Fujifilm X-A3 vs X100F
The Fujifilm X-A3 and the Fujifilm X100F are two digital cameras that were revealed to the public, respectively, in August 2016 and January 2017. The X-A3 is a mirrorless interchangeable lens camera, while the X100F is a fixed lens compact. Both cameras 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-A3 and the Fujifilm X100F? 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-A3 and the Fujifilm X100F. 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 dimensions are rounded to the nearest millimeter.
The X-A3 can be obtained in three different colors (silver, brown, pink), while the X100F 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 X100F is notably larger (22 percent) than the Fujifilm X-A3. In this context, it is worth noting that neither the X-A3 nor the X100F are weather-sealed.
The above size and weight comparisons are to some extent incomplete and possibly misleading, as the X100F has a lens built in, whereas the X-A3 is an interchangeable lens camera that requires a separate lens. Attaching the latter will add extra weight and bulk to the setup. You can compare the optics available for the X-A3 and their specifications in the Fujinon X Lens Catalog.
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.

The price is, of course, an important factor in any camera decision. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. 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. 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 tend to be associated with larger, more expensive camera bodies and lenses.
Both cameras under consideration feature an APS-C sensor, but their sensors differ slightly in size. 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-A3 has a slightly larger sensor, both cameras offer the same resolution of 24 megapixels. This implies that the X-A3 has a lower pixel density and larger individual pixels (with a pixel pitch of 3.92μm versus 3.92μm for the X100F), which gives it a potential advantage in terms of light gathering capacity. It should, however, be noted that the X100F is a somewhat more recent model (by 4 months) than the X-A3, and its sensor might have benefitted from technological advances during this time that at least partly compensate for the smaller pixel size. Coming back to sensor resolution, it should be mentioned that the X100F has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
The X100F has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.
The Fujifilm X-A3 has a native sensitivity range from ISO 200 to ISO 6400, which can be extended to ISO 100-25600. The corresponding ISO settings for the Fujifilm X100F 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. Like most digital cameras, the X-A3 uses a Bayer filter for capturing RGB colors on a square grid of photosensors. In contrast, the X100F employs a more randomized X-Trans layout of photosites, which according to Fujifilm helps to minimize moiré.
Consistent information on actual sensor performance is available from DXO Mark for many cameras. 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 are not only capable of taking still images, but also of capturing video footage. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, and both provide the same movie specifications (1080/60p).
Apart from body and sensor, cameras can and do differ across a range of features. For example, the X100F has an electronic viewfinder (2360k dots), which can be very helpful when shooting in bright sunlight. In contrast, the X-A3 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-A3, the Fujifilm X100F, and comparable cameras.

|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-A3 has a touchscreen, while the X100F has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.The X-A3 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 X100F 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-A3 and the Fujifilm X100F 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-A3 and the X100F 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-A3 and Fujifilm X100F and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the X100F has a microphone port, which can help to improve the quality of audio recordings by attaching an external microphone. The X-A3 does not feature such a mic input.
Both the X-A3 and the X100F have been discontinued, but can regularly be found used on ebay. The X-A3 was replaced by the Fujifilm X-A5, while the X100F was followed by the Fujifilm X100V. Further information on the features and operation of the X-A3 and X100F can be found, respectively, in the Fujifilm X-A3 Manual (free pdf) or the online Fujifilm X100F Manual.
So what is the bottom line? Is there a clear favorite between the Fujifilm X-A3 and the Fujifilm X100F? Which camera is better? The listing below highlights the relative strengths of the two models.
Arguments in favor of the Fujifilm X-A3:
- Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
- More flexible LCD: Has a tilting screen for odd-angle shots in 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.
- More flexible: Accepts interchangeable lenses, so that lens characteristics can be altered.
- More compact: Is smaller (117x67mm vs 127x75mm) and thus needs less room in the bag.
- More heavily discounted: Has been on the market for longer (launched in August 2016).
Reasons to prefer the Fujifilm X100F:
- Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
- Better live-view autofocus: Features on-sensor phase-detection for more confident autofocus.
- Better sound: Can connect to an external microphone for higher quality sound recording.
- Easier framing: Has an electronic viewfinder for image composition and settings control.
- Faster burst: Shoots at higher frequency (8 vs 6 flaps/sec) to capture the decisive moment.
- Ready to shoot: Has an integrated lens, whereas the X-A3 necessitates an extra lens.
- More modern: Was introduced somewhat (4 months) more recently.
If the count of individual advantages (bullet points above) is taken as a guide, the match-up finishes in a tie (7 points each). 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-A3 and the Fujifilm X100F place the cameras among the top in their class? Find out in the latest Best Mirrorless Interchangeable Lens Camera and Best Prime Lens Compact Camera listings 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-A3 or the X100F 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 where reviews by experts come in. 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 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 rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
