Canon SL1 versus Canon SL2

The Canon EOS Rebel SL1 (called Canon 100D in some regions) and the Canon EOS Rebel SL2 (labelled Canon 200D in some countries) are two digital cameras that were announced, respectively, in March 2013 and June 2017. Both are DSLR (Digital Single Lens Reflex) cameras that are equipped with an APS-C sensor. The SL1 has a resolution of 17.9 megapixel, whereas the SL2 provides 24 MP.

Body comparison

The physical size and weight of the Canon SL1 and the Canon SL2 are illustrated in the side-by-side display below. Three consecutive views from the front, the top, and the rear side are shown. All size dimensions are rounded to the nearest millimeter. You can also use the toggle button to switch to a percentage comparison if you prefer that the measures are being expressed in relative terms (in this case, the camera on the left – the SL1 – represents 100 percent across all the size and weight measures).

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Canon SL2 is considerably larger (106 percent) than the Canon SL1. Moreover, the SL2 is markedly heavier (11 percent) than the SL1. In this context, it is worth noting that neither the SL1 nor the SL2 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 find an overview of suitable optics in the Canon EF Lens Catalog.

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. 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. Alternatively, you can also move across to the CAM-parator tool and choose from the broad selection of possible comparisons there.

The listed prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The two cameras under review were launched at the same price and fall into the same 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.

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. A large sensor will generally have larger individual pixels that offer better low-light sensitivity, provide wider dynamic range, and have 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 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.

Canon SL1 and Canon SL2 sensor measures
Sensor size

While the two cameras under review share the same sensor size, the SL2 offers a higher resolution of 24 megapixel, compared with 17.9 MP of the SL1. This megapixel advantage translates into a 16 percent gain in linear resolution. On the other hand, these sensor specs imply that the SL2 has a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 3.72μm versus 4.31μm for the SL1). However, it should be noted that the SL2 is much more recent (by 4 years and 3 months) than the SL1, and its sensor will have benefitted from technological advances during this time that compensate for the smaller pixel size.

Sensor resolution

Consistent information on actual sensor performance is available from DXO Mark for most 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. Of the two cameras under consideration, the SL2 offers substantially better image quality than the SL1 (overall score 16 points higher). The advantage is based on 1.8 bits higher color depth, 2.1 EV in additional dynamic range, and 0.3 stops in additional low light sensitivity. 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 also of capturing video footage. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, but the SL2 provides a faster frame rate than the SL1. It can shoot movie footage at 1080/60p, while the SL1 is limited to 1080/30p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. The SL1 and the SL2 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 table below summarizes some of the other core capabilities of the Canon SL1 and Canon SL2 in connection with corresponding information for a sample of similar cameras. The full specs-sheets can be found in the camera manual or, for example, in the dpreview camera hub.

The SL2 is a current model that online retailers, such as amazon, will have in stock. In contrast, the SL1 has been discontinued (but it can be found pre-owned on ebay). As a replacement in the same line of cameras, the SL1 was succeeded by the Canon SL2.

Summary

So what is the bottom line? Which of the two cameras – the Canon SL1 or the Canon SL2 – has the upper hand? Below is a summary of the relative strengths of each of the two contestants.


Advantages of the Canon EOS Rebel SL1:

  • More compact: Is smaller (117x91mm vs 122x93mm) and thus needs less room in the bag.
  • Less heavy: Is lighter (by 46g or 10 percent) and hence easier to carry around.
  • More heavily discounted: Has been available for much longer (launched in March 2013).

Reasons to prefer the Canon EOS Rebel SL2:

  • More detail: Has more megapixels (24 vs 17.9MP), which boosts linear resolution by 16%.
  • Better image quality: Scores substantially higher (16 points) in the DXO overall evaluation.
  • Richer colors: Generates noticeably more natural colors (1.8 bits more color depth).
  • More dynamic range: Captures a broader range of light and dark details (2.1 EV of extra DR).
  • Better video: Provides higher movie framerates (1080/60p vs 1080/30p).
  • More flexible LCD: Has swivel screen for odd-angle shots in portrait or landscape orientation.
  • Longer lasting: Gets more shots (650 versus 380) out of a single battery charge.
  • More modern: Reflects 4 years and 3 months of technical progress since the SL1 launch.

If the count of individual advantages (bullet points above) is taken as a guide, the SL2 is the clear winner of the contest (8 : 3 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.

In any case, while the comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it remains partial and cannot reveal, for example, the handling experience and imaging performance when actually working with the SL1 or the SL2. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased. This is why expert reviews are important. The following table reports the overall rankings of the cameras as published by some of the major camera review sites. You can find the full text of the reviews, respectively, at cameralabs.com, dpreview.com, ephotozine.com, imaging-resource.com, and photographyblog.com.

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.
