Fujifilm X-A3 versus Fujifilm X-T20

The Fujifilm X-A3 and the Fujifilm X-T20 are two digital cameras that were revealed to the public, respectively, in August 2016 and January 2017. Both the X-A3 and the X-T20 are mirrorless interchangeable lens cameras that are equipped with an APS-C sensor. Both cameras offer a resolution of 24 megapixel. Read on to find out how these two cameras compare with respect to their size, their sensors, their features, and their reception by expert reviewers.

Body comparison: Fujifilm X-A3 vs Fujifilm X-T20

The physical size and weight of the Fujifilm X-A3 and the Fujifilm X-T20 are illustrated in the side-by-side display below. The two cameras are presented according to their relative size. Three consecutive perspectives from the front, the top, and the back are available. All width, height and depth measures are rounded to the nearest millimeter. If you prefer, you can also use the toggle button to switch to a comparison in percentage 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 X-T20 is notably larger (25 percent) than the Fujifilm X-A3. Moreover, the X-T20 is markedly heavier (13 percent) than the X-A3. In this context, it is worth noting that neither the X-A3 nor the X-T20 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 find an overview of suitable optics 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 table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. If you would like to visualize and compare a different camera combination, just use the right or left arrows in the table to switch to the respective camera.

The camera’s price is obviously a critical decision-making factor. The retail prices at the time of the camera’s release place the model in the market relative to other models in the producer’s line-up and the competition. The X-A3 was launched at a markedly lower price (by 56 percent) than the X-T20, 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.

 

Sensor comparison: Fujifilm X-A3 vs Fujifilm X-T20

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.

Fujifilm X-A3 and Fujifilm X-T20 sensor measures

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 3.92μm for the X-T20), which gives it a potential advantage in terms of light gathering capacity. It should, however, be noted that the X-T20 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 X-T20 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

Many modern cameras are not only capable of taking still images, but can also record movies. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the X-T20 provides a better video resolution than the X-A3. It can shoot movie footage at 4K/30p, while the X-A3 is limited to 1080/60p.

 

Feature comparison: Fujifilm X-A3 vs Fujifilm X-T20

Beyond body and sensor, cameras can and do differ across a range of features. For example, the X-T20 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 X-T20, and comparable cameras. If needed, the dpreview camera hub, for example, contains further detail on the cameras' specs.

Both the X-A3 and the X-T20 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 X-T20 followed on from the Fujifilm X-T10.

Review summary: Fujifilm X-A3 vs Fujifilm X-T20

So what conclusions can be drawn? Which of the two cameras – the Fujifilm X-A3 or the Fujifilm X-T20 – has the upper hand? Below is a summary of the relative strengths of each of the two contestants.


Reasons to prefer the Fujifilm X-A3:

  • Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
  • More compact: Is smaller (117x67mm vs 118x83mm) and thus needs less room in the bag.
  • Less heavy: Is lighter (by 44g or 11 percent) and hence easier to carry around.
  • Longer lasting: Can take more shots (410 versus 350) on a single battery charge.
  • More affordable: Was introduced into a lower priced category (56 percent cheaper at launch).
  • More heavily discounted: Has been on the market for longer (launched in August 2016).


Arguments in favor of the Fujifilm X-T20:

  • Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
  • Better video: Provides higher definition movie capture (4K/30p vs 1080/60p).
  • 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.
  • More modern: Was introduced somewhat (4 months) more recently.

If the number of relative strengths (bullet points above) is taken as a guide, the X-A3 comes out slightly ahead of the X-T20 (6 : 5 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.

In any case, while the specs-based evaluation of cameras is instructive in revealing their potential as photographic tools, it says nothing about, for example, the handling, responsiveness, and overall imaging quality of the X-A3 and the X-T20 in practical situations. 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 expert reviews are important. The following table reports the overall rankings of the cameras as published by some of the major camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, photographyblog).

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. 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. Also, please note that some of the review sites have changed their methodology and reporting over time.
