Canon T7i vs Leica SL3

The Canon EOS Rebel T7i (called Canon 800D in some regions) and the Leica SL3 are two digital cameras that were announced, respectively, in February 2017 and March 2024. The T7i is a DSLR, while the Leica SL3 is a mirrorless interchangeable lens camera. The cameras are based on an APS-C (T7i) and a full frame (Leica SL3) sensor. The Canon has a resolution of 24 megapixels, whereas the Leica provides 60.3 MP.

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 Canon T7i and the Leica SL3 is provided in the side-by-side display below. The two cameras are presented according to their relative size. Three consecutive views from the front, the top, and the rear side are shown. All width, height and depth measures are rounded to the nearest millimeter.

Size Canon T7i vs Leica SL3
Compare T7i versus Leica SL3 top
Comparison T7i or Leica SL3 rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Leica SL3 is notably larger (16 percent) than the Canon T7i. Moreover, the Leica SL3 is substantially heavier (45 percent) than the T7i. It is noteworthy in this context that the Leica SL3 is splash and dust-proof, while the T7i 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. Hence, you might want to study and compare the specifications of available lenses in order to get the full picture of the size and weight of the two camera systems.

Concerning battery life, the T7i gets 600 shots out of its Canon LP-E17 battery, while the Leica SL3 can take 320 images on a single charge of its Leica BP-SCL6 power pack. The power pack in the Leica SL3 can be charged via the USB port, which can be very convenient when travelling.

The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives.

Any camera decision will obviously take relative prices into account. 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 T7i was launched at a markedly lower price (by 89 percent) than the Leica SL3, 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 imaging sensor is at the core of digital cameras and its size is one of the main determining factors 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 tend to be more expensive and lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Canon T7i features an APS-C sensor and the Leica SL3 a full frame sensor. The sensor area in the Leica SL3 is 160 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.6 and 1.0. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Canon T7i and Leica SL3 sensor measures

With 60.3MP, the Leica SL3 offers a higher resolution than the T7i (24MP), but the Leica SL3 nevertheless has marginally larger individual pixels (pixel pitch of 3.79μm versus 3.72μm for the T7i) due to its larger sensor. Moreover, the Leica SL3 is a much more recent model (by 7 years) than the T7i, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixel-units. Coming back to sensor resolution, it should be mentioned that the Leica SL3 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The resolution advantage of the Leica SL3 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the Leica SL3 for good quality output (200 dots per inch) amounts to 47.6 x 31.7 inches or 120.9 x 80.5 cm, for very good quality (250 dpi) 38.1 x 25.3 inches or 96.7 x 64.4 cm, and for excellent quality (300 dpi) 31.7 x 21.1 inches or 80.6 x 53.6 cm. The corresponding values for the Canon T7i are 30 x 20 inches or 76.2 x 50.8 cm for good quality, 24 x 16 inches or 61 x 40.6 cm for very good quality, and 20 x 13.3 inches or 50.8 x 33.9 cm for excellent quality prints.

The Canon EOS Rebel T7i has a native sensitivity range from ISO 100 to ISO 25600, which can be extended to ISO 100-51200. The corresponding ISO settings for the Leica SL3 are ISO 100 to ISO 100000, with the possibility to increase the ISO range to 50-100000.

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.

Many modern cameras are not only capable of taking still images, but can also record movies. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, but the Leica SL3 provides a better video resolution than the T7i. It can shoot movie footage at 8K/30p, while the Canon is limited to 1080/60p.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. For example, the Leica SL3 has an electronic viewfinder (5760k dots), while the T7i 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 Leica SL3 offers a wider field of view (100%) than the one in the T7i (95%), so that a larger proportion of the captured image is visible in the finder. In addition, the viewfinder of the Leica SL3 has a higher magnification (0.76x vs 0.51x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The following table reports on some other key feature differences and similarities of the Canon T7i, the Leica SL3, and comparable cameras.

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

One difference between the cameras concerns the presence of an on-board flash. The T7i has one, while the Leica SL3 does not. While the built-in flash of the T7i is not very powerful, it can at times be useful as a fill-in light.

The T7i has an articulated LCD that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in snapping selfies. In contrast, the Leica SL3 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 Leica SL3 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 Leica SL3 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.

The T7i writes its imaging data to SDXC cards, while the Leica SL3 uses CFexpress (type B) or SDXC cards. The Leica SL3 features dual card slots, which can be very useful in case a memory card fails. In contrast, the T7i only has one slot. The Leica SL3 supports UHS-II cards (Ultra High Speed data transfer of up to 312 MB/s), while the T7i can use UHS-I cards (up to 104 MB/s).

It is notable that the Leica SL3 has a headphone jack, which makes it possible to attach external headphones and monitor the quality of sound during the recording process. The T7i lacks such a headphone port.

The Leica SL3 is a recent model that features in the current product line-up of Leica. In contrast, the T7i has been discontinued (but can be found pre-owned on ebay). As a replacement in the same line of cameras, the T7i was succeeded by the Canon T8i. Further information on the features and operation of the T7i and Leica SL3 can be found, respectively, in the Canon T7i Manual (free pdf) or the online Leica SL3 Manual.

If the count of individual advantages (bullet points above) is taken as a guide, the Leica SL3 is the clear winner of the contest (27 : 12 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. 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.

T7i 12:27 Leica SL3

How about other alternatives? Do the specifications of the Canon T7i and the Leica SL3 place the cameras among the top in their class? Find out in the latest Best DSLR 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 partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the T7i or the Leica SL3. User reviews that are available, for instance, at amazon can sometimes shed light on these issues, but such feedback is all too often partial, inconsistent, and inaccurate.

Expert reviews

This is where reviews by experts come in. The adjacent summary-table relays the overall verdicts of several of the most popular camera 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.

Note: (+ +) highly recommended; (+) recommended; (o) reviewed; (..) not available.

The review scores listed above should be treated with care, though. The assessments were made in relation to similar cameras of the same technological generation. Hence, a score should always be seen in the context of the camera's market launch date and its price, 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.
