Fujifilm X-A3 versus Fujifilm X-T20

The Fujifilm X-A3 and the Fujifilm X-T20 are two digital cameras that were announced, 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

An illustration of the physical size and weight of the Fujifilm X-A3 and the Fujifilm X-T20 is provided in the side-by-side display below. Three consecutive views from the front, the top, and the rear side are shown. All width, height and depth 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 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 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.

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. 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 imaging sensor is a crucial determinant 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, 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 also of capturing video footage. 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

Apart from 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 adjacent table lists some of the other core features of the Fujifilm X-A3 and Fujifilm X-T20 along with similar information for a selection of comparators. 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? Is the Fujifilm X-A3 better than the Fujifilm X-T20 or vice versa? Below is a summary of the relative strengths of each of the two contestants.


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 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).

Advantages 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 count of individual advantages (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.

X-A3 06:05 X-T20

In any case, while the comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it says nothing about, for example, the handling, responsiveness, and overall imaging quality of the X-A3 and the X-T20 in practical situations. 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 review scores listed above should be treated with care, though. The ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, 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.
