Fujifilm X-A5 vs X-T4
The Fujifilm X-A5 and the Fujifilm X-T4 are two digital cameras that were announced, respectively, in January 2018 and February 2020. Both the X-A5 and the X-T4 are mirrorless interchangeable lens cameras that are equipped with an APS-C sensor. The X-A5 has a resolution of 24 megapixels, whereas the X-T4 provides 26 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-A5 and the Fujifilm X-T4? 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 Fujifilm X-T4 is provided 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 size dimensions are rounded to the nearest millimeter.
The X-A5 can be obtained in three different colors (silver, brown, pink), while the X-T4 is available in two color-versions (black, silver).
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Fujifilm X-T4 is considerably larger (58 percent) than the Fujifilm X-A5. Moreover, the X-T4 is substantially heavier (68 percent) than the X-A5. It is noteworthy in this context that the X-T4 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. In this particular case, both cameras feature the same lens mount, so that they can use the same lenses. You can compare the optics available in the Fujinon X Lens Catalog. 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 X-T4 can take 500 images on a single charge of its NP-W235 power pack. The battery packs of both cameras can be charged via USB, which can be very convenient when travelling.
The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. If you would like to visualize and compare a different camera combination, you can navigate to the CAM-parator app and make your selection from a broad list of cameras there.

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-A5 was launched at a markedly lower price (by 77 percent) than the X-T4, which puts it into a different market segment. Normally, street prices remain initially close to the MSRP, but after a couple of months, the first discounts appear. 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.
The size of the sensor inside a digital camera is one of the key determinants 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.
Both cameras under consideration feature an APS-C sensor, but their sensors differ slightly in size. The sensor area in the X-T4 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.
Despite having a slightly smaller sensor, the X-T4 offers a slightly higher resolution of 26 megapixels, compared with 24 MP of the X-A5. 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 3.92μm for the X-A5). However, it should be noted that the X-T4 is much more recent (by 2 years) than the X-A5, 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 X-T4 has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.
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 Fujifilm X-T4 are ISO 160 to ISO 12800, with the possibility to increase the ISO range to 80-51200.
Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. This service is based on lab testing and assigns an overall score to each camera sensor, as well as ratings for dynamic range ("DXO Landscape"), color depth ("DXO Portrait"), and low-light sensitivity ("DXO Sports"). The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

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 X-T4 provides a faster frame rate than the X-A5. It can shoot movie footage at 4K/60p, while the X-A5 is limited to 4K/15p.
Apart from body and sensor, cameras can and do differ across a range of features. For example, the X-T4 has an electronic viewfinder (3690k 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 table below summarizes some of the other core capabilities of the Fujifilm X-A5 and Fujifilm X-T4 in connection with corresponding information for a sample of similar cameras.
One difference between the cameras concerns the presence of an on-board flash. The X-A5 has one, while the X-T4 does not. While the built-in flash of the X-A5 is not very powerful, it can at times be useful as a fill-in light.Both cameras have an articulated rear screen that can be turned to be front-facing. This feature will be particularly appreciated by vloggers and photographers who are interested in taking selfies.
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 and the Fujifilm X-T4 both have 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.
Concerning the storage of imaging data, both the X-A5 and the X-T4 write their files to SDXC cards. The X-T4 features dual card slots, which can be very useful in case a memory card fails. In contrast, the X-A5 only has one slot. The X-T4 supports UHS-II cards (on both slots), while the X-A5 can use UHS-I cards.
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 Fujifilm X-T4 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Studio photographers will appreciate that the Fujifilm X-T4 (unlike the X-A5) 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 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 two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Fujifilm website.
So how do things add up? Is the Fujifilm X-A5 better than the Fujifilm X-T4 or vice versa? The listing below highlights the relative strengths of the two models.
Advantages of the Fujifilm X-A5:
- Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
- More compact: Is smaller (117x68mm vs 135x93mm) and thus needs less room in the bag.
- Less heavy: Is lighter (by 246g or 41 percent) and hence easier to carry around.
- Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
- More affordable: Was introduced into a lower priced category (77 percent cheaper at launch).
- More heavily discounted: Has been available for much longer (launched in January 2018).
Reasons to prefer the Fujifilm X-T4:
- 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/15p).
- Better live-view autofocus: Features on-sensor phase-detection for more confident autofocus.
- Easier framing: Has an electronic viewfinder for image composition and settings control.
- More detailed LCD: Has a higher resolution rear screen (1620k vs 1040k dots).
- More flexible LCD: Has a swivel screen for odd-angle shots in portrait or landscape orientation.
- Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/4000s) to freeze action.
- Faster burst: Shoots at higher frequency (15 vs 6 flaps/sec) to capture the decisive moment.
- Longer lasting: Gets more shots (500 versus 450) out of a single battery charge.
- Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
- Sharper images: Has stabilization technology built-in to reduce the impact of hand-shake.
- Faster data transfer: Supports a more advanced USB protocol (3.1 vs 2.0).
- 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 modern: Reflects 2 years of technical progress since the X-A5 launch.
If the count of individual advantages (bullet points above) is taken as a guide, the X-T4 is the clear winner of the contest (16 : 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. 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 X-A5 and the Fujifilm X-T4 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 says little about, for example, the shooting experience and imaging performance of the X-A5 and the X-T4 in practical situations. At times, user reviews, such as those published at amazon, address these issues in a useful manner, but such feedback is on many occasions incomplete, inconsistent, and unreliable.
This is why expert reviews are important. The table below provides a synthesis of the camera assessments of some of the best known photo-gear review sites (amateurphotographer [AP], cameralabs [CL], 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 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 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.
