Canon 800D versus Canon 7D II

The Canon EOS800D (called Canon T7i in some regions) and the Canon EOS 7D Mark II are two digital cameras that were announced, respectively, in February 2017 and September 2014. Both are DSLR (Digital Single Lens Reflex) cameras that are equipped with an APS-C sensor. The 800D has a resolution of 24 megapixel, whereas the 7D Mark II provides 20 MP.

Body comparison

The side-by-side display below illustrates the physical size and weight of the Canon 800D and the Canon 7D II. Three consecutive perspectives from the front, the top, and the back are presented. 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 800D – 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 7D II is notably larger (27 percent) than the Canon 800D. Moreover, the 7D Mark II is substantially heavier (71 percent) than the 800D. It is noteworthy in this context that the 7D Mark II is splash and dust-proof, while the 800D does not feature any corresponding weather-sealing.

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 800D was launched at a markedly lower price (by 58 percent) than the 7D Mark II, 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.

Sensor comparison

The size of the imaging sensor is a crucial determinant 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 7D Mark II is 1 percent bigger. 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.

Sensor size

Despite having a slightly smaller sensor, the Canon 800D offers a higher resolution of 24 megapixel, compared with 20 MP of the Canon 7D II. This megapixel advantage comes at the cost of a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 3.72μm versus 4.10μm for the 7D Mark II). However, it should be noted that the 800D is much more recent (by 2 years and 5 months) than the 7D Mark II, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently.

For most cameras, data on sensor performance has been reported by DXO Mark. 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 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. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, and both provide the same movie specifications (1080/60p).

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. The 800D and the 7D Mark II 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 800D and Canon 7D II along with similar information for a selection of comparators. If you need more detail on the specs, you can find comprehensive listings, for example, in the dpreview camera hub.

Both the 800D and the 7D Mark II are current models that good online retailers will have in stock. You can check the latest prices, for example, at amazon. The 7D Mark II replaced the earlier Canon 7D, while the 800D followed on from the Canon 750D.

Summary

So what is the bottom line? Which of the two cameras – the Canon 800D or the Canon 7D II – has the upper hand? A synthesis of the relative strong points of each of the models is listed below.


Arguments in favor of the Canon EOS800D:

  • More detail: Offers more megapixels (24 vs 20MP) with a 10% higher linear resolution.
  • 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 149x112mm) and thus needs less room in the bag.
  • Less heavy: Is lighter (by 378g or 42 percent) and hence easier to carry around.
  • More affordable: Was introduced into a lower priced category (58 percent cheaper at launch).
  • More modern: Reflects 2 years and 5 months of technical progress since the 7D Mark II launch.

Advantages of the Canon EOS 7D Mark II:

  • Easier setting verification: Has a control panel on top to check shooting parameters.
  • Faster shutter: Has higher mechanical shutter speed (8000/sec vs 4000/sec) to freeze action.
  • Faster burst: Shoots at higher frequency (10 vs 6 flaps/sec) to capture the decisive moment.
  • Longer lasting: Gets more shots (670 versus 600) out of a single battery charge.
  • Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
  • More heavily discounted: Has been around for much longer (launched in September 2014).

If the count of relative strengths (bullet points above) is taken as a measure, the 800D comes out slightly ahead of the 7D Mark II (7 : 6 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 incomplete and does no justice, for example, to the way the 800D or the 7D Mark II handle or perform in practice. 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 where reviews by experts come in. 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 review scores listed above should be treated with care, though. The assessments were made in relation to similar cameras of the same technological generation. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, and comparisons of ratings among very different cameras or across long time periods have little meaning. Also, please note that some of the review sites have changed their methodology and reporting over time.
