitor the quality of sound during the recording process.

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

The R3 is a recent model that features in the current product line-up of Canon. In contrast, the X-T4 has been discontinued (but can be found pre-owned on ebay). As a replacement in the same line of cameras, the X-T4 was succeeded by the Fujifilm X-T5. Further information on the features and operation of the R3 and X-T4 can be found, respectively, in the Canon R3 Manual (free pdf) or the online Fujifilm X-T4 Manual.

Review summary

So what is the bottom line? Is there a clear favorite between the Canon R3 and the Fujifilm X-T4? Which camera is better? The listing below highlights the relative strengths of the two models.

Reasons to prefer the Canon EOS R3:

• Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
• Better image quality: Features a larger and more technologically advanced imaging sensor.
• Richer colors: The sensor size advantage translates into images with better, more accurate colors.
• More dynamic range: Larger sensor captures a wider spectrum of light and dark details.
• Better low-light sensitivity: Larger sensor produces good images even in poorly lit environments.
• Better video: Provides higher definition movie capture (6K/60p vs 4K/60p).
• Better sound control: Has a headphone port that enables audio monitoring while recording.
• More detailed viewfinder: Has higher resolution electronic viewfinder (5760k vs 3690k dots).
• Larger viewfinder image: Features a viewfinder with a higher magnification (0.76x vs 0.75x).
• Easier setting verification: Features an LCD display on top to control shooting parameters.
• Larger screen: Has a bigger rear LCD (3.2" vs 3.0") for image review and settings control.
• More detailed LCD: Has a higher resolution rear screen (4150k vs 1620k dots).
• More portrait friendly: Features an integrated vertical grip for easier portrait shooting.
• Longer lasting: Can take more shots (760 versus 500) on a single battery charge.
• Faster data transfer: Supports a more advanced USB protocol (3.2 vs 3.1).
• More modern: Is somewhat more recent (announced 1 year and 6 months after the X-T4).

Advantages of the Fujifilm X-T4:

• Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
• Faster burst: Shoots at higher frequency (15 vs 12 flaps/sec) to capture the decisive moment.
• More compact: Is smaller (135x93mm vs 150x143mm) and will fit more readily into a bag.
• Less heavy: Has a lower weight (by 408g or 40 percent) and is thus easier to take along.
• More affordable: Was introduced into a lower priced category (72 percent cheaper at launch).
• More heavily discounted: Has been on the market for longer (launched in February 2020).

If the number of relative strengths (bullet points above) is taken as a guide, the R3 is the clear winner of the match-up (16 : 6 points). However, the pertinence of the various camera strengths will differ across photographers, so that you might want to weigh individual camera traits according to their importance for your own imaging needs before making a camera decision. 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 R3 and the Fujifilm X-T4 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 R3 and the X-T4 in practical situations. 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 hands-on reviews by experts are important. The table below provides a synthesis of the camera assessments of some of the best known photo-gear 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 above review scores should be interpreted with care, though. The ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. A score, therefore, has to be seen in close connection to the price and market introduction time 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.
