Fujifilm X70 versus Sony A7

The Fujifilm X70 and the Sony Alpha A7 are two digital cameras that were revealed to the public, respectively, in January 2016 and October 2013. The X70 is a fixed lens compact, while the A7 is a mirrorless interchangeable lens camera. The cameras are based on an APS-C (X70) and a full frame (A7) sensor. The Fujifilm has a resolution of 16 megapixel, whereas the Sony 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: Fujifilm X70 vs Sony A7

An illustration of the physical size and weight of the Fujifilm X70 and the Sony A7 is provided in the side-by-side display below. Three consecutive perspectives from the front, the top, and the back are presented. All size 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 X70 – 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 A7 is considerably larger (65 percent) than the Fujifilm X70. It is noteworthy in this context that the A7 is splash and dust-proof, while the X70 does not feature any corresponding weather-sealing.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the X70 has a lens build in, whereas the A7 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 A7 and their specifications in the Sony FE Lens Catalog.

Concerning battery life, the X70 gets 330 shots out of its NP-95 battery, while the A7 can take 340 images on a single charge of its NP-FW50 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 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 X70 was launched at a lower price than the A7, despite having a lens build in. 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 X70 vs Sony A7

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. Furthermore, a large sensor camera will give the photographer more possibilities to use shallow depth-of-field in order to 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.

Of the two cameras under consideration, the Fujifilm X70 features an APS-C sensor and the Sony A7 a full frame sensor. The sensor area in the A7 is 133 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

With 24MP, the A7 offers a higher resolution than the X70 (16MP), but the A7 nevertheless has larger individual pixels (pixel pitch of 5.97μm versus 4.80μm for the X70) due to its larger sensor. However, the X70 is a much more recent model (by 2 years and 2 months) than the A7, and its sensor will have benefitted from technological advances during this time that enhance the light gathering capacity of its pixel-units. Coming back to sensor resolution, it should be mentioned that the X70 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 have a sensor with sufficiently fast read-out times for moving pictures, and both provide the same movie specifications (1080/60p).

Feature comparison: Fujifilm X70 vs Sony A7

Apart from body and sensor, cameras can and do differ across a range of features. For example, the A7 has an electronic viewfinder (2400k dots), which can be very helpful when shooting in bright sunlight. In contrast, the X70 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 X70, the Sony A7, and comparable cameras. If you need more detail on the specs, you can find comprehensive listings, for example, in the dpreview camera hub.

The X70 is a current model that online retailers, such as amazon, will have in stock. In contrast, the A7 has been discontinued (but it can be found pre-owned on eBay). As a replacement in the same line of cameras, the A7 was succeeded by the Sony A7 II.

Review summary: Fujifilm X70 vs Sony A7

So how do things add up? Which of the two cameras – the Fujifilm X70 or the Sony A7 – has the upper hand? Below is a summary of the relative strengths of each of the two contestants.


logo checkmark

Arguments in favor of the Fujifilm X70:

  • Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
  • 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.
  • Ready to shoot: Has a lens build-in, whereas the A7 requires a separate lens.
  • More compact: Is smaller (113x64mm vs 127x94mm) and thus needs less room in the bag.
  • Less heavy: Is lighter even though it comes with a build-in lens (unlike the A7).
  • Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
  • More affordable: Was introduced at a lower price, despite coming with a build-in lens.
  • More modern: Reflects 2 years and 2 months of technical progress since the A7 launch.

Advantages of the Sony Alpha A7:

  • More detail: Has more megapixels (24 vs 16MP), which boosts linear resolution by 23%.
  • Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
  • Better low-light imaging: Features bigger pixels on a larger sensor for better high-ISO images.
  • Easier framing: Has an electronic viewfinder for image framing and settings control.
  • More detailed LCD: Has a higher resolution rear screen (1230k vs 1040k dots).
  • Faster shutter: Has higher mechanical shutter speed (8000/sec vs 4000/sec) to freeze action.
  • More flexible: Takes interchangeable lenses and can thus be used with specialty optics.
  • Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
  • More heavily discounted: Has been around for much longer (launched in October 2013).

If the number of relative strengths (bullet points above) is taken as a guide, the match-up finishes in a tie (9 points each). 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.

X70 09:09 A7

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 X70 and the A7 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 where reviews by experts come in. The table below summarizes the assessments of some of the best known 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.

The above review scores should be interpreted 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 comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. Also, please note that some of the review sites have changed their methodology and reporting over time.
