Fujifilm X-T20 versus Sony RX1

The Fujifilm X-T20 and the Sony Cyber-shot DSC-RX1 are two digital cameras that were officially introduced, respectively, in January 2017 and September 2012. The X-T20 is a mirrorless interchangeable lens camera, while the RX1 is a fixed lens compact. The cameras are based on an APS-C (X-T20) and a full frame sensor. Both cameras offer a resolution of 24 megapixel.

Body comparison

An illustration of the physical size and weight of the Fujifilm X-T20 and the Sony RX1 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 measures are rounded to the nearest millimeter. You can also toggle the display 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-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 Sony RX1 is notably smaller (25 percent) than the Fujifilm X-T20. In this context, it is worth noting that neither the X-T20 nor the RX1 are weather-sealed.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the RX1 has a lens build in, whereas the X-T20 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-T20 and their specifications in the Fujinon X Lens Catalog.

Concerning battery life, the X-T20 gets 350 shots out of its NP-W126S battery, while the RX1 can take 270 images on a single charge of its NP-BX1 power pack.

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 sensor inside a digital camera is one of the key determinants 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. 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 more expensive and lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Fujifilm X-T20 features an APS-C sensor and the Sony RX1 a full frame sensor. The sensor area in the RX1 is 132 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.5 and 1.0. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Sensor size

Even though the RX1 has a larger sensor, both cameras offer the same resolution of 24 megapixel. This implies that the RX1 has a lower pixel density and larger individual pixels (with a pixel pitch of 5.96μm 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 much more recent (by 4 years and 4 months) than the RX1, and its sensor will 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 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, but the X-T20 provides a higher video resolution than the RX1. It can shoot video footage at 4K/30p, while the Sony is limited to 1080/60p.

Feature comparison

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 RX1 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-T20, the Sony RX1, and comparable cameras. If needed, the dpreview camera hub, for example, contains further detail on the cameras' specs.

The X-T20 is a current model that online retailers, such as amazon, will have in stock. In contrast, the RX1 has been discontinued (but it can be found pre-owned on ebay). As a replacement in the same line of cameras, the RX1 was succeeded by the Sony RX1R.

Summary

So what is the bottom line? Is the Fujifilm X-T20 better than the Sony RX1 or vice versa? A synthesis of the relative strong points of each of the models is listed below.


logo checkmark

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.
  • 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.
  • Faster burst: Shoots at higher frequency (8 vs 5 flaps/sec) to capture the decisive moment.
  • More flexible: Accepts interchangeable lenses, so that lens characteristics can be altered.
  • Longer lasting: Can take more shots (350 versus 270) on a single battery charge.
  • More modern: Reflects 4 years and 4 months of technical progress since the RX1 launch.

Advantages of the Sony Cyber-shot DSC-RX1:

  • Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
  • More detailed LCD: Has a higher resolution rear screen (1229k vs 1040k dots).
  • Ready to shoot: Has an integrated lens, whereas the X-T20 necessitates an extra lens.
  • More compact: Is smaller (113x65mm vs 118x83mm) and will fit more readily into a bag.
  • More heavily discounted: Has been around for much longer (launched in September 2012).

If the count of individual advantages (bullet points above) is taken as a guide, the X-T20 is the clear winner of the match-up (9 : 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-T20 09:05 RX1

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-T20 or the RX1 handle or perform in practice. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased. 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. You can find the full text of the reviews, respectively, at 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 were established in reference to similarly priced cameras that were available in the market at the time of the review. Hence, a score should always be seen in the context of the camera's market launch date and its price, and comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
