Body comparison

The physical size and weight of the Fujifilm GFX 100 and the Sony A5100 are illustrated in the side-by-side display below. The two cameras are presented according to their relative size. Three consecutive perspectives from the front, the top, and the back are available. All width, height and depth measures are rounded to the nearest millimeter.

The A5100 can be obtained in two different colors (black, white), while the GFX 100 is only available in black.

Compare GFX 100 versus A5100 top
Comparison GFX 100 or A5100 rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Sony A5100 is considerably smaller (69 percent) than the Fujifilm GFX 100. Moreover, the A5100 is substantially lighter (79 percent) than the GFX 100. It is worth mentioning in this context that the GFX 100 is splash and dust resistant, while the A5100 does not feature any corresponding weather-sealing.

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 GFX 100 gets 800 shots out of its Fujifilm NP-T125 battery, while the A5100 can take 400 images on a single charge of its Sony NP-FW50 power pack. As can be seen in the images above, the GFX 100 has a battery grip built in. This facilitates image-taking in portrait orientation and gives it additional battery power. 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.

Note: Measurements and pricing do not include easily detachable parts, such as add-on or interchangeable lenses or optional viewfinders.

Any camera decision will obviously take relative prices into account. 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 A5100 was launched at a markedly lower price (by 95 percent) than the GFX 100, which puts it into a different market segment. 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. 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 imaging sensor is a crucial determinant 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. 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 more expensive and lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Fujifilm GFX 100 features a medium format sensor and the Sony A5100 an APS-C sensor. The sensor area in the A5100 is 75 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 0.79 and 1.5. The sensor in the GFX 100 has a native 4:3 aspect ratio, while the one in the A5100 offers a 3:2 aspect.

Fujifilm GFX 100 and Sony A5100 sensor measures

With 101.8MP, the GFX 100 offers a higher resolution than the A5100 (24MP), but the GFX 100 has smaller individual pixels (pixel pitch of 3.76μm versus 3.91μm for the A5100). However, the GFX 100 is a much more recent model (by 4 years and 9 months) than the A5100, and its sensor will have benefitted from technological advances during this time that enhance the light gathering capacity of its pixels. 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 Sony A5100 are 30 x 20 inches or 76.2 x 50.8 cm for good quality, 24 x 16 inches or 61 x 40.6 cm for very good quality, and 20 x 13.3 inches or 50.8 x 33.9 cm for excellent quality prints.

The Fujifilm GFX 100 has a native sensitivity range from ISO 100 to ISO 12800, which can be extended to ISO 50-102400. The corresponding ISO settings for the Sony Alpha A5100 are ISO 100 to ISO 25600 (no boost).

In terms of underlying technology, the GFX 100 is build around a BSI-CMOS sensor, while the A5100 uses a 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.

GFX 100 versus A5100 MP

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. The GFX 100 and the A5100 are similar in the sense that neither of the two has a viewfinder. The images are, thus, framed using live view on the rear LCD. That said, the GFX 100 can be equipped with an optional viewfinder – the EVF-GFX2. The table below summarizes some of the other core capabilities of the Fujifilm GFX 100 and Sony A5100 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 GFX 100, but is missing on the A5100 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 A5100 has an articulated screen that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in taking selfies. In contrast, the GFX 100 does not have a selfie-screen.

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 GFX 100 writes its imaging data to SDXC cards, while the A5100 uses SDXC or Memory Stick PRO Duo cards. The GFX 100 features dual card slots, which can be very useful in case a memory card fails. In contrast, the A5100 only has one slot. The GFX 100 supports UHS-II cards (on both slots), while the A5100 can use UHS-I cards.

It is notable that the GFX 100 has a hotshoe, while the A5100 does not. This socket makes it possible to easily attach optional accessories, such as an external flash gun.

Studio photographers will appreciate that the Fujifilm GFX 100 (unlike the A5100) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Both the GFX 100 and the A5100 have been discontinued, but can regularly be found used on ebay. The GFX 100 was replaced by the Fujifilm GFX 100 II, while the A5100 does not have a direct successor. Further information on the features and operation of the GFX 100 and A5100 can be found, respectively, in the Fujifilm GFX 100 Manual (free pdf) or the online Sony A5100 Manual.

If the count of relative strengths (bullet points above) is taken as a measure, the GFX 100 is the clear winner of the match-up (27 : 9 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 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 Fujifilm GFX 100 and the Sony A5100 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 remains incomplete and does no justice, for example, to the way the GFX 100 or the A5100 perform in practice. 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.

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.

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

The review scores listed above should be treated with care, though. The ratings are only valid when referring to cameras in the same category and of the same age. 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. Also, please note that some of the review sites have changed their methodology and reporting over time.
