Body comparison

The side-by-side display below illustrates the physical size and weight of the Sony A99 II 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 width, height and depth measures are rounded to the nearest millimeter.

Size Sony A99 II vs Fujifilm GFX 100
Compare A99 II versus GFX 100 top
Comparison A99 II 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 considerably larger (51 percent) than the Sony A99 II. Moreover, the GFX 100 is substantially heavier (55 percent) than the A99 II. 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 A99 II gets 490 shots out of its Sony NP-FM500H battery, while the GFX 100 can take 800 images on a single charge of its Fujifilm NP-T125 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. In order to provide similar functionality for the A99 II, Sony provides the VG-C99AM vertical grip as an optional accessory (see here on ebay). The power pack in the GFX 100 can be charged via the USB port, which can be very convenient when travelling.

The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives.

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 A99 II was launched at a markedly lower price (by 68 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.

Sensor comparison

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. 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 Sony A99 II 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 A99 II has a native 3:2 aspect ratio, while the one in the GFX 100 offers a 4:3 aspect.

Sony A99 II and Fujifilm GFX 100 sensor measures

With 101.8MP, the GFX 100 offers a higher resolution than the A99 II (42.2MP), but the GFX 100 has smaller individual pixels (pixel pitch of 3.76μm versus 4.52μm for the A99 II). Yet, the GFX 100 is a much more recent model (by 2 years and 8 months) than the A99 II, 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 neither of the two cameras has an anti-alias filter installed, so they are able to capture all the detail the 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 A99 II are 39.8 x 26.5 inches or 101 x 67.4 cm for good quality, 31.8 x 21.2 inches or 80.8 x 53.9 cm for very good quality, and 26.5 x 17.7 inches or 67.3 x 44.9 cm for excellent quality prints.

The Sony Alpha ALT-A99 II has a native sensitivity range from ISO 100 to ISO 25600, which can be extended to ISO 50-25600. 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.

Technology-wise, both cameras are equipped with BSI-CMOS (Backside Illuminated Complementary Metal–Oxide–Semiconductor) sensors. Both cameras use a Bayer filter for capturing RGB colors on a square grid of photosensors. This arrangement is found in most digital cameras.

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. For example, the A99 II has an electronic viewfinder (2400k dots), which can be very helpful when shooting in bright sunlight. In contrast, the GFX 100 relies on live view and the rear LCD for framing. That said, the GFX 100 can be equipped with an optional viewfinder – the EVF-GFX2. The following table reports on some other key feature differences and similarities of the Sony A99 II, the Fujifilm GFX 100, and comparable cameras.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The GFX 100 has a touchscreen, while the A99 II has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.

The A99 II has an articulated LCD that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in snapping 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 A99 II writes its imaging data to SDXC or Memory Stick PRO Duo 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 A99 II can use UHS-I cards.

Review summary

So what is the bottom line? Is the Sony A99 II better than the Fujifilm GFX 100 or vice versa? The listing below highlights the relative strengths of the two models.

ilogo

Reasons to prefer the Sony Alpha ALT-A99 II:

  • Easier framing: Has an electronic viewfinder for image composition and settings control.
  • More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
  • Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/4000s) to freeze action.
  • Faster burst: Shoots at higher frequency (12 vs 5 flaps/sec) to capture the decisive moment.
  • More compact: Is smaller (143x104mm vs 156x144mm) and thus needs less room in the bag.
  • Less heavy: Is lighter (by 471g or 36 percent) and hence easier to carry around.
  • Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
  • More affordable: Was introduced into a lower priced category (68 percent cheaper at launch).
  • More heavily discounted: Has been available for much longer (launched in September 2016).

ilogo

Arguments in favor of the Fujifilm GFX 100:

  • More detail: Has more megapixels (101.8 vs 42.2MP), which boosts linear resolution by 52%.
  • Better image quality: Is equipped with a larger and more technologically advanced 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.
  • 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 1229k dots).
  • Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
  • Less disturbing: Has an electronic shutter option for completely silent shooting.
  • Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
  • More portrait friendly: Features an integrated vertical grip for easier portrait shooting.
  • Longer lasting: Gets more shots (800 versus 490) out of a single battery charge.
  • Easier travel charging: Can be conveniently charged via its USB port.
  • More legacy lens friendly: Can use many non-native lenses via adapters.
  • Faster data transfer: Supports a more advanced USB protocol (3.1 vs 2.0).
  • Faster buffer clearing: Supports a more advanced SD data transfer standard (UHS-II vs UHS-I).
  • More modern: Reflects 2 years and 8 months of technical progress since the A99 II launch.

If the count of relative strengths (bullet points above) is taken as a measure, the GFX 100 is the clear winner of the contest (17 : 9 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.

A99 II 09:17 GFX 100

How about other alternatives? Do the specifications of the Sony A99 II 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 A99 II or the GFX 100. 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.

Expert reviews

This is why hands-on reviews by experts are important. The following table reports the overall ratings of the cameras as published by some of the major 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.

The review scores listed above should be treated 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. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, and comparisons of ratings among very different cameras or across long time periods have little meaning. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
