Canon 77D versus Canon 400D
The Canon EOS 77D and the Canon 400D (labelled Canon XTi in some countries) are two digital cameras that were announced, respectively, in February 2017 and August 2006. 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 400D provides 10.1 MP.
An illustration of the physical size and weight of the Canon 77D and the Canon 400D is provided in the side-by-side display below. Three successive views from the front, the top, and the rear are shown. All width, height and depth 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 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 400D is considerably smaller (80 percent) than the Canon 77D. However, the 400D is slightly heavier (3 percent) than the 77D. In this context, it is worth noting that neither the 77D nor the 400D 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 400D was launched at a somewhat lower price (by 11 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.
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. 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 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, but their sensors differ slightly in size. The sensor area in the 400D is 1 percent smaller. They nevertheless have the same format factor of 1.6. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.
With 24MP, the 77D offers a higher resolution than the 400D (10.1MP), but the 77D has smaller individual pixels (pixel pitch of 3.72μm versus 5.71μm for the 400D). However, the 77D is a somewhat more recent model (by 10 years and 5 months) than the 400D, and its sensor might have benefitted from technological advances during this time that enhance the light gathering capacity of its pixels.
Consistent information on actual sensor performance is available from DXO Mark for most cameras. 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 cannot only take still pictures, but also record videos. The 77D indeed provides movie recording capabilities, while the 400D 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 400D 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 400D, 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 400D has been discontinued (but it can be found pre-owned on ebay). As a replacement in the same line of cameras, the 400D was succeeded by the Canon 450D.
So how do things add up? Is the Canon 77D better than the Canon 400D or vice versa? A synthesis of the relative strong points of each of the models is listed below.
Reasons to prefer 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.
- Easier setting verification: Has an LCD display on top to control shooting parameters.
- Larger screen: Has a bigger rear LCD (3.0" vs 2.5") for image review and settings control.
- 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.
- Faster burst: Shoots at higher frequency (6 vs 3 flaps/sec) to capture the decisive moment.
- Longer lasting: Can take more shots (600 versus 370) on a single battery charge.
- More modern: Reflects 10 years and 5 months of technical progress since the 400D launch.
Arguments in favor of the Canon 400D:
- More compact: Is smaller (127x84mm vs 131x100mm) and will fit more readily into a bag.
- More affordable: Was released into a lower priced segment (11 percent cheaper at launch).
- More heavily discounted: Has been around for much longer (launched in August 2006).
If the number of relative strengths (bullet points above) is taken as a guide, the 77D is the clear winner of the match-up (10 : 3 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 400D in practical situations. User reviews that are available, for instance, at amazon can sometimes shed light on these issues, but such feedback is all too often partial, inconsistent, and inaccurate. This is why hands-on reviews by experts are important. The adjacent table relays the overall verdicts of several of the most popular 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 above review scores should be interpreted 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 comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
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 cannot find the camera you are interested in, please send me an email, and I will try to add information on that model to the database.
