The listed prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The Canon SL3 was launched in the US market at a price of $599. 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 with a 35mm slide

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.

The Canon SL3 features an APS-C sensor and has a format factor (sometimes also referred to as "crop factor") of 1.6. Within the spectrum of camera sensors, this places the Canon SL3 among the medium-sized sensor cameras that aim to strike a balance between image quality and portability.

Canon SL3 sensor measures

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. This service is based on lab testing and assigns an overall score to each camera sensor, as well as ratings for dynamic range ("DXO Landscape"), color depth ("DXO Portrait"), and low-light sensitivity ("DXO Sports"). 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 cannot only take still pictures, but also record videos. The SL3 indeed provides movie recording capabilities. The highest resolution format that the SL3 can use is 4K/25p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. For example, the SL3 has an optical viewfinder that provides a field of view of 95% and a magnification of 0.54x. The following tables report on some other key feature differences and similarities of the Canon SL3 and comparable cameras.

One convenient feature of the SL3 is the presence of an on-board flash. While this built-in flash is not very powerful, it can at times be useful as a fill-in light to brighten deep shadow areas.

Connection 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 EOS Rebel SL3 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. Such an external microphone input can help to substantially improve the quality of audio recordings when a good external microphone is used.

Expert reviews

While the comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it says nothing about, for example, the handling, responsiveness, and overall imaging quality of the SL3 in practical situations. 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 table below summarizes the assessments of some of the best known camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, photographyblog).

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

Care should be taken when interpreting the review scores above, though. The ratings are only valid when referring to cameras in the same category and of the same age. Hence, a score should always be seen in the context of the camera's market launch date and its price, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. It should also be noted that some of the review sites have over time altered the way they render their verdicts.

Canon SL3 FAQ

Below are some additional questions and answers concerning some particular features of the SL3.

What is the technology behind the imaging sensor in the SL3?

The camera has a CMOS (Complementary Metal–Oxide–Semiconductor) sensor at its core.

Which image processing chip is used to convert the raw signal into an image file and perform noise reduction and image sharpening?

Canon equipped the SL3 with the DIGIC 8 image processor.

What is the ISO sensitivity range of the SL3?

The camera has a native sensitivity range from ISO 100 to ISO 25600.

Does the camera have a selfie-friendly screen?

Yes, the LCD-screen of the SL3 is flexible and can be turned to be front-facing for capturing selfies.

What is the life expectancy of the shutter in the Canon EOS Rebel SL3?

Canon mentions a shutter rating of 100 000 actuations for the SL3. This number represents a Mean Time before Failure, that is an average value. The shutter might fail earlier, or it might last longer. Anyway, in order to exhaust the expected shutter life of the SL3 over, say, three years, one would have to take about 100 pictures each and every day.

Do I need to purchase an external camera trigger to shoot time-lapse sequences?

No, the Canon EOS Rebel SL3 has an intervalometer built-in, so that low frequency shooting (for example, flower blooming, sunset, moon rise) can be undertaken without the need to purchase a separate external intervalometer and related software.

What is the fastest shutter speed that can be used with flash?

The SL3's flash sync speed is 1/200 sec.

Does the Canon SL3 support the Ultra High Speed (UHS) bus interface for SD cards?

Yes, the camera can indeed use UHS-I cards (data transfer speed of up to 104 MB/s).

Which battery does the SL3 use?

The camera gets its power from the LP-E17 (here at amazon), which is a rechargeable Lithium-Ion power pack.

Is there a vertical grip available for the SL3?

Canon does not offer an optional battery grip, but third party suppliers do (see here on eBay).
