Canon SL2 versus Canon 77D

The Canon EOS Rebel SL2 (called Canon 200D in some regions) and the Canon EOS 77D are two digital cameras that were revealed to the public, respectively, in June 2017 and February 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. Read on to find out how these two cameras compare with respect to their size, their sensors, their features, and their reception by expert reviewers.

Body comparison: Canon SL2 vs Canon 77D

An illustration of the physical size and weight of the Canon SL2 and the Canon 77D is provided in the side-by-side display below. 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. 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 side – the SL2 – represents the basis for the calculations 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 77D is notably larger (15 percent) than the Canon SL2. Moreover, the 77D is markedly heavier (19 percent) than the SL2. In this context, it is worth noting that neither the SL2 nor the 77D 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 camera comparisons there.

The price is, of course, an important factor in any camera decision. The listed launch 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 39 percent) than the 77D, 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: Canon SL2 vs Canon 77D

The size of the sensor inside a digital camera is one of the key determinants 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. 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.

Canon SL2 and Canon 77D sensor measures

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 SL2 and the 77D have the same pixel density, as well as the same pixel size. It should, however, be noted that the SL2 is a somewhat more recent model (by 4 months) than the 77D, and its sensor might have benefitted from technological advances during this time.

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"). The Overall DXO ratings for the two cameras under consideration are close, suggesting that they provide similar image quality. 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. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, and both provide the same movie specifications (1080/60p).

Feature comparison: Canon SL2 vs Canon 77D

Apart from body and sensor, cameras can and do differ across a range of features. The SL2 and the 77D 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 SL2 and Canon 77D in connection with corresponding information for a sample of similar cameras. If needed, the dpreview camera hub, for example, contains further detail on the cameras' specs.

Both the SL2 and the 77D are current models that good online retailers will have in stock. You can check the latest prices, for example, at amazon. The 77D replaced the earlier Canon T6s, while the SL2 followed on from the Canon SL1.

Review summary: Canon SL2 vs Canon 77D

So what is the bottom line? Which of the two cameras – the Canon SL2 or the Canon 77D – has the upper hand? The listing below highlights the relative strengths of the two models.


Advantages of the Canon EOS Rebel SL2:

  • More compact: Is smaller (122x93mm vs 131x100mm) and thus needs less room in the bag.
  • Less heavy: Is lighter (by 87g or 16 percent) and hence easier to carry around.
  • More affordable: Was introduced into a lower priced category (39 percent cheaper at launch).
  • More modern: Is somewhat more recent (announced 4 months after the 77D).

Reasons to prefer the Canon EOS 77D:

  • Easier setting verification: Has a control panel on top to check shooting parameters.
  • Faster burst: Shoots at higher frequency (6 vs 5 flaps/sec) to capture the decisive moment.
  • More heavily discounted: Has been on the market for longer (launched in February 2017).

If the number of relative strengths (bullet points above) is taken as a guide, the SL2 comes out slightly ahead of the 77D (4 : 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 before making a decision on a new camera.

SL2 04:03 77D

In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it says nothing about, for example, the handling, responsiveness, and overall imaging quality of the SL2 and the 77D in practical situations. 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 where reviews by experts come in. 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.

The above review scores should be interpreted with care, though. The ratings are only valid when refering to cameras in the same category and of the same age. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, 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.
