Canon 7D versus Canon 70D
The Canon EOS 7D and the Canon EOS 70D are two enthusiast cameras that were revealed to the public, respectively, in September 2009 and July 2013. Both are DSLR (Digital Single Lens Reflex) cameras that are equipped with an APS-C sensor. The 7D has a resolution of 17.9 megapixel, whereas the 70D provides 20 MP.
An illustration of the physical size and weight of the Canon 7D and the Canon 70D is provided in the side-by-side display below. Three consecutive perspectives from the front, the top, and the back are presented. All size 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 7D – 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 70D is notably smaller (12 percent) than the Canon 7D. Moreover, the 70D is markedly lighter (12 percent) than the 7D. 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 70D was launched at a markedly lower price (by 29 percent) than the 7D, 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.
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. Further, a large sensor camera will give the photographer additional creative options when using shallow depth-of-field to isolate a subject from its 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 70D 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.
With 20MP, the 70D offers a higher resolution than the 7D (17.9MP), but the 70D has smaller individual pixels (pixel pitch of 4.11μm versus 4.31μm for the 7D). Yet, the 70D is a much more recent model (by 3 years and 10 months) than the 7D, and its sensor will have benefitted from technological advances during this time that enhance the light gathering capacity of its pixel-units.
For most 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"). 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 also of capturing video footage. 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 (1080/30p).
Apart from body and sensor, cameras can and do differ across a range of features. The 7D and the 70D 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 7D and Canon 70D along with similar information for a selection of comparators. The full specs-sheets can be found in the camera manual or, for example, in the dpreview camera hub.

Both the 7D and the 70D have been discontinued, but can regularly be found used on ebay. The 7D was replaced by the Canon 7D Mark II, while the 70D was followed by the Canon 80D.
So how do things add up? Which of the two cameras – the Canon 7D or the Canon 70D – has the upper hand? The listing below highlights the relative strengths of the two models.
Advantages of the Canon EOS 7D:
- Faster burst: Shoots at higher frequency (8 vs 7 flaps/sec) to capture the decisive moment.
- More heavily discounted: Has been available for much longer (launched in September 2009).
Arguments in favor of the Canon EOS 70D:
- More detail: Has more megapixels (20 vs 17.9MP), which boosts linear resolution by 6%.
- 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.
- More compact: Is smaller (139x104mm vs 148x111mm) and will fit more readily into a bag.
- Less heavy: Has a lower weight (by 105g or 12 percent) and is thus easier to take along.
- Longer lasting: Gets more shots (920 versus 800) out of a single battery charge.
- More affordable: Was introduced into a lower priced category (29 percent cheaper at launch).
- More modern: Reflects 3 years and 10 months of technical progress since the 7D launch.
If the count of relative strengths (bullet points above) is taken as a measure, the 70D is the clear winner of the contest (9 : 2 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.
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 7D or the 70D 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. The full reviews are available, respectively, at cameralabs.com, dpreview.com, ephotozine.com, imaging-resource.com, and photographyblog.com.

The above review scores should be interpreted with care, though. The assessments were made in relation to similar cameras of the same technological generation. 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. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
