Body comparison: Canon 40D vs 7D Mark II
The side-by-side display below illustrates the physical size and weight of the Canon 40D and the Canon 7D II. 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 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 side – the 40D – represents the basis for the calculations 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 (6 percent) than the Canon 40D. Moreover, the 7D Mark II is markedly heavier (11 percent) than the 40D. It is noteworthy in this context that the 7D Mark II is splash and dust-proof, while the 40D 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 compare the optics available 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 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. Alternatively, you can also navigate to the CAM-parator app and make your selection from the full list of cameras there.

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 40D was launched at a markedly lower price (by 28 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 40D vs 7D Mark 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 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.
In terms of underlying technology, both cameras are build around CMOS sensors.
With 20MP, the 7D Mark II offers a higher resolution than the 40D (10.1MP), but the 7D Mark II has smaller individual pixels (pixel pitch of 4.10μm versus 5.73μm for the 40D). Yet, the 7D Mark II is a much more recent model (by 7 years) than the 40D, 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 fast and reliable autofocus acquisition even during video recording.
The Canon EOS 40D has a native sensitivity range from ISO 100 to ISO 1600, which can be extended to ISO 100-3200. The corresponding ISO settings for the Canon EOS 7D Mark II are ISO 100 to ISO 16000, with the possibility to increase the ISO range to 100-51200..
For many 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. Of the two cameras under consideration, the 7D Mark II has a markedly higher DXO score than the 40D (overall score 6 points higher), which will translate into better image quality. The advantage is based on 0.3 bits higher color depth, 0.5 EV in additional dynamic range, and 0.6 stops in additional low light sensitivity. The adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-cameras.

The 7D Mark II is a recent model that features in the current product line-up of Canon. 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.
Review summary: Canon 40D vs 7D Mark II
So how do things add up? Is the Canon 40D better than the Canon 7D II or vice versa? The listing below highlights the relative strengths of the two models.
Reasons to prefer the Canon EOS 40D:
- Less heavy: Is lighter (by 88g or 10 percent) and hence easier to carry around.
- Longer lasting: Can take more shots (750 versus 670) on a single battery charge.
- More affordable: Was introduced into a lower priced category (28 percent cheaper at launch).
- More heavily discounted: Has been available for much longer (launched in August 2007).
Arguments in favor of 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 (6 points) in the DXO overall evaluation.
- Better low-light sensitivity: Can shoot in dim conditions (0.6 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.
- More detailed LCD: Has a higher resolution rear screen (1040k vs 230k dots).
- Faster burst: Shoots at higher frequency (10 vs 6.5 flaps/sec) to capture the decisive moment.
- 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 7 years of technical progress since the 40D launch.
If the count of relative strengths (bullet points above) is taken as a measure, the 7D Mark II is the clear winner of the contest (11 : 4 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.
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 40D or the 7D Mark II handle or perform in practice. 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.

Care should be taken when interpreting the review scores above, 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 comparisons of ratings among very different cameras or across long time periods have little meaning. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
