Body comparison: Canon 100D vs 77D
The physical size and weight of the Canon 100D and the Canon 77D are illustrated in the side-by-side display below. The two cameras are presented according to their relative size. Three successive views from the front, the top, and the rear are shown. All width, height and depth measures are rounded to the nearest millimeter.
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 (23 percent) than the Canon 100D. Moreover, the 77D is markedly heavier (33 percent) than the 100D. In this context, it is worth noting that neither the 100D 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 compare the optics available in the Canon EF Lens Catalog.

Any camera decision will obviously take relative prices into account. The manufacturer’s suggested retail prices give an idea on the placement of the camera in the maker’s lineup and the broader market. 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.
Sensor comparison: Canon 100D vs 77D
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. 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.
Technology-wise, the 77D uses a more advanced image processing engine (DIGIC 7) than the 100D (DIGIC 5), with benefits for noise reduction, color accuracy, and processing speed.
While the two cameras under review share the same sensor size, the 77D offers a higher resolution of 24 megapixels, compared with 17.9 MP of the 100D. This megapixels 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). However, it should be noted 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.
The Canon EOS 100D has a native sensitivity range from ISO 100 to ISO 12800, which can be extended to ISO 100-25600. The corresponding ISO settings for the Canon EOS 77D are ISO 100 to ISO 25600, with the possibility to increase the ISO range to 100-51200..
For many cameras, data on sensor performance has been reported by DXO Mark. 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"). Of the two cameras under consideration, the 77D offers substantially better image quality than the 100D (overall score 15 points higher). The advantage is based on 1.8 bits higher color depth, 2 EV in additional dynamic range, and 0.2 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 can also record movies. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the 77D provides a faster frame rate than the 100D. It can shoot movie footage at 1080/60p, while the 100D is limited to 1080/30p.
Feature comparison: Canon 100D vs 77D
Beyond body and sensor, cameras can and do differ across a range of features. The 100D 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 100D and Canon 77D in connection with corresponding information for a sample of similar cameras.

One feature that is present on the 77D, but is missing on the 100D is a top-level LCD. While being, of course, smaller than the rear screen, the control panel conveys some of the essential shooting information and can be convenient for quick and easy settings verification.The 77D has an articulated screen that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in taking selfies. In contrast, the 100D does not have a selfie-screen.
Concerning the storage of imaging data, both the 100D and the 77D write their files to SDXC cards.
Connectivity comparison: Canon 100D vs 77D
For some imaging applications, the extent to which a camera can communicate with its environment can be an important aspect in the camera decision process. The table below provides an overview of the connectivity of the Canon EOS 100D and Canon EOS 77D and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the 77D offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the 100D does not offer wifi capability.
The 77D is a recent model that features in the current product line-up of Canon. 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.
Review summary: Canon 100D vs 77D
So what is the bottom line? Which of the two cameras – the Canon 100D or the Canon 77D – has the upper hand? The listing below highlights the relative strengths of the two models.
Reasons to prefer the Canon EOS 100D:
- More compact: Is smaller (117x91mm vs 131x100mm) and thus needs less room in the bag.
- Less heavy: Is lighter (by 133g or 25 percent) and hence easier to carry around.
- More affordable: Was introduced into a lower priced category (39 percent cheaper at launch).
- More heavily discounted: Has been available for much longer (launched in March 2013).
Advantages of the Canon EOS 77D:
- More detail: Has more megapixels (24 vs 17.9MP), which boosts linear resolution by 16%.
- Better image quality: Scores substantially higher (15 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 EV of extra DR).
- Better jpgs: Has a more modern image processing engine (DIGIC 7 vs DIGIC 5).
- Better video: Provides higher movie framerates (1080/60p versus 1080/30p).
- Easier setting verification: Features a control panel on top to check shooting parameters.
- More flexible LCD: Has swivel screen for odd-angle shots in portrait or landscape orientation.
- More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
- Faster burst: Shoots at higher frequency (6 vs 4.9 flaps/sec) to capture the decisive moment.
- Longer lasting: Gets more shots (600 versus 380) out of a single battery charge.
- Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
- Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
- Easier wireless transfer: Supports Bluetooth for image sharing without cables.
- More modern: Reflects 3 years and 10 months of technical progress since the 100D launch.
If the number of relative strengths (bullet points above) is taken as a guide, the 77D is the clear winner of the contest (15 : 4 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.
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 100D or the 77D handle or perform in practice. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased.

The review scores listed above should be treated with care, though. The ratings are only valid when referring 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.
