Going beyond this snapshot of core features and characteristics, what are the differences between the Canon EOS-1Ds Mark III and the Fujifilm GFX 100? 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 1Ds Mark III and the Fujifilm GFX 100. 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.

Size Canon 1Ds Mark III vs Fujifilm GFX 100
Compare 1Ds Mark III versus GFX 100 top
Comparison 1Ds Mark III or GFX 100 rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Fujifilm GFX 100 is notably smaller (6 percent) than the Canon 1Ds Mark III. Moreover, the GFX 100 is markedly lighter (5 percent) than the 1Ds 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. 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 1Ds Mark III gets 1800 shots out of its LP-E4 battery, while the GFX 100 can take 800 images on a single charge of its NP-T125 power pack. As can be seen in the images above, both cameras have a battery grip built in. This facilitates image-taking in portrait orientation and gives it additional battery power. The power pack in the GFX 100 can be charged via the USB port, 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. 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.

The price is, of course, an important factor in any camera decision. 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 1Ds Mark III was launched at a somewhat lower price (by 20 percent) than the GFX 100, 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 sensor inside a digital camera is one of the key determinants of image quality. A large sensor will tend to have larger individual pixels that provide better low-light sensitivity, wider dynamic range, and richer color-depth than smaller pixel-units in a sensor of the same technological generation. Furthermore, a large sensor camera will give the photographer more possibilities to use shallow depth-of-field in order to 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 1Ds Mark III features a full frame sensor and the Fujifilm GFX 100 a medium format sensor. The sensor area in the GFX 100 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 1Ds Mark III has a native 3:2 aspect ratio, while the one in the GFX 100 offers a 4:3 aspect.

Canon 1Ds Mark III and Fujifilm GFX 100 sensor measures

With 101.8MP, the GFX 100 offers a higher resolution than the 1Ds Mark III (21MP), but the GFX 100 has smaller individual pixels (pixel pitch of 3.76μm versus 6.41μm for the 1Ds Mark III). Yet, the GFX 100 is a much more recent model (by 11 years and 9 months) than the 1Ds Mark III, and its sensor will have benefitted from technological advances during this time that enhance the light gathering capacity of its pixel-units. Coming back to sensor resolution, it should be mentioned that the GFX 100 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The resolution advantage of the Fujifilm GFX 100 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the GFX 100 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 1Ds Mark III are 28.1 x 18.7 inches or 71.3 x 47.5 cm for good quality, 22.5 x 15 inches or 57.1 x 38 cm for very good quality, and 18.7 x 12.5 inches or 47.5 x 31.7 cm for excellent quality prints.

The GFX 100 has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.

The Canon EOS-1Ds Mark III has a native sensitivity range from ISO 100 to ISO 1600, which can be extended to ISO 50-3200. The corresponding ISO settings for the Fujifilm GFX 100 are ISO 100 to ISO 12800, with the possibility to increase the ISO range to 50-102400.

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

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The GFX 100 has a touchscreen, while the 1Ds Mark III has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.

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 GFX 100 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 GFX 100 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 1Ds Mark III writes its imaging data to Compact Flash or SDHC cards, while the GFX 100 uses SDXC cards. Both cameras feature dual card slots, which can be very useful in case a memory card fails. The GFX 100 supports UHS-II cards (on both slots), while the 1Ds Mark III cannot take advantage of Ultra High Speed SD cards.

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-1Ds Mark III and Fujifilm GFX 100 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the GFX 100 offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the 1Ds 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.

The GFX 100 is a recent model that features in the current product line-up of Fujifilm. In contrast, the 1Ds Mark III has been discontinued (but can be found pre-owned on eBay). As a replacement in the same line of cameras, the 1Ds Mark III was succeeded by the Canon 1DX. 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.

If the count of relative strengths (bullet points above) is taken as a measure, the GFX 100 is the clear winner of the contest (22 : 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 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.

1Ds Mark III 06:22 GFX 100

How about other alternatives? Do the specifications of the Canon 1Ds Mark III and the Fujifilm GFX 100 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 specs-based evaluation of cameras can be instructive in revealing their potential as photographic tools, it remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the 1Ds Mark III or the GFX 100. 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.

Expert reviews

This is where reviews by experts come in. 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.

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

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. Hence, a score should always be seen in the context of the camera's market launch date and its price, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, please note that some of the review sites have changed their methodology and reporting over time.
