Canon 1D Mark III vs Fujifilm X-T3
The Canon EOS-1D Mark III and the Fujifilm X-T3 are two digital cameras that were revealed to the public, respectively, in February 2007 and September 2018. The 1D Mark III is a DSLR, while the X-T3 is a mirrorless interchangeable lens camera. The cameras are based on an APS-H (1D Mark III) and an APS-C (X-T3) sensor. The Canon has a resolution of 10.1 megapixels, whereas the Fujifilm provides 26 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 Canon EOS-1D Mark III and the Fujifilm X-T3? 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 Canon 1D Mark III and the Fujifilm X-T3 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 size dimensions are rounded to the nearest millimeter.
The X-T3 can be obtained in two different colors (black, silver), while the 1D Mark III 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-T3 is considerably smaller (49 percent) than the Canon 1D Mark III. Moreover, the X-T3 is substantially lighter (53 percent) than the 1D Mark III. 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. A larger imaging sensor will tend to go along with bigger and heavier lenses, although exceptions exist. You can compare the optics available for the two cameras in the Canon EF Lens Catalog (1D Mark III) and the Fujinon X Lens Catalog (X-T3). Mirrorless cameras, such as the X-T3, have moreover the advantage that they can use many lenses from other systems via adapters, as they have a relatively short flange to focal plane distance.
Concerning battery life, the 1D Mark III gets 2200 shots out of its LP-E4 battery, while the X-T3 can take 390 images on a single charge of its NP-W126S power pack. As can be seen in the images above, the 1D Mark III 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-T3, Fujifilm provides the VG-XT3 vertical grip as an optional accessory (see here on eBay). The power pack in the X-T3 can be charged via the USB port, which can be very convenient when travelling.

Any camera decision will naturally be influenced heavily by the price. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The X-T3 was launched at a markedly lower price (by 67 percent) than the 1D Mark III, 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.
The size of the sensor inside a digital camera is one of the key determinants 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.
Of the two cameras under consideration, the Canon 1D Mark III features an APS-H sensor and the Fujifilm X-T3 an APS-C sensor. The sensor area in the X-T3 is 30 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.3 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-T3 offers a higher resolution of 26 megapixels, compared with 10.1 MP of the 1D Mark III. 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 7.21μm for the 1D Mark III). However, it should be noted that the X-T3 is much more recent (by 11 years and 6 months) than the 1D Mark III, 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 X-T3 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
The resolution advantage of the Fujifilm X-T3 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the X-T3 for good quality output (200 dots per inch) amounts to 31.2 x 20.8 inches or 79.2 x 52.8 cm, for very good quality (250 dpi) 25 x 16.6 inches or 63.4 x 42.3 cm, and for excellent quality (300 dpi) 20.8 x 13.9 inches or 52.8 x 35.2 cm. The corresponding values for the Canon 1D Mark III are 19.4 x 13 inches or 49.4 x 32.9 cm for good quality, 15.6 x 10.4 inches or 39.5 x 26.3 cm for very good quality, and 13 x 8.6 inches or 32.9 x 21.9 cm for excellent quality prints.
The X-T3 has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.
The Canon EOS-1D Mark III has a native sensitivity range from ISO 100 to ISO 3200, which can be extended to ISO 50-6400. The corresponding ISO settings for the Fujifilm X-T3 are ISO 160 to ISO 12800, with the possibility to increase the ISO range to 80-51200.
For many cameras, data on sensor performance has been reported by DXO Mark. 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 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 X-T3 indeed provides for movie recording, while the 1D Mark III does not. The highest resolution format that the X-T3 can use is 4K/60p.
Beyond body and sensor, cameras can and do differ across a range of features. For example, the X-T3 has an electronic viewfinder (3690k dots), while the 1D Mark III has an optical one. Both systems have their advantages, with the electronic viewfinder making it possible to project supplementary shooting information into the framing view, whereas the optical viewfinder offers lag-free viewing and a very clear framing image. The viewfinders of both cameras offer the same field of view (100%), but the viewfinder of the X-T3 has a higher magnification than the one of the 1D Mark III (0.75x vs 0.58x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The adjacent table lists some of the other core features of the Canon 1D Mark III and Fujifilm X-T3 along with similar information for a selection of comparators.

One feature that is present on the 1D Mark III, but is missing on the X-T3 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, the X-T3 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 Fujifilm X-T3 has 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 1D Mark III writes its imaging data to Compact Flash or SDHC cards, while the X-T3 uses SDXC cards. Both cameras feature dual card slots, which can be very useful in case a memory card fails. The X-T3 supports UHS-II cards (on both slots), while the 1D Mark III cannot take advantage of Ultra High Speed SD cards.
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-1D Mark III and Fujifilm X-T3 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the X-T3 offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the 1D Mark III does not provide wifi capability.
Both cameras feature a PC Sync terminal to control professional strobe lights, which will be appreciated by studio photographers.
Both the 1D Mark III and the X-T3 have been discontinued, but can regularly be found used on eBay. The 1D Mark III was replaced by the Canon 1D Mark IV, while the X-T3 was followed by the Fujifilm X-T4. 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.
So what is the bottom line? Is the Canon 1D Mark III better than the Fujifilm X-T3 or vice versa? A synthesis of the relative strong points of each of the models is listed below.
Arguments in favor of the Canon EOS-1D Mark III:
- Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.

If the count of relative strengths (bullet points above) is taken as a measure, the X-T3 is the clear winner of the contest (21 : 6 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 wildlife photographer will view the differences between cameras in a way that diverges from the perspective of a family photog, and a person interested in architecture has distinct needs from a sports 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 1D Mark III and the Fujifilm X-T3 place the cameras among the top in their class? Find out in the latest Best DSLR Camera and Best Mirrorless Interchangeable Lens 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 incomplete and does no justice, for example, to the way the 1D Mark III or the X-T3 perform in practice. At times, user reviews, such as those published at amazon, address these issues in a useful manner, but such feedback is on many occasions incomplete, inconsistent, and unreliable.
This is why hands-on reviews by experts are important. The adjacent summary-table relays the overall verdicts of several of the most popular 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 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. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
