Canon 77D versus Canon 40D
The Canon EOS 77D and the Canon EOS 40D are two digital cameras that were announced, respectively, in February 2017 and August 2007. 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 40D provides 10.1 MP.
The side-by-side display below illustrates the physical size and weight of the Canon 77D and the Canon 40D. Three consecutive perspectives from the front, the top, and the back are presented. All width, height and depth measures 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 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 40D is notably larger (20 percent) than the Canon 77D. Moreover, the 40D is substantially heavier (52 percent) than the 77D. In this context, it is worth noting that neither the 77D nor the 40D 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 77D was launched at a markedly lower price (by 31 percent) than the 40D, 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. 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 are more costly to manufacture and tent to 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 10.1 MP of the 40D. This megapixel advantage translates into a 54 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 5.73μm for the 40D). In this context, it should be noted, however, that the 77D is much more recent (by 9 years and 5 months) than the 40D, and its sensor will have benefitted from technological advances during this time that compensate for the smaller pixel size.
For most cameras, data on sensor performance has been reported by DXO Mark. This service assesses and scores the color depth ("DXO Portrait"), dynamic range ("DXO Landscape"), and low-light sensitivity ("DXO Sports") of camera sensors, and also publishes an overall camera score. 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 77D indeed provides movie recording capabilities, while the 40D does not. The highest resolution format that the 77D can use is 1080/60p.
Apart from body and sensor, cameras can and do differ across a range of features. The 77D and the 40D 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 77D, the Canon 40D, and comparable cameras. 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 40D has been discontinued (but it can be found pre-owned on ebay). As a replacement in the same line of cameras, the 40D was succeeded by the Canon 50D.
So what is the bottom line? Is there a clear favorite between the Canon 77D and the Canon 77D? The listing below highlights the relative strengths of the two models.
Arguments in favor of the Canon EOS 77D:
- More detail: Offers more megapixels (24 vs 10.1MP) with a 54% higher linear resolution.
- Broader imaging potential: Can record not only still images but also 1080/60p movies.
- More detailed LCD: Has a higher resolution rear screen (1040k vs 230k dots).
- 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.
- More compact: Is smaller (131x100mm vs 146x108mm) and thus needs less room in the bag.
- Less heavy: Is lighter (by 282g or 34 percent) and hence easier to carry around.
- More affordable: Was introduced into a lower priced category (31 percent cheaper at launch).
- More modern: Reflects 9 years and 5 months of technical progress since the 40D launch.
Reasons to prefer the Canon EOS 40D:
- Faster shutter: Has higher mechanical shutter speed (8000/sec vs 4000/sec) to freeze action.
- Longer lasting: Gets more shots (750 versus 600) out of a single battery charge.
- More heavily discounted: Has been around for much longer (launched in August 2007).
If the count of relative strengths (bullet points above) is taken as a measure, the 77D is the clear winner of the match-up (9 : 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.
In any case, while the comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it remains partial and cannot reveal, for example, the handling experience and imaging performance when actually working with the 77D or the 40D. 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 table below summarizes the assessments of some of the best known camera review sites. The full reviews are available, respectively, at 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 are only valid when refering to cameras in the same category and of the same age. 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, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
In case you are interested in seeing how other cameras pair up, just make a corresponding selection in the search boxes below. 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, please contact me, and I will try to update the database with the necessary infos.
