Sony A7 III vs Canon SL3

The Sony Alpha A7 III and the Canon EOS Rebel SL3 (labelled Canon 250D in some countries) are two digital cameras that were announced, respectively, in February 2018 and April 2019. The A7 III is a mirrorless interchangeable lens camera, while the SL3 is a DSLR. The cameras are based on a full frame (A7 III) and an APS-C (SL3) sensor. Both cameras offer a resolution of 24 megapixels.

Below is an overview of the main specs of the two cameras as a starting point for the comparison.

Body comparison

An illustration of the physical size and weight of the Sony A7 III and the Canon SL3 is provided in the side-by-side display below. 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.

The SL3 can be obtained in two different colors (black, white), while the A7 III is only available in black.

Size Sony A7 III vs Canon SL3
Compare A7 III versus SL3 top
Comparison A7 III or SL3 rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Canon SL3 is notably smaller (7 percent) than the Sony A7 III. Moreover, the SL3 is markedly lighter (31 percent) than the A7 III. It is worth mentioning in this context that the A7 III is splash and dust resistant, while the SL3 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 compare the optics available for the two cameras in the Sony FE Lens Catalog (A7 III) and the Canon EF Lens Catalog (SL3). Mirrorless cameras, such as the Sony A7 III, have moreover the advantage that they have a relatively short flange to focal plane distance and can thus use many lenses from other systems via adapters.

Concerning battery life, the A7 III gets 610 shots out of its Sony NP-FZ100 battery, while the SL3 can take 1070 images on a single charge of its Canon LP-E17 power pack. The power pack in the A7 III can be charged via the USB port, so that it is not always necessary to take the battery charger along when travelling.

The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives. In case you want to display and compare another camera duo, you can use the CAM-parator app to select your camera combination among a large number of options.

Any camera decision will naturally be influenced heavily by the price. 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 SL3 was launched at a markedly lower price (by 70 percent) than the A7 III, 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.

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. 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 A7 III features a full frame sensor and the Canon SL3 an APS-C sensor. The sensor area in the SL3 is 61 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.0 and 1.6. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Sony A7 III and Canon SL3 sensor measures

Even though the A7 III has a larger sensor, both cameras offer the same resolution of 24 megapixels. This implies that the A7 III has a lower pixel density and larger individual pixels (with a pixel pitch of 5.94μm versus 3.72μm for the SL3), which gives it a potential advantage in terms of light gathering capacity. It should, however, be noted that the SL3 is a somewhat more recent model (by 1 year and 1 month) than the A7 III, and its sensor might have benefitted from technological advances during this time that at least partly compensate for the smaller pixel size.

The Sony Alpha A7 III has a native sensitivity range from ISO 100 to ISO 51200, which can be extended to ISO 50-204800. The corresponding ISO settings for the Canon EOS Rebel SL3 are ISO 100 to ISO 25600, with the possibility to increase the ISO range to 100-51200.

In terms of underlying technology, the A7 III is build around a BSI-CMOS sensor, while the SL3 uses a CMOS imager. Both cameras use a Bayer filter for capturing RGB colors on a square grid of photosensors. This arrangement is found in most digital cameras.

A7 III versus SL3 MP

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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 following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.

Many modern cameras are not only capable of taking still images, but also of capturing video footage. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, but the A7 III provides a higher frame rate than the SL3. It can shoot video footage at 4K/30p, while the Canon is limited to 4K/25p.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. For example, the A7 III has an electronic viewfinder (2359k dots), while the SL3 has an optical one. Both systems have their advantages, with the electronic viewfinder making it possible to project supplementary shooting information into the framing view, whereas the optical viewfinder offers lag-free viewing and a very clear framing image. The viewfinder in the A7 III offers a wider field of view (100%) than the one in the SL3 (95%), so that a larger proportion of the captured image is visible in the finder. In addition, the viewfinder of the A7 III has a higher magnification (0.78x vs 0.54x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The adjacent table lists some of the other core features of the Sony A7 III and Canon SL3 along with similar information for a selection of comparators.

One feature that differentiates the A7 III and the SL3 is in-body image stabilization (IBIS). The A7 III reduces the risk of handshake-induced blur with all attached lenses, while the SL3 offers no blur reduction with lenses that themselves do not provide optical image stabilization.

The SL3 has an articulated screen that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in taking selfies. In contrast, the A7 III does not have a selfie-screen.

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 A7 III 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 Sony A7 III and the Canon SL3 both have 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.

The A7 III writes its imaging data to SDXC or Memory Stick PRO Duo cards, while the SL3 uses SDXC cards. The A7 III features dual card slots, which can be very useful in case a memory card fails. In contrast, the SL3 only has one slot. The A7 III supports UHS-II cards (on its first slot), while the SL3 can use UHS-I cards.

  • More flexible LCD: Has a swivel screen for odd-angle shots in portrait or landscape orientation.
  • More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
  • Less heavy: Has a lower weight (by 201g or 31 percent) and is thus easier to take along.
  • Longer lasting: Gets more shots (1070 versus 610) out of a single battery charge.
  • Easier fill-in: Has a small integrated flash to brighten shadows of backlit subjects.
  • More affordable: Was introduced into a lower priced category (70 percent cheaper at launch).
  • More modern: Was introduced somewhat (1 year and 1 month) more recently.

If the count of relative strengths (bullet points above) is taken as a measure, the A7 III is the clear winner of the match-up (21 : 9 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 wedding photographer will view the differences between cameras in a way that diverges from the perspective of a travel photog, and a person interested in cityscapes has distinct needs from a macro shooter. Hence, the decision which camera is best and worth buying is often a very personal one.

A7 III 21:09 SL3

How about other alternatives? Do the specifications of the Sony A7 III and the Canon SL3 place the cameras among the top in their class? Find out in the latest Best Mirrorless Interchangeable Lens Camera and Best DSLR Camera listings whether the two cameras rank among the cream of the crop.

In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it remains incomplete and does no justice, for example, to the way the A7 III or the SL3 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 where reviews by experts come in. 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 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. Hence, a score should always be seen in the context of the camera's market launch date and its price, and comparisons of ratings among very different cameras or across long time periods have little meaning. Also, please note that some of the review sites have changed their methodology and reporting over time.
