Sony A9 versus Fujifilm X-T2

The Sony Alpha A9 and the Fujifilm X-T2 are two digital cameras that were revealed to the public, respectively, in April 2017 and July 2016. Both the A9 and the X-T2 are mirrorless interchangeable lens cameras that are based on a full frame (A9) and an APS-C (X-T2) 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: Sony A9 vs Fujifilm X-T2

An illustration of the physical size and weight of the Sony A9 and the Fujifilm X-T2 is provided in the side-by-side display below. The two cameras are presented according to their relative size. Three consecutive perspectives from the front, the top, and the back are available. All width, height and depth dimensions 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 A9 – 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 A9 and the Fujifilm X-T2 are of equal size. However, the X-T2 is markedly lighter (25 percent) than the A9. In this context, it is worth noting that both cameras are splash and dust-proof and can, hence, be used in inclement weather conditions or harsh environments.

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 (A9) and the Fujinon X Lens Catalog (X-T2). 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 A9 gets 650 shots out of its NP-FZ100 battery, while the X-T2 can take 340 images on a single charge of its NP-W126S power pack.

The price is, of course, an important factor in any camera decision. The retail prices at the time of the camera’s release place the model in the market relative to other models in the producer’s line-up and the competition. The X-T2 was launched at a markedly lower price (by 64 percent) than the A9, 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: Sony A9 vs Fujifilm X-T2

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.

Of the two cameras under consideration, the Sony A9 features a full frame sensor and the Fujifilm X-T2 an APS-C sensor. The sensor area in the X-T2 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 A9 and Fujifilm X-T2 sensor measures

Even though the A9 has a larger sensor, both cameras offer the same resolution of 24 megapixel. This implies that the A9 has a lower pixel density and larger individual pixels (with a pixel pitch of 5.94μm versus 3.92μm for the X-T2), which gives it a potential advantage in terms of light gathering capacity. In addition, the A9 is a somewhat more recent model (by 9 months) than the X-T2, and its sensor might have benefitted from technological advances during this time. Coming back to sensor resolution, it should be mentioned that the X-T2 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

One feature that differentiates the A9 and the X-T2 is in-body image stabilization (IBIS). The A9 reduces the risk of handshake-induced blur with all attached lenses, while the X-T2 has to rely on optical image stabilization in OIS-equipped lenses to achieve the same effect.

The reported shutter speed and shutter burst refer to the use of the mechanical shutter. In addition, the A9 features an electronic shutter, which makes completely silent shooting possible. However, this mode is less suitable for photographing moving objects (rolling shutter) or shooting under artificial light sources (flickering).

The A9 writes its imaging data to SDXC or Memory Stick PRO Duo cards, while the X-T2 uses SDXC cards. Both cameras feature dual card slots, which can be very useful in case a memory card fails.

The A9 is a current model that online retailers, such as amazon, will have in stock. In contrast, the X-T2 has been discontinued (but it can be found pre-owned on eBay). As a replacement in the same line of cameras, the X-T2 was succeeded by the Fujifilm X-T3 .

Review summary: Sony A9 vs Fujifilm X-T2

So how do things add up? Is the Sony A9 better than the Fujifilm X-T2 or vice versa? The listing below highlights the relative strengths of the two models.

ilogo

Reasons to prefer the Sony Alpha A9:

  • Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
  • Better image quality: Features a larger and more technologically advanced imaging sensor.
  • Better sound control: Has a headphone port that enables audio monitoring while recording.
  • More detailed viewfinder: Has higher resolution electronic viewfinder (3686k vs 2360k dots).
  • More detailed LCD: Has a higher resolution rear screen (1440k vs 1040k dots).
  • Fewer buttons to press: Is equipped with a touch-sensitive rear screen to facilitate handling.
  • Faster burst: Shoots at higher frequency (20 vs 14 flaps/sec) to capture the decisive moment.
  • Less disturbing: Has an electronic shutter option for completely silent shooting.
  • Longer lasting: Can take more shots (650 versus 340) on a single battery charge.
  • Sharper images: Has hand-shake reducing image stabilization build-in.
  • Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
  • Easier wireless transfer: Supports Bluetooth for image sharing without cables.
  • More modern: Is somewhat more recent (announced 9 months after the X-T2).

ilogo

Arguments in favor of the Fujifilm X-T2:

  • Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
  • Less heavy: Has a lower weight (by 166g or 25 percent) and is thus easier to take along.
  • Faster data transfer: Supports a more advanced USB protocol (3.0 vs 2.0).
  • More affordable: Was introduced into a lower priced category (64 percent cheaper at launch).
  • More heavily discounted: Has been on the market for longer (launched in July 2016).

If the count of relative strengths (bullet points above) is taken as a measure, the A9 is the clear winner of the match-up (13 : 5 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.

A9 13:05 X-T2

In any case, while the specs-based evaluation of cameras is instructive in revealing their potential as photographic tools, it remains incomplete and does no justice, for example, to the way the A9 or the X-T2 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 why hands-on reviews by experts are important. The table below summarizes the assessments of some of the best known camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, photographyblog).

Care should be taken when interpreting the review scores above, though. The ratings are only valid when referring 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 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.
