Canon SL3 vs T7
The Canon EOS Rebel SL3 (called Canon 250D in some regions) and the Canon EOS Rebel T7 (labelled Canon 2000D in some countries) are two digital cameras that were revealed to the public, respectively, in April 2019 and February 2018. Both are DSLR (Digital Single Lens Reflex) cameras that are equipped with an APS-C sensor. Both cameras offer a resolution of 24 megapixels.
As their names suggest, both the Canon EOS Rebel SL3 and the Canon EOS Rebel T7 belong to Canon's Rebel line of DSLR cameras. This range of APS-C cameras, which started out with the Canon EOS Digital Rebel in 2003, has been a big commercial success and the backbone of Canon's dominance in the digital camera market. The popularity of the Rebel cameras is the result of them inheriting much of the sensor and shooting technology from earlier released professional DSLRs, while being sold at a much more budget-friendly price point. The strong brand reputation of Canon and the comprehensive EOS system of compatible lenses and accessories further contributes to the appeal of the Rebel cams, including the Canon SL3 and Canon T7. Below is an overview of the main specs of the two cameras as a starting point for the comparison.

Going beyond this snapshot of core features and characteristics, what are the differences between the Canon EOS Rebel SL3 and the Canon EOS Rebel T7? 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.
The physical size and weight of the Canon SL3 and the Canon T7 are illustrated 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 dimensions are rounded to the nearest millimeter.
The SL3 can be obtained in two different colors (black, white), while the T7 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 Canon T7 is notably larger (15 percent) than the Canon SL3. Moreover, the T7 is markedly heavier (6 percent) than the SL3. In this context, it is worth noting that neither the SL3 nor the T7 are weather-sealed.
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. In this particular case, both cameras feature the same lens mount, so that they can use the same lenses. You can compare the optics available in the Canon EF Lens Catalog.
The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. 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.

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 T7 was launched at a somewhat lower price (by 25 percent) than the SL3, which makes it more attractive for photographers on a tight budget. Normally, street prices remain initially close to the MSRP, but after a couple of months, the first discounts appear. 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.
The imaging sensor is at the core of digital cameras and its size is one of the main determining factors 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. Furthermore, a large sensor camera will give the photographer more possibilities to use shallow depth-of-field in order to isolate a subject from the background. On the downside, larger sensors tend to be more expensive and lead to bigger and heavier cameras and lenses.
Both cameras under consideration feature an APS-C sensor and have a format factor (sometimes also referred to as "crop factor") of 1.6. Within the spectrum of camera sensors, this places the review cameras among the medium-sized sensor cameras that aim to strike a balance between image quality and portability. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.
In terms of chip-set technology, the SL3 uses a more advanced image processing engine (DIGIC 8) than the T7 (DIGIC 4+), with benefits for noise reduction, color accuracy, and processing speed.
The two cameras under review do not only share the same sensor size, but also offer an identical resolution of 24 megapixels. This similarity in sensor specs implies that both the SL3 and the T7 have the same pixel density, as well as the same pixel size. It should, however, be noted that the SL3 is a somewhat more recent model (by 1 year and 1 month) than the T7, and its sensor might have benefitted from technological advances during this time.
The SL3 has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.
The Canon EOS Rebel SL3 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 Canon EOS Rebel T7 are ISO 100 to ISO 6400, with the possibility to increase the ISO range to 100-12800.
Consistent information on actual sensor performance is available from DXO Mark for many cameras. This service assesses and scores the color depth ("DXO Portrait"), dynamic range ("DXO Landscape"), and low-light sensitivity ("DXO Sports") of camera sensors, and also publishes an overall camera score. The adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-cameras.

Many modern cameras are not only capable of taking still images, but also of capturing video footage. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the SL3 provides a higher video resolution than the T7. It can shoot video footage at 4K/25p, while the T7 is limited to 1080/30p.
Apart from body and sensor, cameras can and do differ across a variety of features. The SL3 and the T7 are similar in the sense that both have an optical viewfinder. The latter is useful for getting a clear image for framing even in brightly lit environments. The viewfinders of both cameras offer the same field of view (95%), but the viewfinder of the SL3 has a higher magnification than the one of the T7 (0.54x vs 0.50x), 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 SL3, the Canon T7, and comparable cameras.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The SL3 has a touchscreen, while the T7 has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.The SL3 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 T7 does not have a selfie-screen.
The Canon 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.
Concerning the storage of imaging data, both the SL3 and the T7 write their files to SDXC cards. The SL3 supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the T7 cannot take advantage of Ultra High Speed SD cards.
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 EOS Rebel SL3 and Canon EOS Rebel T7 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the SL3 has a microphone port, which is missing on the T7. Such an external microphone input can help to substantially improve the quality of audio recordings when a good external microphone is used.
Both the SL3 and the T7 are recent models that are part of the current product line-up. The T7 replaced the earlier Canon T6, while the SL3 followed on from the Canon SL2. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Canon website.
So what conclusions can be drawn? Which of the two cameras – the Canon SL3 or the Canon T7 – has the upper hand? Is one clearly better than the other? The listing below highlights the relative strengths of the two models.
Reasons to prefer the Canon EOS Rebel SL3:
- Better jpgs: Has a more modern image processing engine (DIGIC 8 vs DIGIC 4+).
- Better video: Provides higher definition movie capture (4K/25p vs 1080/30p).
- Better live-view autofocus: Features on-sensor phase-detection for more confident autofocus.
- Better sound: Can connect to an external microphone for higher quality sound recording.
- Larger viewfinder image: Features a viewfinder with a higher magnification (0.54x vs 0.50x).
- More detailed LCD: Has a higher resolution rear screen (1040k vs 920k dots).
- More flexible LCD: Has a swivel screen for odd-angle shots in portrait or landscape orientation.
- Fewer buttons to press: Is equipped with a touch-sensitive rear screen to facilitate handling.
- More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
- Faster burst: Shoots at higher frequency (5 vs 3 flaps/sec) to capture the decisive moment.
- Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
- More compact: Is smaller (122x93mm vs 129x101mm) and thus needs less room in the bag.
- Longer lasting: Can take more shots (1070 versus 500) on a single battery charge.
- Easier wireless transfer: Supports Bluetooth for image sharing without cables.
- Faster buffer clearing: Has an SD card interface that supports the UHS-I standard.
- More modern: Is somewhat more recent (announced 1 year and 1 month after the T7).
Arguments in favor of the Canon EOS Rebel T7:
- Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
- More affordable: Was released into a lower priced segment (25 percent cheaper at launch).
- More heavily discounted: Has been on the market for longer (launched in February 2018).
If the count of individual advantages (bullet points above) is taken as a guide, the SL3 is the clear winner of the match-up (16 : 3 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 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 SL3 and the Canon T7 place the cameras among the top in their class? Find out in the latest Best DSLR Camera listing 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 partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the SL3 or the T7. 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.
This is why expert reviews are important. The adjacent summary-table relays the overall verdicts of several of the most popular camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, and photographyblog). 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 assessments were made in relation to similar cameras of the same technological generation. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, 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.
