Fujifilm X-A3 versus Canon G7 X Mark II

The Fujifilm X-A3 and the Canon PowerShot G7 X Mark II are two digital cameras that were officially introduced, respectively, in August 2016 and February 2016. The X-A3 is a mirrorless interchangeable lens camera, while the G7X Mark II is a fixed lens compact. The cameras are based on an APS-C (X-A3) and an one-inch sensor. The Fujifilm has a resolution of 24 megapixel, whereas the Canon provides 20 MP.

Body comparison

An illustration of the physical size and weight of the Fujifilm X-A3 and the Canon G7 X Mark II is provided in the side-by-side display below. Three consecutive perspectives from the front, the top, and the back are presented. 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-A3 – 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 Canon G7 X Mark II is notably smaller (18 percent) than the Fujifilm X-A3. In this context, it is worth noting that neither the X-A3 nor the G7X Mark II are weather-sealed.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the G7X Mark II has a lens build in, whereas the X-A3 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-A3 and their specifications in the Fujinon X Lens Catalog.

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 imaging sensor is a crucial determinant 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. 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 associated with larger, more expensive camera bodies and lenses.

Of the two cameras under consideration, the Fujifilm X-A3 features an APS-C sensor and the Canon G7 X Mark II an one-inch sensor. The sensor area in the G7X Mark II is 69 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.5 and 2.7. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Sensor size

With 24MP, the X-A3 offers a higher resolution than the G7X Mark II (20MP), but the X-A3 nevertheless has larger individual pixels (pixel pitch of 3.92μm versus 2.41μm for the G7X Mark II) due to its larger sensor. Moreover, the X-A3 is a somewhat more recent model (by 6 months) than the G7X Mark II, and its sensor might have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixels.

For most cameras, data on sensor performance has been reported by DXO Mark. 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").

Many modern cameras cannot only take still pictures, but also record videos. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, and both provide the same movie specifications (1080/60p).

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. The X-A3 and the G7X Mark II are similar in the sense that neither of the two has a viewfinder. The images are, thus, framed using live view on the rear LCD. The table below summarizes some of the other core capabilities of the Fujifilm X-A3 and Canon G7 X Mark II in connection with corresponding information for a sample of similar cameras. The full specs-sheets can be found in the camera manual or, for example, in the dpreview camera hub.

Both the X-A3 and the G7X Mark II are current models that good online retailers will have in stock. You can check the latest prices, for example, at amazon. The G7X Mark II replaced the earlier Canon G7 X, while the X-A3 followed on from the Fujifilm X-A2.

Summary

So what conclusions can be drawn? Is the Fujifilm X-A3 better than the Canon G7 X Mark II or vice versa? A synthesis of the relative strong points of each of the models is listed below.


logo checkmark

Advantages of the Fujifilm X-A3:

  • More detail: Offers more megapixels (24 vs 20MP) with a 10% higher linear resolution.
  • Better image quality: Features a larger and more technologically advanced imaging sensor.
  • Faster shutter: Has a higher mechanical shutter speed (4000/sec vs 2000/sec) to freeze action.
  • More flexible: Accepts interchangeable lenses, so that lens characteristics can be altered.
  • Longer lasting: Can take more shots (410 versus 265) on a single battery charge.
  • More modern: Is somewhat more recent (announced 6 months after the G7X Mark II).

logo checkmark

Arguments in favor of the Canon PowerShot G7 X Mark II:

  • Faster burst: Shoots at higher frequency (8 vs 6 flaps/sec) to capture the decisive moment.
  • Ready to shoot: Has an integrated lens, whereas the X-A3 necessitates an extra lens.
  • More compact: Is smaller (106x61mm vs 117x67mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight even though it has a lens build in (unlike the X-A3).
  • 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 G7X Mark II (6 : 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.

In any case, while the specs-based evaluation of cameras is instructive in revealing their potential as photographic tools, it remains partial and cannot reveal, for example, the handling experience and imaging performance when actually working with the X-A3 or the G7X Mark II. 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. The full reviews are available, 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 ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, and comparisons of ratings among very different cameras or across long time periods have little meaning. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
