Fujifilm X-A2 vs X100S
The Fujifilm X-A2 and the Fujifilm X100S are two digital cameras that were officially introduced, respectively, in January 2015 and January 2013. The X-A2 is a mirrorless interchangeable lens camera, while the X100S is a fixed lens compact. Both cameras are equipped with an APS-C sensor. Both cameras offer a resolution of 16 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-A2 and the Fujifilm X100S? 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-A2 and the Fujifilm X100S is provided in the side-by-side display below. 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 size dimensions are rounded to the nearest millimeter.
The X-A2 can be obtained in three different colors (black, brown, white), while the X100S 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 X100S is notably larger (20 percent) than the Fujifilm X-A2. In this context, it is worth noting that neither the X-A2 nor the X100S are weather-sealed.
The above size and weight comparisons are to some extent incomplete and possibly misleading, as the X100S has a lens built in, whereas the X-A2 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-A2 and their specifications in the Fujinon X Lens Catalog.
The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. If you want to switch the focus of the display and review another camera pair, just select a new right or left comparator from among the camera models in the table. Alternatively, you can also move across to the CAM-parator tool and choose from the broad selection of possible camera comparisons there.

Any camera decision will obviously take relative prices into account. The manufacturer’s suggested retail prices give an idea on the placement of the camera in the maker’s lineup and the broader market. 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 size of the imaging sensor is a crucial determinant of image quality. A large sensor will generally have larger individual pixels that offer better low-light sensitivity, provide wider dynamic range, and have richer color-depth than smaller pixels 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 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 16 megapixels. This similarity in sensor specs implies that both the X-A2 and the X100S have the same pixel density, as well as the same pixel size. It should, however, be noted that the X-A2 is much more recent (by 2 years) than the X100S, and its sensor will have benefitted from technological advances during this time. Coming back to sensor resolution, it should be mentioned that the X100S has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
The X100S has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.
The Fujifilm X-A2 has a native sensitivity range from ISO 200 to ISO 6400, which can be extended to ISO 100-25600. The Fujifilm X100S offers exactly the same ISO settings.
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 following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.
|Leica X Typ 113||APS-C||16.1||4928||3264||1080/30p||..||..||..||..|
|Nikon Coolpix A||APS-C||16.1||4928||3264||1080/30p||23.4||13.8||1164||80|
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, but the X100S provides a faster frame rate than the X-A2. It can shoot movie footage at 1080/60p, while the X-A2 is limited to 1080/30p.
Apart from body and sensor, cameras can and do differ across a range of features. For example, the X100S has an electronic viewfinder (2360k dots), which can be very helpful when shooting in bright sunlight. In contrast, the X-A2 relies on live view and the rear LCD for framing. The table below summarizes some of the other core capabilities of the Fujifilm X-A2 and Fujifilm X100S in connection with corresponding information for a sample of similar cameras.

|Nikon Coolpix A||optional||n||3.0||921||fixed||n||1/2000s||4.0||Y||n|
Concerning the storage of imaging data, both the X-A2 and the X100S 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-A2 and Fujifilm X100S and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

|Leica X Typ 113||Y||stereo||mono||-||-||mini||2.0||-||-||-|
|Nikon Coolpix A||Y||stereo||mono||-||-||-||2.0||-||-||-|
It is notable that the X-A2 offers wifi support, while the X100S does not. Wifi can be a very convenient means to transfer image data to an off-camera location.
Both the X-A2 and the X100S have been discontinued, but can regularly be found used on eBay. The X100S was replaced by the Fujifilm X100T, while the X-A2 was followed by the Fujifilm X-A3. 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 what is the bottom line? Is there a clear favorite between the Fujifilm X-A2 and the Fujifilm X100S? Which camera is better? The listing below highlights the relative strengths of the two models.
Advantages of the Fujifilm X-A2:
- Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
- Larger screen: Has a bigger rear LCD (3.0" vs 2.8") for image review and settings control.
- More detailed LCD: Has a higher resolution rear screen (920k vs 460k dots).
- More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
- 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 127x74mm) and thus needs less room in the bag.
- Longer lasting: Can take more shots (410 versus 330) on a single battery charge.
- Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
- More modern: Reflects 2 years of technical progress since the X100S launch.
Reasons to prefer the Fujifilm X100S:
- Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
- Better video: Provides higher movie framerates (1080/60p versus 1080/30p).
- 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.
- Ready to shoot: Has an integrated lens, whereas the X-A2 necessitates an extra lens.
- More heavily discounted: Has been around for much longer (launched in January 2013).
If the count of individual advantages (bullet points above) is taken as a guide, the X-A2 is the clear winner of the match-up (10 : 6 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 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-A2 and the Fujifilm X100S 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 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-A2 or the X100S perform in practice. 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.
This is where reviews by experts come in. The adjacent summary-table relays the overall verdicts of several of the most popular camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, and photographyblog). 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.

Care should be taken when interpreting the review scores above, 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 comparisons of ratings among very different cameras or across long time periods have little meaning. Also, please note that some of the review sites have changed their methodology and reporting over time.
