Going beyond this snapshot of core features and characteristics, what are the differences between the Canon PowerShot G15 and the Fujifilm X-A3? Which one should you buy? Read on to find out how these two cameras compare with respect to their body size, their imaging sensors, their shooting features, their input-output connections, and their reception by expert reviewers.

Body comparison

An illustration of the physical size and weight of the Canon G15 and the Fujifilm X-A3 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 size dimensions are rounded to the nearest millimeter.

The X-A3 can be obtained in three different colors (silver, brown, pink), while the G15 is only available in black.

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Fujifilm X-A3 is somewhat smaller (4 percent) than the Canon G15. In this context, it is worth noting that neither the G15 nor the X-A3 are weather-sealed.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the G15 has a lens built 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 compare the optics available for the X-A3 and their specifications in the Fujinon X Lens Catalog.

Concerning battery life, the G15 gets 350 shots out of its Canon NB-10L battery, while the X-A3 can take 410 images on a single charge of its Fujifilm NP-W126S power pack. The power pack in the X-A3 can be charged via the USB port, which can be very convenient when travelling.

The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones.

Any camera decision will naturally be influenced heavily by the price. The manufacturer’s suggested retail prices give an idea on the placement of the camera in the maker’s lineup and the broader market. 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. 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. 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 Canon G15 features a 1/1.7-inch sensor and the Fujifilm X-A3 an APS-C sensor. The sensor area in the X-A3 is 758 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 4.6 and 1.5. The sensor in the G15 has a native 4:3 aspect ratio, while the one in the X-A3 offers a 3:2 aspect.

With 24MP, the X-A3 offers a higher resolution than the G15 (12MP), but the X-A3 nevertheless has larger individual pixels (pixel pitch of 3.92μm versus 1.89μm for the G15) due to its larger sensor. Moreover, the X-A3 is a much more recent model (by 3 years and 11 months) than the G15, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixel-units.

The resolution advantage of the Fujifilm X-A3 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the X-A3 for good quality output (200 dots per inch) amounts to 30 x 20 inches or 76.2 x 50.8 cm, for very good quality (250 dpi) 24 x 16 inches or 61 x 40.6 cm, and for excellent quality (300 dpi) 20 x 13.3 inches or 50.8 x 33.9 cm. The corresponding values for the Canon G15 are 20 x 15 inches or 50.8 x 38.1 cm for good quality, 16 x 12 inches or 40.6 x 30.5 cm for very good quality, and 13.3 x 10 inches or 33.9 x 25.4 cm for excellent quality prints.

The Canon PowerShot G15 has a native sensitivity range from ISO 80 to ISO 12800. The corresponding ISO settings for the Fujifilm X-A3 are ISO 200 to ISO 6400, with the possibility to increase the ISO range to 100-25600.

Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors. Both cameras use a Bayer filter for capturing RGB colors on a square grid of photosensors. This arrangement is found in most digital cameras.

For many 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"). The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

Many modern cameras are not only capable of taking still images, but can also record movies. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the X-A3 provides a faster frame rate than the G15. It can shoot movie footage at 1080/60p, while the Canon is limited to 1080/24p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. For example, the G15 has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the X-A3 relies on live view and the rear LCD for framing. The adjacent table lists some of the other core features of the Canon G15 and Fujifilm X-A3 along with similar information for a selection of comparators.

Note: *) Information refers to the mechanical shutter, unless the camera only has an electronic one.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The X-A3 has a touchscreen, while the G15 has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.

The reported shutter speed information refers to the use of the mechanical shutter. Yet, some cameras only have an electronic shutter, while others have an electronic shutter in addition to a mechanical one. In fact, the X-A3 is one of those camera that have an additional electronic shutter, which makes completely silent shooting possible. However, this mode is less suitable for photographing moving objects (risk of rolling shutter) or shooting under artificial light sources (risk of flickering).

