Canon 400D versus Canon 7D II

The Canon EOS 400D (called Canon XTi in some regions) and the Canon EOS 7D Mark II are two digital cameras that were officially introduced, respectively, in August 2006 and September 2014. Both are DSLR (Digital Single Lens Reflex) cameras that are equipped with an APS-C sensor. The 400D has a resolution of 10.1 megapixel, whereas the 7D Mark II provides 20 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 400D vs Canon 7D II

The physical size and weight of the Canon 400D and the Canon 7D II 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. You can also use the toggle button to switch to a percentage comparison if you prefer that the measures are being expressed in relative terms (in this case, the camera on the left – the 400D – 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 7D II is considerably larger (56 percent) than the Canon 400D. Moreover, the 7D Mark II is substantially heavier (64 percent) than the 400D. It is noteworthy in this context that the 7D Mark II is splash and dust-proof, while the 400D 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.

Concerning battery life, the 400D gets 370 shots out of its NB-2LH battery, while the 7D Mark II can take 670 images on a single charge of its LP-E6N power pack.

The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives. If you would like to visualize and compare a different camera combination, just use the right or left arrows in the table to switch to the respective camera.

The price is, of course, an important factor in any camera decision. 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 400D was launched at a markedly lower price (by 56 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.

 

Sensor comparison: Canon 400D vs Canon 7D II

The size of the sensor inside a digital camera is one of the key determinants 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 tend to be more expensive and 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 2 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.

Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors.

Canon 400D and Canon 7D II sensor measures

With 20MP, the 7D Mark II offers a higher resolution than the 400D (10.1MP), but the 7D Mark II has smaller individual pixels (pixel pitch of 4.10μm versus 5.71μm for the 400D). Yet, the 7D Mark II is a much more recent model (by 8 years) than the 400D, and its sensor will have benefitted from technological advances during this time that enhance the light gathering capacity of its pixel-units.

The 7D Mark II has on-sensor phase detect pixels, which results in relatively fast and reliable autofocus acquisition during video recording.

400D versus 7D Mark II MP

Consistent information on actual sensor performance is available from DXO Mark for many cameras. 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"). Of the two cameras under consideration, the 7D Mark II has a markedly higher DXO score than the 400D (overall score 8 points higher), which will translate into better image quality. The advantage is based on 0.3 bits higher color depth, 0.8 EV in additional dynamic range, and 0.7 stops in additional low light sensitivity. The following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.

Many modern cameras are not only capable of taking still images, but also of capturing video footage. The 7D Mark II indeed provides for movie recording, while the 400D does not. The highest resolution format that the 7D Mark II can use is 1080/60p.

 

Feature comparison: Canon 400D vs Canon 7D II

Apart from body and sensor, cameras can and do differ across a variety of features. The 400D 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 following table reports on some other key feature differences and similarities of the Canon 400D, the Canon 7D II, and comparable cameras. If you need more detail on the specs, you can find comprehensive listings, for example, in the dpreview camera hub.

One feature that is present on the 7D Mark II, but is missing on the 400D 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 400D writes its imaging data to Compact Flash cards, while the 7D Mark II uses Compact Flash or SDXC cards. The 7D Mark II features dual card slots, which can be very useful in case a memory card fails. In contrast, the 400D only has one slot.

The 7D Mark II is a recent model that features in the current product line-up of Canon. 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.

Review summary: Canon 400D vs Canon 7D II

So what is the bottom line? Is the Canon 400D better than the Canon 7D II or vice versa? Below is a summary of the relative strengths of each of the two contestants.


Arguments in favor of the Canon EOS 400D:

  • More compact: Is smaller (127x84mm vs 149x112mm) and thus needs less room in the bag.
  • Less heavy: Is lighter (by 354g or 39 percent) and hence easier to carry around.
  • More affordable: Was introduced into a lower priced category (56 percent cheaper at launch).
  • More heavily discounted: Has been available for much longer (launched in August 2006).


Reasons to prefer the Canon EOS 7D Mark II:

  • More detail: Has more megapixels (20 vs 10.1MP), which boosts linear resolution by 41%.
  • Better image quality: Scores markedly higher (8 points) in the DXO overall evaluation.
  • More dynamic range: Captures a broader range of light and dark details (0.8 EV of extra DR).
  • Better low-light sensitivity: Can shoot in dim conditions (0.7 stops ISO advantage).
  • Broader imaging potential: Can capture not only stills but also 1080/60p video.
  • Better video autofocus: Features on-sensor phase-detection for more confident movie autofocus.
  • Easier setting verification: Features a control panel on top to check 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).
  • Faster shutter: Has higher mechanical shutter speed (8000/sec vs 4000/sec) to freeze action.
  • Faster burst: Shoots at higher frequency (10 vs 3 flaps/sec) to capture the decisive moment.
  • Longer lasting: Gets more shots (670 versus 370) out of a single battery charge.
  • Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
  • Faster data transfer: Supports a more advanced USB protocol (3.0 vs 2.0).
  • Greater peace of mind: Features a second card slot as a backup in case of memory card failure.
  • More modern: Reflects 8 years of technical progress since the 400D launch.

If the number of relative strengths (bullet points above) is taken as a guide, the 7D Mark II is the clear winner of the contest (16 : 4 points). However, the relevance of individual strengths will vary across photographers, so that you might want to apply your own weighing scheme to the summary points when reflecting and deciding on a new camera.

400D 04:16 7D Mark II

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 400D 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 why expert reviews are important. The adjacent table relays the overall verdicts of several of the most popular camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, photographyblog).

The review scores listed above should be treated 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. A score, therefore, has to be seen in close connection to the price and market introduction time 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. Also, please note that some of the review sites have changed their methodology and reporting over time.
