Canon 77D versus Canon 100D
The Canon EOS 77D and the Canon EOS 100D (labelled Canon SL1 in some countries) are two digital cameras that were revealed to the public, respectively, in February 2017 and March 2013. 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 100D provides 17.9 MP.
The physical size and weight of the Canon 77D and the Canon 100D are illustrated in the side-by-side display below. Three successive views from the front, the top, and the rear are shown. All size 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 77D – represents the basis or 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 100D is notably smaller (19 percent) than the Canon 77D. Moreover, the 100D is markedly lighter (25 percent) than the 77D. In this context, it is worth noting that neither the 77D nor the 100D 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 100D 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.
The imaging sensor is at the core of digital cameras and its size is one of the main determining factors 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. Further, a large sensor camera will give the photographer additional creative options when using shallow depth-of-field to isolate a subject from its 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.
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 100D. 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 100D). In this context, it should be noted, however, that the 77D is much more recent (by 3 years and 10 months) than the 100D, and its sensor will have benefitted from technological advances during this time that compensate for the smaller pixel size.
Consistent information on actual sensor performance is available from DXO Mark for most cameras. This service determines an overall sensor rating, as well as sub-scores for low-light sensitivity ("DXO Sports"), dynamic range ("DXO Landscape"), and color depth ("DXO Portrait"). The adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-cameras.

Many modern cameras are not only capable of taking still images, but also of capturing video footage. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the 77D provides a higher frame rate than the 100D. It can shoot video footage at 1080/60p, while the 100D is limited to 1080/30p.
Apart from body and sensor, cameras can and do differ across a variety of features. The 77D and the 100D 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 adjacent table lists some of the other core features of the Canon 77D and Canon 100D along with similar information for a selection of comparators. If needed, the dpreview camera hub, for example, contains further detail on the cameras' specs.

The 77D is a current model that online retailers, such as amazon, will have in stock. In contrast, the 100D has been discontinued (but it can be found pre-owned on ebay). As a replacement in the same line of cameras, the 100D was succeeded by the Canon 200D.
So what conclusions can be drawn? Is the Canon 77D better than the Canon 100D or vice versa? The listing below highlights the relative strengths of the two models.
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.
- Faster burst: Shoots at higher frequency (6 vs 4.9 flaps/sec) to capture the decisive moment.
- Longer lasting: Can take more shots (600 versus 380) on a single battery charge.
- More modern: Reflects 3 years and 10 months of technical progress since the 100D launch.
Arguments in favor of the Canon EOS 100D:
- More compact: Is smaller (117x91mm vs 131x100mm) and will fit more readily into a bag.
- Less heavy: Has a lower weight (by 133g or 25 percent) and is thus easier to take along.
- More affordable: Was introduced into a lower priced category (39 percent cheaper at launch).
- More heavily discounted: Has been around for much longer (launched in March 2013).
If the number of relative strengths (bullet points above) is taken as a guide, the 77D emerges as the winner of the contest (7 : 4 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.
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 77D and the 100D 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 why expert reviews 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.

Care should be taken when interpreting the review scores above, 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 rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, please note that some of the review sites have changed their methodology and reporting over time.

There is also a set of direct links to comparison reviews that other users of the CAM-parator app explored. If you do not see the camera that you are looking for, kindly get in touch, and I will try to add information on that model to the database.
