Sony A7R versus Fujifilm X-E3

The Sony Alpha A7R and the Fujifilm X-E3 are two digital cameras that were revealed to the public, respectively, in October 2013 and September 2017. Both the A7R and the X-E3 are mirrorless interchangeable lens cameras that are based on a full frame (A7R) and an APS-C (X-E3) sensor. The Sony has a resolution of 36.2 megapixel, whereas the Fujifilm provides 24 MP. 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: Sony A7R vs Fujifilm X-E3

The side-by-side display below illustrates the physical size and weight of the Sony A7R and the Fujifilm X-E3. 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 A7R – represents 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-E3 is notably smaller (25 percent) than the Sony A7R. Moreover, the X-E3 is markedly lighter (28 percent) than the A7R. It is worth mentioning in this context that the A7R is splash and dust resistant, while the X-E3 does not feature any corresponding weather-sealing.

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. A larger imaging sensor will tend to go along with bigger and heavier lenses, although exceptions exist. You can find an overview of optics for the two cameras in the Sony FE Lens Catalog (A7R) and the Fujinon X Lens Catalog (X-E3). 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.

Concerning battery life, the A7R gets 340 shots out of its NP-FW50 battery, while the X-E3 can take 350 images on a single charge of its NP-W126S power pack.

The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives. 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-E3 was launched at a markedly lower price (by 61 percent) than the A7R, 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: Sony A7R vs Fujifilm X-E3

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.

Of the two cameras under consideration, the Sony A7R features a full frame sensor and the Fujifilm X-E3 an APS-C sensor. The sensor area in the X-E3 is 57 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.0 and 1.5. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Sony A7R and Fujifilm X-E3 sensor measures

With 36.2MP, the A7R offers a higher resolution than the X-E3 (24MP), but the A7R nevertheless has larger individual pixels (pixel pitch of 4.88μm versus 3.92μm for the X-E3) due to its larger sensor. However, the X-E3 is a somewhat more recent model (by 3 years and 10 months) than the A7R, and its sensor might have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixels. Coming back to sensor resolution, it should be mentioned that neither of the two cameras has an anti-alias filter installed, so they are able to capture all the detail the 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-E3 provides a better video resolution than the A7R. It can shoot movie footage at 4K/30p, while the Sony is limited to 1080/60p.

 

Feature comparison: Sony A7R vs Fujifilm X-E3

Apart from body and sensor, cameras can and do differ across a range of features. The two cameras under consideration are similar with respect to both having an electronic viewfinder. However, the one in the A7R offers a slightly higher resolution than the one in the X-E3 (2400k vs 2360k dots).

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The X-E3 has a touchscreen, while the A7R has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point or for making menu selections.

The X-E3 is a current model that online retailers, such as amazon, will have in stock. In contrast, the A7R has been discontinued (but it can be found pre-owned on eBay). As a replacement in the same line of cameras, the A7R was succeeded by the Sony A7R II.

Review summary: Sony A7R vs Fujifilm X-E3

So what is the bottom line? Is there a clear favorite between the Sony A7R and the Fujifilm X-E3? The listing below highlights the relative strengths of the two models.

Arguments in favor of the Sony Alpha A7R:

  • More detail: Offers more megapixels (36.2 vs 24MP) with a 23% higher linear resolution.
  • More detailed LCD: Has a higher resolution rear screen (1230k vs 1040k dots).
  • More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
  • Faster shutter: Has higher mechanical shutter speed (8000/sec vs 4000/sec) to freeze action.
  • Better sealing: Is weather sealed to enable shooting in dusty or wet environments.
  • More heavily discounted: Has been available for much longer (launched in October 2013).

ilogo

Reasons to prefer the Fujifilm X-E3:

  • Better video: Provides higher definition movie capture (4K/30p vs 1080/60p).
  • Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
  • Faster burst: Shoots at higher frequency (8 vs 4 flaps/sec) to capture the decisive moment.
  • More compact: Is smaller (121x74mm vs 127x94mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight (by 128g or 28 percent) and is thus easier to take along.
  • More affordable: Was introduced into a lower priced category (61 percent cheaper at launch).
  • More modern: Reflects 3 years and 10 months of technical progress since the A7R launch.

If the count of individual advantages (bullet points above) is taken as a guide, the X-E3 comes out slightly ahead of the A7R (7 : 6 points). However, the relevance of individual strengths will vary across photographers, so that you might want to apply your own weighing scheme to the summary points when reflecting and deciding on a new camera.

A7R 06:07 X-E3

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 A7R or the X-E3 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 where reviews by experts come in.

The review scores listed above should be treated with care, 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 rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, please note that some of the review sites have changed their methodology and reporting over time.
