Canon 1Ds Mark III versus Fujifilm GFX 50S

The Canon EOS-1Ds Mark III and the Fujifilm GFX 50S are two professional cameras that were announced, respectively, in August 2007 and September 2016. The 1Ds Mark III is a DSLR, while the GFX 50S is a mirrorless interchangeable lens camera. The cameras are based on a full frame (1Ds Mark III) and a medium format (GFX 50S) sensor. The Canon has a resolution of 21 megapixel, whereas the Fujifilm provides 51.1 MP. Read on to find out how these two cameras compare with respect to their size, their sensors, their features, and their reception by expert reviewers.

Body comparison: Canon 1Ds Mark III vs Fujifilm GFX 50S

The physical size and weight of the Canon 1Ds Mark III and the Fujifilm GFX 50S are illustrated 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 width, height and depth dimensions are rounded to the nearest millimeter. You can also toggle the display to switch to a percentage comparison if you prefer that the measures are being expressed in relative terms (in this case, the camera on the left – the 1Ds Mark III – represents 100 percent across all the size and weight measures).

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Fujifilm GFX 50S is considerably smaller (42 percent) than the Canon 1Ds Mark III. Moreover, the GFX 50S is substantially lighter (47 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 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 50S can take 400 images on a single charge of its NP-T125 power pack.

The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. If you want to switch the focus of the display and review another camera pair, just select a new right or left comparator from among the camera models in the table. Alternatively, you can also move across to the CAM-parator tool and choose from the broad selection of possible camera comparisons there.

Any camera purchase 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 GFX 50S was launched at a somewhat lower price (by 19 percent) than the 1Ds Mark III, 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: Canon 1Ds Mark III vs Fujifilm GFX 50S

The imaging sensor is at the core of digital cameras and its size is one of the main determining factors 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. 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 are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Canon 1Ds Mark III features a full frame sensor and the Fujifilm GFX 50S a medium format sensor. The sensor area in the GFX 50S is 68 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 50S offers a 4:3 aspect.

Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors.

Canon 1Ds Mark III and Fujifilm GFX 50S sensor measures

With 51.1MP, the GFX 50S offers a higher resolution than the 1Ds Mark III (21MP), but the GFX 50S has smaller individual pixels (pixel pitch of 5.33μm versus 6.41μm for the 1Ds Mark III). Yet, the GFX 50S is a much more recent model (by 9 years and 1 month) 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 50S has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

Many modern cameras are not only capable of taking still images, but also of capturing video footage. The GFX 50S indeed provides for movie recording, while the 1Ds Mark III does not. The highest resolution format that the GFX 50S can use is 1080/30p.

 

Feature comparison: Canon 1Ds Mark III vs Fujifilm GFX 50S

Beyond body and sensor, cameras can and do differ across a range of features. For example, the 1Ds Mark III has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the GFX 50S relies on live view and the rear LCD for framing. That said, the GFX 50S can be equipped with an optional viewfinder – the EVF-TL1. The adjacent table lists some of the other core features of the Canon 1Ds Mark III and Fujifilm GFX 50S along with similar information for a selection of comparators.

  • Longer lasting: Can take more shots (1800 versus 400) on a single battery charge.
  • More heavily discounted: Has been available for much longer (launched in August 2007).

ilogo

Advantages of the Fujifilm GFX 50S:

  • More detail: Has more megapixels (51.1 vs 21MP), which boosts linear resolution by 53%.
  • Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
  • Broader imaging potential: Can capture not only stills but also 1080/30p video.
  • More framing options: Can be equipped with a hotshoe-mounted accessory-viewfinder.
  • 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 (2360k vs 230k dots).
  • More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
  • Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
  • More compact: Is smaller (148x94mm vs 150x160mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight (by 645g or 47 percent) and is thus easier to take along.
  • More legacy lens friendly: Can use many non-native lenses via adapters.
  • More affordable: Was released into a lower priced segment (19 percent cheaper at launch).
  • More modern: Reflects 9 years and 1 month of technical progress since the 1Ds Mark III launch.

If the number of relative strengths (bullet points above) is taken as a guide, the GFX 50S is the clear winner of the contest (13 : 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.

1Ds Mark III 06:13 GFX 50S

In any case, while the specs-based evaluation of cameras is instructive in revealing their potential as photographic tools, it remains incomplete and does no justice, for example, to the way the 1Ds Mark III or the GFX 50S handle or perform in practice. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased. This is where reviews by experts come in. The following table reports the overall rankings of the cameras as published by some of the major camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, photographyblog).

Care should be taken when interpreting the review scores above, though. The ratings are only valid when refering to cameras in the same category and of the same age. Hence, a score should always be seen in the context of the camera's market launch date and its price, and comparisons of ratings among very different cameras or across long time periods have little meaning. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
