Fujifilm X-A5 vs X-T100
The Fujifilm X-A5 and the Fujifilm X-T100 are two digital cameras that were officially introduced, respectively, in January 2018 and May 2018. Both the X-A5 and the X-T100 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 Fujifilm X-T100? 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.
The side-by-side display below illustrates the physical size and weight of the Fujifilm X-A5 and the Fujifilm X-T100. The two cameras are presented according to their relative size. Three consecutive views from the front, the top, and the rear side are shown. 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 X-T100 is also available in three color-versions, but different ones (black, silver, gold).
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Fujifilm X-T100 is notably larger (26 percent) than the Fujifilm X-A5. Moreover, the X-T100 is markedly heavier (24 percent) than the X-A5. In this context, it is worth noting that neither the X-A5 nor the X-T100 are weather-sealed.
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.
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. In case you want to display and compare another camera duo, you can use the CAM-parator app to select your camera combination among a large number of options.

The price is, of course, an important factor in any camera decision. The manufacturer’s suggested retail prices give an idea on the placement of the camera in the maker’s lineup and the broader market. The X-A5 was launched at a markedly lower price (by 33 percent) than the X-T100, 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.
The imaging sensor is at the core of digital cameras and its size is one of the main determining factors 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. Further, a large sensor camera will give the photographer additional creative options when using shallow depth-of-field to isolate a subject from its 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 and have a format factor (sometimes also referred to as "crop factor") of 1.5. Within the spectrum of camera sensors, this places the review cameras among the medium-sized sensor cameras that aim to strike a balance between image quality and portability. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.
The two cameras under review do not only share the same sensor size, but also offer an identical resolution of 24 megapixels. This similarity in sensor specs implies that both the X-A5 and the X-T100 have the same pixel density, as well as the same pixel size. It should, however, be noted that the X-T100 is a somewhat more recent model (by 3 months) than the X-A5, and its sensor might have benefitted from technological advances during this time.
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-T100 are ISO 200 to ISO 12800, with the possibility to increase the ISO range to 100-51200.
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 assesses and scores the color depth ("DXO Portrait"), dynamic range ("DXO Landscape"), and low-light sensitivity ("DXO Sports") of camera sensors, and also publishes an overall camera score. The following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.
|Note: DXO values in italics represent estimates based on sensor size and age.|
Many modern cameras cannot only take still pictures, but also record videos. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, and both provide the same movie specifications (4K/15p).
Apart from body and sensor, cameras can and do differ across a variety of features. For example, the X-T100 has an electronic viewfinder (2360k 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 Fujifilm X-T100, 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 and the Fujifilm X-T100 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-T100 write their files to SDXC 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 Fujifilm X-T100 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Both the X-A5 and the X-T100 have been discontinued, but can regularly be found used on ebay. The X-T100 was replaced by the Fujifilm X-T200, while the X-A5 does not have a direct successor. Further information on the features and operation of the X-A5 and X-T100 can be found, respectively, in the Fujifilm X-A5 Manual (free pdf) or the online Fujifilm X-T100 Manual.
So what conclusions can be drawn? Which of the two cameras – the Fujifilm X-A5 or the Fujifilm X-T100 – has the upper hand? Is one clearly better than the other? A synthesis of the relative strong points of each of the models is listed below.
Arguments in favor of the Fujifilm X-A5:
- More compact: Is smaller (117x68mm vs 121x83mm) and thus needs less room in the bag.
- Less heavy: Is lighter (by 87g or 19 percent) and hence easier to carry around.
- More affordable: Was introduced into a lower priced category (33 percent cheaper at launch).
- More heavily discounted: Has been on the market for longer (launched in January 2018).
Reasons to prefer the Fujifilm X-T100:
- Easier framing: Has an electronic viewfinder for image composition and settings control.
- More flexible LCD: Has a swivel screen for odd-angle shots in portrait or landscape orientation.
- More modern: Was introduced somewhat (3 months) more recently.
If the count of individual advantages (bullet points above) is taken as a guide, the X-A5 comes out slightly ahead of the X-T100 (4 : 3 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 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 Fujifilm X-T100 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 X-A5 or the X-T100 perform in practice. 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], 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. Hence, a score should always be seen in the context of the camera's market launch date and its price, and comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. Also, please note that some of the review sites have changed their methodology and reporting over time.
