Canon T6i versus Canon SL2

The Canon EOS Rebel T6i (called Canon 750D in some regions) and the Canon EOS Rebel SL2 (labelled Canon 200D in some countries) are two digital cameras that were announced, respectively, in February 2015 and June 2017. Both are DSLR (Digital Single Lens Reflex) cameras that are equipped with an APS-C sensor. Both cameras offer a resolution of 24 megapixel.

Body comparison

The side-by-side display below illustrates the physical size and weight of the Canon T6i and the Canon SL2. 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. You can also toggle the display 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 T6i – 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 notably smaller (15 percent) than the Canon T6i. Moreover, the SL2 is markedly lighter (18 percent) than the T6i. In this context, it is worth noting that neither the T6i 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 SL2 was launched at a markedly lower price (by 27 percent) than the T6i, 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.

Sensor comparison

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.

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.

Sensor size

The two cameras under review do not only share the same sensor size, but also offer an identical resolution of 24 megapixel. This similarity in sensor specs implies that both the T6i and the SL2 have the same pixel density, as well as the same pixel size. It should, however, be noted that the SL2 is much more recent (by 2 years and 4 months) than the T6i, and its sensor will have benefitted from technological advances during this time.

Sensor resolution

Consistent information on actual sensor performance is available from DXO Mark for most cameras. 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"). Of the two cameras under consideration, the SL2 has a markedly higher DXO score than the T6i (overall score 8 points higher), which will translate into better image quality. The advantage is based on 0.9 bits higher color depth, 1.4 EV in additional dynamic range, and 0.2 stops in additional low light sensitivity. 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. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, and both provide the same movie specifications (1080/60p).

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. The T6i 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 following table reports on some other key feature differences and similarities of the Canon T6i, the Canon SL2, and comparable cameras. If you need more detail on the specs, you can find comprehensive listings, 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 T6i has been discontinued (but it can be found pre-owned on ebay). As a replacement in the same line of cameras, the T6i was succeeded by the Canon T7i.

Summary

So what is the bottom line? Is the Canon T6i better than the Canon SL2 or vice versa? Below is a summary of the relative strengths of each of the two contestants.


Arguments in favor of the Canon EOS Rebel T6i:

  • More heavily discounted: Has been available for much longer (launched in February 2015).

Reasons to prefer the Canon EOS Rebel SL2:

  • Better image quality: Scores markedly higher (8 points) in the DXO overall evaluation.
  • More dynamic range: Captures a broader range of light and dark details (1.4 EV of extra DR).
  • More compact: Is smaller (122x93mm vs 132x101mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight (by 102g or 18 percent) and is thus easier to take along.
  • Longer lasting: Gets more shots (650 versus 440) out of a single battery charge.
  • More affordable: Was introduced into a lower priced category (27 percent cheaper at launch).
  • More modern: Reflects 2 years and 4 months of technical progress since the T6i launch.

If the number of relative strengths (bullet points above) is taken as a guide, the SL2 is the clear winner of the contest (7 : 1 points). However, the pertinence of the various camera strengths will differ across photographers, so that you might want to weigh individual camera traits according to their importance for your own imaging needs.

T6i 01:07 SL2

In any case, while the specs-based evaluation of cameras is instructive in revealing their potential as photographic tools, it remains incomplete and does no justice, for example, to the way the T6i or the SL2 handle or perform in practice. At times, user reviews, such as those published at amazon, address these issues in a useful manner, but such feedback is on many occasions incomplete, inconsistent, and unreliable. This is why expert reviews are important. The adjacent table relays the overall verdicts of several of the most popular camera review sites. The full reviews are available, respectively, at cameralabs.com, dpreview.com, ephotozine.com, imaging-resource.com, and photographyblog.com.

Care should be taken when interpreting the review scores above, though. The ratings are only valid when refering 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.
