Canon 77D versus Canon 550D

The Canon EOS 77D and the Canon EOS 550D (labelled Canon XS in some countries) are two digital cameras that were officially introduced, respectively, in February 2017 and February 2010. Both are DSLR (Digital Single Lens Reflex) cameras that are equipped with an APS-C sensor. The 77D has a resolution of 24 megapixel, whereas the 550D provides 17.9 MP.

Body comparison

The physical size and weight of the Canon 77D and the Canon 550D are illustrated in the side-by-side display below. Three consecutive perspectives from the front, the top, and the back are presented. All size dimensions are rounded to the nearest millimeter. If you prefer, you can also use the toggle button to switch to a comparison in percentage terms (in this case, the camera on the left – the 77D – 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 550D is considerably smaller (96 percent) than the Canon 77D. Moreover, the 550D is slightly lighter (2 percent) than the 77D. In this context, it is worth noting that neither the 77D nor the 550D 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 550D was launched at a somewhat lower price (by 22 percent) than the 77D, which makes it more attractive for photographers on a tight budget. 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 sensor inside a digital camera is one of the key determinants 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. 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.

Canon 77D and Canon 550D sensor measures
Sensor size

While the two cameras under review share the same sensor size, the 77D offers a higher resolution of 24 megapixel, compared with 17.9 MP of the 550D. This megapixel advantage translates into a 16 percent gain in linear resolution. On the other hand, these sensor specs imply that the 77D 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 550D). In this context, it should be noted, however, that the 77D is much more recent (by 7 years) than the 550D, 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 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 two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the 77D provides a higher frame rate than the 550D. It can shoot video footage at 1080/60p, while the 550D is limited to 1080/30p.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. The 77D and the 550D 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 77D and Canon 550D in connection with corresponding information for a sample of similar cameras. If you need more detail on the specs, you can find comprehensive listings, for example, in the dpreview camera hub.

The 77D is a current model that online retailers, such as amazon, will have in stock. In contrast, the 550D has been discontinued (but it can be found pre-owned on ebay). As a replacement in the same line of cameras, the 550D was succeeded by the Canon 600D.

Summary

So what is the bottom line? Is there a clear favorite between the Canon 77D and the Canon 77D? A synthesis of the relative strong points of each of the models is listed below.


Advantages of the Canon EOS 77D:

  • More detail: Offers more megapixels (24 vs 17.9MP) with a 16% higher linear resolution.
  • Better video: Provides higher movie framerates (1080/60p vs 1080/30p).
  • Easier setting verification: Has an LCD display on top to control shooting parameters.
  • More flexible LCD: Has 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.
  • Faster burst: Shoots at higher frequency (6 vs 3.7 flaps/sec) to capture the decisive moment.
  • Longer lasting: Can take more shots (600 versus 440) on a single battery charge.
  • More modern: Reflects 7 years of technical progress since the 550D launch.

Reasons to prefer the Canon EOS 550D:

  • More compact: Is smaller (129x98mm vs 131x100mm) and will fit more readily into a bag.
  • More affordable: Was released into a lower priced segment (22 percent cheaper at launch).
  • More heavily discounted: Has been around for much longer (launched in February 2010).

If the number of relative strengths (bullet points above) is taken as a guide, the 77D is the clear winner of the match-up (8 : 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.

77D 08:03 550D

In any case, while the specs-based evaluation of cameras is instructive in revealing their potential as photographic tools, it remains partial and cannot reveal, for example, the handling experience and imaging performance when actually working with the 77D or the 550D. 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 hands-on reviews by experts are important. The table below summarizes the assessments of some of the best known camera review sites. The detailed reviews can be accessed, respectively, on the websites of cameralabs.com, dpreview.com, ephotozine.com, imaging-resource.com, and photographyblog.com.

The review scores listed above should be treated 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. 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, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
