Fujifilm X-A5 vs Sony A6400
The Fujifilm X-A5 and the Sony Alpha A6400 are two digital cameras that were announced, respectively, in January 2018 and January 2019. Both the X-A5 and the A6400 are mirrorless interchangeable lens cameras that are equipped with an APS-C sensor. Both cameras offer a resolution of 24 megapixels.
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-A5 and the Sony Alpha A6400? 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.
An illustration of the physical size and weight of the Fujifilm X-A5 and the Sony A6400 is provided 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 X-A5 can be obtained in three different colors (silver, brown, pink), while the A6400 is only available in black.
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Sony A6400 is somewhat larger (1 percent) than the Fujifilm X-A5. Moreover, the A6400 is markedly heavier (12 percent) than the X-A5. It is noteworthy in this context that the A6400 is splash and dust-proof, while the X-A5 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. Yet, since both cameras are based around an APS-C sensor, their respective lenses will tend to have similar dimensions and heft. You can compare the optics available for the two cameras in the Fujinon X Lens Catalog (X-A5) and the Sony E-Mount Lens Catalog (A6400). 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-A5 gets 450 shots out of its NP-W126S battery, while the A6400 can take 410 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.

Any camera decision will naturally be influenced heavily by the price. 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 X-A5 was launched at a markedly lower price (by 56 percent) than the A6400, 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.
The size of the imaging sensor is a crucial determinant of image quality. All other things equal, a large sensor will have larger individual pixel-units that offer better low-light sensitivity, wider dynamic range, and richer color-depth than smaller pixels 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 are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.
Both cameras under consideration feature an APS-C sensor, but their sensors differ slightly in size. The sensor area in the A6400 is 1 percent smaller. They nevertheless have the same format factor of 1.5. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.
Even though the X-A5 has a slightly larger sensor, both cameras offer the same resolution of 24 megapixels. This implies that the X-A5 has a lower pixel density and larger individual pixels (with a pixel pitch of 3.92μm versus 3.91μm for the A6400), which gives it a potential advantage in terms of light gathering capacity. It should, however, be noted that the A6400 is a somewhat more recent model (by 11 months) than the X-A5, and its sensor might have benefitted from technological advances during this time that at least partly compensate for the smaller pixel size.
The Fujifilm X-A5 has a native sensitivity range from ISO 200 to ISO 12800, which can be extended to ISO 200-51200. The corresponding ISO settings for the Sony Alpha A6400 are ISO 100 to ISO 32000, with the possibility to increase the ISO range to 100-102400.
Technology-wise, both cameras are equipped with CMOS (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.
Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. This service determines an overall sensor rating, as well as sub-scores for low-light sensitivity ("DXO Sports"), dynamic range ("DXO Landscape"), and color depth ("DXO Portrait"). The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.
|Note: DXO values in italics represent estimates based on sensor size and age.|
Many modern cameras are not only capable of taking still images, but also of capturing video footage. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, but the A6400 provides a faster frame rate than the X-A5. It can shoot movie footage at 4K/30p, while the Fujifilm is limited to 4K/15p.
Apart from body and sensor, cameras can and do differ across a range of features. For example, the A6400 has an electronic viewfinder (2359k dots), which can be very helpful when shooting in bright sunlight. In contrast, the X-A5 relies on live view and the rear LCD for framing. The following table reports on some other key feature differences and similarities of the Fujifilm X-A5, the Sony A6400, and comparable cameras.

|Notes: *) Information refers to the mechanical shutter, unless the camera only has an electronic one.|
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-A5 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-A5 writes its imaging data to SDXC cards, while the A6400 uses SDXC or Memory Stick PRO Duo cards. Both cameras can use UHS-I cards, which provide for Ultra High Speed data transfer of up to 104 MB/s.
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-A5 and Sony Alpha A6400 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

The A6400 is a recent model that features in the current product line-up of Sony. In contrast, the X-A5 has been discontinued (but can be found pre-owned on ebay). There has not been a direct replacement model for the X-A5 from Fujifilm. Further information on the features and operation of the X-A5 and A6400 can be found, respectively, in the Fujifilm X-A5 Manual (free pdf) or the online Sony A6400 Manual.
So how do things add up? Which of the two cameras – the Fujifilm X-A5 or the Sony A6400 – has the upper hand? Is one clearly better than the other? Below is a summary of the relative strengths of each of the two contestants.
Arguments in favor of the Fujifilm X-A5:
- More detailed LCD: Has a higher resolution rear screen (1040k vs 922k dots).
- Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
- Less heavy: Is lighter (by 42g or 10 percent) and hence easier to carry around.
- More affordable: Was introduced into a lower priced category (56 percent cheaper at launch).
- More heavily discounted: Has been on the market for longer (launched in January 2018).
Reasons to prefer the Sony Alpha A6400:
- Better video: Provides higher movie framerates (4K/30p versus 4K/15p).
- Easier framing: Has an electronic viewfinder for image composition and settings control.
- Faster burst: Shoots at higher frequency (11 vs 6 flaps/sec) to capture the decisive moment.
- Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
- Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
- More modern: Was introduced somewhat (11 months) more recently.
If the count of relative strengths (bullet points above) is taken as a measure, the A6400 comes out slightly ahead of the X-A5 (6 : 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.
How about other alternatives? Do the specifications of the Fujifilm X-A5 and the Sony A6400 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 the spec-sheets of cameras can offer a general idea of their imaging potential, it remains incomplete and does no justice, for example, to the way the X-A5 or the A6400 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 why expert reviews 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 above review scores should be interpreted with care, though. The assessments were made in relation to similar cameras of the same technological generation. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, and comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
