Fujifilm X-A3 versus Fujifilm X100F

The Fujifilm X-A3 and the Fujifilm X100F are two digital cameras that were announced, 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 megapixel.

Body comparison

An illustration of the physical size and weight of the Fujifilm X-A3 and the Fujifilm X100F is provided in the side-by-side display below. Three consecutive views from the front, the top, and the rear side are shown. All size dimensions are rounded to the nearest millimeter. You can also use the toggle button to switch to a percentage comparison if you prefer that the measures are being expressed in relative terms (in this case, the camera on the left – the X-A3 – represents the basis or 100 percent across all the size and weight measures).

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. Cameras intended for semi-professional or professional use tend to be a bit bulkier in order to give them the necessary ruggedness. 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 build 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 find an overview of optics for the X-A3 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 comparisons there.

The listed prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. 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.

Sensor comparison

The size of the imaging sensor is a crucial determinant 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 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.

Sensor size

Even though the X-A3 has a slightly larger sensor, both cameras offer the same resolution of 24 megapixel. This implies that the X-A3 has a lower pixel density and larger individual pixels (with a pixel pitch of 3.92μm versus 3.93μm 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 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.

Consistent information on actual sensor performance is available from DXO Mark for most cameras. 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").

Many modern cameras cannot only take still pictures, but also record videos. 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).

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety 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 table below summarizes some of the other core capabilities of the Fujifilm X-A3 and Fujifilm X100F in connection with corresponding information for a sample of similar cameras. The full specs-sheets can be found in the camera manual or, for example, in the dpreview camera hub.

Both the X-A3 and the X100F are current models that good online retailers will have in stock. You can check the latest prices, for example, at amazon. The X-A3 replaced the earlier Fujifilm X-A2, while the X100F followed on from the Fujifilm X100T.

Summary

So how do things add up? Is there a clear favorite between the Fujifilm X-A3 and the Fujifilm X-A3? A synthesis of the relative strong points of each of the models is listed below.


Reasons to prefer 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 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).

Advantages of the Fujifilm X100F:

  • Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
  • Easier framing: Has an electronic viewfinder for image framing 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 X-A3 comes out slightly ahead of the X100F (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.

X-A3 06:05 X100F

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 handle or 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 why hands-on reviews by experts are important. The following table reports the overall rankings of the cameras as published by some of the major camera review sites. The detailed reviews can be accessed, respectively, on the websites of cameralabs.com, dpreview.com, ephotozine.com, imaging-resource.com, and photographyblog.com.

Care should be taken when interpreting the review scores above, though. The ratings are only valid when refering to cameras in the same category and of the same age. 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. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
