Fujifilm X-T20 versus Fujifilm X-A3

The Fujifilm X-T20 and the Fujifilm X-A3 are two digital cameras that were revealed to the public, respectively, in January 2017 and August 2016. Both the X-T20 and the X-A3 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-T20 vs Fujifilm X-A3

An illustration of the physical size and weight of the Fujifilm X-T20 and the Fujifilm X-A3 is provided in the side-by-side display below. 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. 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-T20 – 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-A3 is notably smaller (20 percent) than the Fujifilm X-T20. Moreover, the X-A3 is markedly lighter (11 percent) than the X-T20. In this context, it is worth noting that neither the X-T20 nor the X-A3 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 following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. 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 manufacturer’s suggested retail prices give an idea on the placement of the camera in the maker’s lineup and the broader market. 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. 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.

 

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

The imaging sensor is at the core of digital cameras and its size is one of the main determining factors 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, 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.

In terms of underlying technology, both cameras are build around CMOS sensors.

Fujifilm X-T20 and Fujifilm X-A3 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 marginally 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.

X-T20 versus X-A3 MP

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.

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 higher video resolution than the X-A3. It can shoot video footage at 4K/30p, while the X-A3 is limited to 1080/60p.

 

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

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 adjacent table lists some of the other core features of the Fujifilm X-T20 and Fujifilm X-A3 along with similar information for a selection of comparators. If you need more detail on the specs, you can find comprehensive listings, for example, in the dpreview camera hub.

Both the X-T20 and the X-A3 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-T20 vs Fujifilm X-A3

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


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: Is somewhat more recent (announced 4 months after the X-A3).


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 will fit more readily into a bag.
  • Less heavy: Has a lower weight (by 44g or 11 percent) and is thus easier to take along.
  • Longer lasting: Gets more shots (410 versus 350) out of 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).

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 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.

X-T20 05:06 X-A3

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-T20 or the X-A3 handle or perform in practice. 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 where reviews by experts come in.

The review scores listed above should be treated with care, though. The ratings are only valid when refering to cameras in the same category and of the same age. 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.
