Canon 50D versus Canon 7D

The Canon EOS 50D and the Canon EOS 7D are two enthusiast cameras that were revealed to the public, respectively, in August 2008 and September 2009. Both are DSLR (Digital Single Lens Reflex) cameras that are equipped with an APS-C sensor. The 50D has a resolution of 15.1 megapixel, whereas the 7D provides 17.9 MP.

Body comparison

The physical size and weight of the Canon 50D and the Canon 7D are illustrated in the side-by-side display below. Three consecutive perspectives from the front, the top, and the back are presented. All width, height and depth measures are rounded to the nearest millimeter. You can also toggle the display 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 50D – 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 is somewhat larger (4 percent) than the Canon 50D. Moreover, the 7D is slightly heavier (5 percent) than the 50D. In this context, it is worth noting that both cameras are splash and dust-proof and can, hence, be used in inclement weather conditions or harsh environments.

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 50D was launched at a somewhat lower price (by 24 percent) than the 7D, 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.

Sensor comparison

The size of the sensor inside a digital camera is one of the key determinants of image quality. All other things equal, a large sensor will have larger individual pixel-units that offer better low-light sensitivity, wider dynamic range, and 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 and have a format factor (sometimes also referred to as "crop factor") of 1.6. Within the spectrum of camera sensors, this places the review cameras among the medium-sized sensor cameras that aim to strike a balance between image quality and portability. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Sensor size

While the two cameras under review share the same sensor size, the 7D offers a higher resolution of 17.9 megapixel, compared with 15.1 MP of the 50D. This megapixel advantage translates into a 9 percent gain in linear resolution. On the other hand, these sensor specs imply that the 7D has a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 4.31μm versus 4.69μm for the 50D). However, it should be noted that the 7D is a somewhat more recent model (by 1 year) than the 50D, and its sensor might have benefitted from technological advances during this time that at least partly compensate for the smaller pixel size.

For most 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. The Overall DXO ratings for the two cameras under consideration are close, suggesting that they provide similar image quality. The adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-cameras.

Many modern cameras are not only capable of taking still images, but can also record movies. The 7D indeed provides for movie recording, while the 50D does not. The highest resolution format that the 7D can use is 1080/30p.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. The 50D and the 7D 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 50D, the Canon 7D, and comparable cameras. If you need more detail on the specs, you can find comprehensive listings, for example, in the dpreview camera hub.

Both the 50D and the 7D have been discontinued, but can regularly be found used on ebay. The 50D was replaced by the Canon 60D, while the 7D was followed by the Canon 7D Mark II.


So what is the bottom line? Which of the two cameras – the Canon 50D or the Canon 7D – has the upper hand? The listing below highlights the relative strengths of the two models.

Advantages of the Canon EOS 50D:

  • More affordable: Was introduced into a lower priced segment (24 percent cheaper at launch).
  • More heavily discounted: Has been on the market for longer (launched in August 2008).

Reasons to prefer the Canon EOS 7D:

  • More detail: Has more megapixels (17.9 vs 15.1MP), which boosts linear resolution by 9%.
  • Broader imaging potential: Can capture not only stills but also 1080/30p video.
  • Faster burst: Shoots at higher frequency (8 vs 6.3 flaps/sec) to capture the decisive moment.
  • More modern: Was introduced somewhat (1 year) more recently.

If the count of relative strengths (bullet points above) is taken as a measure, the 7D emerges as the winner of the match-up (4 : 2 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 technical specifications can provide a useful overview of the capabilities of different cameras, it remains partial and cannot reveal, for example, the handling experience and imaging performance when actually working with the 50D or the 7D. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased. This is where reviews by experts come in. The table below summarizes the assessments of some of the best known camera review sites. The detailed reviews can be accessed, respectively, on the websites of,,,, and

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. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
