Fujifilm X-T4 vs Sony A7S II

The Fujifilm X-T4 and the Sony Alpha 7S II are two digital cameras that were announced, respectively, in February 2020 and September 2015. Both the X-T4 and the A7S II are mirrorless interchangeable lens cameras that are based on an APS-C (X-T4) and a full frame (A7S II) sensor. The Fujifilm has a resolution of 26 megapixels, whereas the Sony provides 12 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 Fujifilm X-T4 and the Sony Alpha 7S II? 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 Fujifilm X-T4 and the Sony A7S II. 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-T4 can be obtained in two different colors (black, silver), while the A7S II is only available in black.

Size Fujifilm X-T4 vs Sony A7S II
Compare X-T4 versus A7S II top
Comparison X-T4 or A7S II rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Sony A7S II is somewhat smaller (3 percent) than the Fujifilm X-T4. However, the A7S II is slightly heavier (3 percent) than the X-T4. 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 Fujinon X Lens Catalog (X-T4) and the Sony FE Lens Catalog (A7S II). Mirrorless cameras, such as the two under consideration, have the additional advantage of having a short flange to focal plane distance, which makes it possible to mount many lenses from other systems onto the camera via adapters.

Concerning battery life, the X-T4 gets 500 shots out of its NP-W235 battery, while the A7S II can take 370 images on a single charge of its NP-FW50 power pack. The battery packs of both cameras can be charged via USB, 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.

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

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-T4 was launched at a markedly lower price (by 43 percent) than the A7S II, 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 are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Fujifilm X-T4 features an APS-C sensor and the Sony A7S II a full frame sensor. The sensor area in the A7S II is 131 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.5 and 1.0. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Fujifilm X-T4 and Sony A7S II sensor measures

Despite having a smaller sensor, the Fujifilm X-T4 offers a higher resolution of 26 megapixels, compared with 12 MP of the Sony A7S II. 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 8.40μm for the A7S II). However, it should be noted that the X-T4 is much more recent (by 4 years and 5 months) than the A7S II, 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-T4 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The resolution advantage of the Fujifilm X-T4 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the X-T4 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 Sony A7S II are 21.2 x 14.2 inches or 53.8 x 36 cm for good quality, 17 x 11.3 inches or 43.1 x 28.8 cm for very good quality, and 14.1 x 9.4 inches or 35.9 x 24 cm for excellent quality prints.

The X-T4 has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.

The Fujifilm X-T4 has a native sensitivity range from ISO 160 to ISO 12800, which can be extended to ISO 80-51200. The corresponding ISO settings for the Sony Alpha 7S II are ISO 100 to ISO 102400, with the possibility to increase the ISO range to 50-409600.

In terms of underlying technology, the X-T4 is build around a BSI-CMOS sensor, while the A7S II uses a CMOS imager. The X-T4 uses Fujifilm's X-Trans layout of photosites, while the A7S II employs the more common Bayer array.

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 X-T4 has a touchscreen, while the A7S II has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.

The X-T4 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 A7S II 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, both cameras under consideration feature an 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-T4 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 X-T4 writes its imaging data to SDXC cards, while the A7S II uses SDXC or Memory Stick PRO Duo cards. The X-T4 features dual card slots, which can be very useful in case a memory card fails. In contrast, the A7S II only has one slot. The X-T4 supports UHS-II cards (on both slots), while the A7S II can use UHS-I 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 Fujifilm X-T4 and Sony Alpha 7S II and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the A7S II has a headphone jack, which makes it possible to attach external headphones and monitor the quality of sound during the recording process. The X-T4 lacks such a headphone port.

Studio photographers will appreciate that the Fujifilm X-T4 (unlike the A7S II) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

The X-T4 is a recent model that features in the current product line-up of Fujifilm. In contrast, the A7S II has been discontinued (but can be found pre-owned on ebay). As a replacement in the same line of cameras, the A7S II was succeeded by the Sony A7S III. Further information on the features and operation of the X-T4 and A7S II can be found, respectively, in the Fujifilm X-T4 Manual (free pdf) or the online Sony A7S II Manual.

Review summary

So what is the bottom line? Is the Fujifilm X-T4 better than the Sony A7S II or vice versa? The listing below highlights the relative strengths of the two models.

ilogo

Reasons to prefer the Fujifilm X-T4:

  • More detail: Offers more megapixels (26 vs 12MP) with a 47% higher linear resolution.
  • Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
  • Better video: Provides higher movie framerates (4K/60p versus 4K/30p).
  • Better live-view autofocus: Features on-sensor phase-detection for more confident autofocus.
  • More detailed viewfinder: Has higher resolution electronic viewfinder (3690k vs 2400k dots).
  • More detailed LCD: Has a higher resolution rear screen (1620k vs 1229k dots).
  • More flexible LCD: Has a swivel screen for odd-angle shots in portrait or landscape orientation.
  • Fewer buttons to press: Is equipped with a touch-sensitive rear screen to facilitate handling.
  • More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
  • Faster burst: Shoots at higher frequency (15 vs 5 flaps/sec) to capture the decisive moment.
  • Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
  • Longer lasting: Can take more shots (500 versus 370) on a single battery charge.
  • Faster data transfer: Supports a more advanced USB protocol (3.1 vs 2.0).
  • Easier wireless transfer: Supports Bluetooth for image sharing without cables.
  • Better studio light control: Has a PC Sync socket to connect to professional strobe lights.
  • Greater peace of mind: Features a second card slot as a backup in case of memory card failure.
  • Faster buffer clearing: Supports a more advanced SD data transfer standard (UHS-II vs UHS-I).
  • More affordable: Was introduced into a lower priced category (43 percent cheaper at launch).
  • More modern: Reflects 4 years and 5 months of technical progress since the A7S II launch.

ilogo

Arguments in favor of the Sony Alpha 7S II:

  • Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
  • Better sound control: Has a headphone port that enables audio monitoring while recording.
  • Larger viewfinder image: Features a viewfinder with a higher magnification (0.78x vs 0.75x).
  • Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
  • More heavily discounted: Has been around for much longer (launched in September 2015).

If the count of relative strengths (bullet points above) is taken as a measure, the X-T4 is the clear winner of the match-up (19 : 5 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.

X-T4 19:05 A7S II

How about other alternatives? Do the specifications of the Fujifilm X-T4 and the Sony A7S II 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 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 X-T4 or the A7S II. 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.

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

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 rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