The Fujifilm X-A3 has an intervalometer built-in. This enables the photographer to capture time lapse sequences, such as flower blooming, a sunset or moon rise, without purchasing an external camera trigger and related software.

Concerning the storage of imaging data, both the G15 and the X-A3 write their files to SDXC cards. The X-A3 supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the G15 cannot take advantage of Ultra High Speed SD cards.

Connectivity comparison

For some imaging applications, the extent to which a camera can communicate with its environment can be an important aspect in the camera decision process. The table below provides an overview of the connectivity of the Canon PowerShot G15 and Fujifilm X-A3 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the X-A3 offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the G15 does not provide wifi capability.

Both the G15 and the X-A3 have been discontinued, but can regularly be found used on ebay. The G15 was replaced by the Canon G16, while the X-A3 was followed by the Fujifilm X-A5. Further information on the features and operation of the G15 and X-A3 can be found, respectively, in the Canon G15 Manual (free pdf) or the online Fujifilm X-A3 Manual.

Review summary

So what is the bottom line? Is the Canon G15 better than the Fujifilm X-A3 or vice versa? Below is a summary of the relative strengths of each of the two contestants.

Arguments in favor of the Canon PowerShot G15:

• Easier framing: Has an optical viewfinder for image composition and settings control.
• Ready to shoot: Has a lens built-in, whereas the X-A3 requires a separate lens.
• Sharper images: Has hand-shake reducing image stabilization built-in.
• More heavily discounted: Has been available for much longer (launched in September 2012).

Advantages of the Fujifilm X-A3:

• More detail: Has more megapixels (24 vs 12MP), which boosts linear resolution by 44%.
• Better image quality: Is equipped with a larger and more technologically advanced sensor.
• Richer colors: The sensor size advantage translates into images with better, more accurate colors.
• More dynamic range: Larger sensor captures a wider spectrum of light and dark details.
• Better low-light sensitivity: Larger sensor produces good images even in poorly lit environments.
• Better video: Provides higher movie framerates (1080/60p versus 1080/24p).
• More detailed LCD: Has a higher resolution rear screen (1040k vs 922k dots).
• More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
• Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
• More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
• Faster burst: Shoots at higher frequency (6 vs 2.1 flaps/sec) to capture the decisive moment.
• Less disturbing: Has an electronic shutter option for completely silent shooting.
• Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
• More flexible: Takes interchangeable lenses and can thus be used with specialty optics.
• Longer lasting: Gets more shots (410 versus 350) out of a single battery charge.
• Easier travel charging: Can be conveniently charged via its USB port.
• Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
• Faster buffer clearing: Has an SD card interface that supports the UHS-I standard.
• More modern: Reflects 3 years and 11 months of technical progress since the G15 launch.

If the number of relative strengths (bullet points above) is taken as a guide, the X-A3 is the clear winner of the contest (19 : 4 points). 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. A professional wildlife photographer will view the differences between cameras in a way that diverges from the perspective of a family photog, and a person interested in architecture has distinct needs from a sports shooter. Hence, the decision which camera is best and worth buying is often a very personal one.

How about other alternatives? Do the specifications of the Canon G15 and the Fujifilm X-A3 place the cameras among the top in their class? Find out in the latest Best Travel-Zoom Camera and Best Mirrorless Interchangeable Lens Camera listings whether the two cameras rank among the cream of the crop.

In any case, while the specs-based evaluation of cameras can be instructive in revealing their potential as photographic tools, it remains incomplete and does no justice, for example, to the way the G15 or the X-A3 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.

Expert reviews

This is why hands-on reviews by experts are important. The table below provides a synthesis of the camera assessments of some of the best known photo-gear review sites (amateurphotographer [AP], cameralabs [CL], digitalcameraworld [DCW], dpreview [DPR], ephotozine [EPZ], photographyblog [PB]). As can be seen, the professional reviewers agree in many cases on the quality of different cameras, but sometimes their assessments diverge, reinforcing the earlier point that a camera decision is often a very personal choice.

The review scores listed above should be treated 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 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.
