Canon 5D Mark II versus Canon 800D

The Canon EOS 5D Mark II and the Canon EOS 800D (labelled Canon T7i in some countries) are two digital cameras that were revealed to the public, respectively, in September 2008 and February 2017. Both are DSLR (Digital Single Lens Reflex) cameras that are based on a full frame (5D Mark II) and an APS-C (800D) sensor. The 5D Mark II has a resolution of 21 megapixel, whereas the 800D provides 24 MP. Read on to find out how these two cameras compare with respect to their size, their sensors, their features, and their reception by expert reviewers.

Body comparison: Canon 5D Mark II vs Canon 800D

The physical size and weight of the Canon 5D Mark II and the Canon 800D are illustrated in the side-by-side display below. The two cameras are presented according to their relative size. Three consecutive views from the front, the top, and the rear side 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 5D Mark II – 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 800D is notably smaller (24 percent) than the Canon 5D Mark II. Moreover, the 800D is substantially lighter (37 percent) than the 5D Mark II. It is worth mentioning in this context that the 5D Mark II is splash and dust resistant, 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. A larger imaging sensor (as in the 5D Mark II) will tend to go along with bigger and heavier lenses, while more compact options are available for the smaller-sensor camera (800D). You can find a comprehensive overview of suitable optics in the Canon EF Lens Catalog.

Concerning battery life, the 5D Mark II gets 850 shots out of its LP-E6 battery, while the 800D can take 600 images on a single charge of its LP-E17 power pack.

The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones.

The camera’s price is obviously a critical decision-making factor. The listed launch 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 79 percent) than the 5D 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.

 

Sensor comparison: Canon 5D Mark II vs Canon 800D

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 tend to be associated with larger, more expensive camera bodies and lenses.

Of the two cameras under consideration, the Canon 5D Mark II features a full frame sensor and the Canon 800D an APS-C sensor. The sensor area in the 800D is 62 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.0 and 1.6. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Canon 5D Mark II and Canon 800D sensor measures

Despite having a smaller sensor, the 800D offers a higher resolution of 24 megapixel, compared with 21 MP of the 5D Mark 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 6.41μm for the 5D Mark II). However, it should be noted that the 800D is much more recent (by 8 years and 5 months) than the 5D Mark II, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently.

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").

Many modern cameras cannot only take still pictures, but also record videos. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the 800D provides a faster frame rate than the 5D Mark II. It can shoot movie footage at 1080/60p, while the 5D Mark II is limited to 1080/30p.

 

Feature comparison: Canon 5D Mark II vs Canon 800D

Apart from body and sensor, cameras can and do differ across a variety of features. The 5D Mark II and the 800D 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 5D Mark II, the Canon 800D, and comparable cameras.

The 800D is a current model that online retailers, such as amazon, will have in stock. In contrast, the 5D Mark II has been discontinued (but it can be found pre-owned on eBay). As a replacement in the same line of cameras, the 5D Mark II was succeeded by the Canon 5D Mark III.

Review summary: Canon 5D Mark II vs Canon 800D

So what conclusions can be drawn? Which of the two cameras – the Canon 5D Mark II or the Canon 800D – has the upper hand? Below is a summary of the relative strengths of each of the two contestants.


Arguments in favor of the Canon EOS 5D Mark II:

  • Easier setting verification: Has an LCD display on top to control shooting parameters.
  • Faster shutter: Has higher mechanical shutter speed (8000/sec vs 4000/sec) to freeze action.
  • Longer lasting: Can take more shots (850 versus 600) on a single battery charge.
  • Better sealing: Is weather sealed to enable shooting in dusty or wet environments.
  • More heavily discounted: Has been available for much longer (launched in September 2008).


Reasons to prefer the Canon EOS 800D:

  • More detail: Has more megapixels (24 vs 21MP), which boosts linear resolution by 7%.
  • Better video: Provides higher movie framerates (1080/60p versus 1080/30p).
  • More detailed LCD: Has a higher resolution rear screen (1040k vs 920k dots).
  • More flexible LCD: Has swivel screen for odd-angle shots in portrait or landscape orientation.
  • Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
  • Faster burst: Shoots at higher frequency (6 vs 3.9 flaps/sec) to capture the decisive moment.
  • More compact: Is smaller (131x100mm vs 152x114mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight (by 318g or 37 percent) and is thus easier to take along.
  • Easier fill-in: Has a small integrated flash to brighten shadows of backlit subjects.
  • More affordable: Was introduced into a lower priced category (79 percent cheaper at launch).
  • More modern: Reflects 8 years and 5 months of technical progress since the 5D Mark II launch.

If the count of relative strengths (bullet points above) is taken as a measure, the 800D is the clear winner of the contest (11 : 5 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.

5D Mark II 05:11 800D

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 5D Mark II or the 800D 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 table below summarizes the assessments of some of the best known camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, photographyblog).

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. 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. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
