Canon 77D versus Canon 70D

The Canon EOS 77D and the Canon EOS 70D are two digital cameras that were revealed to the public, respectively, in February 2017 and July 2013. Both are DSLR (Digital Single Lens Reflex) cameras that are equipped with an APS-C sensor. The 77D has a resolution of 24 megapixel, whereas the 70D provides 20 MP.

Body comparison

The side-by-side display below illustrates the physical size and weight of the Canon 77D and the Canon 70D. Three successive views from the front, the top, and the rear 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 77D – 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 larger (10 percent) than the Canon 77D. Moreover, the 70D is substantially heavier (40 percent) than the 77D. It is noteworthy in this context that the 70D is splash and dust-proof, while the 77D 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 77D gets 600 shots out of its LP-E17 battery, while the 70D can take 920 images on a single charge of its LP-E6 power pack.

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 77D was launched at a somewhat lower price (by 25 percent) than the 70D, 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. 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 tend to be associated with larger, more expensive camera bodies 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.

Canon 77D and Canon 70D sensor measures
Sensor size

Despite having a slightly smaller sensor, the Canon 77D offers a higher resolution of 24 megapixel, compared with 20 MP of the Canon 70D. 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 4.11μm for the 70D). However, it should be noted that the 77D is much more recent (by 3 years and 7 months) than the 70D, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently.

Consistent information on actual sensor performance is available from DXO Mark for most cameras. 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 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. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the 77D provides a higher frame rate than the 70D. It can shoot video footage at 1080/60p, while the 70D is limited to 1080/30p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. The 77D 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 following table reports on some other key feature differences and similarities of the Canon 77D, the Canon 70D, and comparable cameras. The full specs-sheets can be found in the camera manual or, for example, in the dpreview camera hub.

The 77D is a current model that online retailers, such as amazon, will have in stock. In contrast, the 70D has been discontinued (but it can be found pre-owned on ebay). As a replacement in the same line of cameras, the 70D was succeeded by the Canon 80D.

Summary

So what is the bottom line? Is there a clear favorite between the Canon 77D and the Canon 77D? The listing below highlights the relative strengths of the two models.


Arguments in favor of the Canon EOS 77D:

  • More detail: Offers more megapixels (24 vs 20MP) with a 10% higher linear resolution.
  • Better video: Provides higher movie framerates (1080/60p vs 1080/30p).
  • Less heavy: Is lighter (by 215g or 28 percent) and hence easier to carry around.
  • More affordable: Was introduced into a lower priced segment (25 percent cheaper at launch).
  • More modern: Reflects 3 years and 7 months of technical progress since the 70D launch.

Reasons to prefer the Canon EOS 70D:

  • Faster shutter: Has higher mechanical shutter speed (8000/sec vs 4000/sec) to freeze action.
  • Faster burst: Shoots at higher frequency (7 vs 6 flaps/sec) to capture the decisive moment.
  • Longer lasting: Gets more shots (920 versus 600) out of a single battery charge.
  • Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
  • More heavily discounted: Has been around for much longer (launched in July 2013).

If the count of individual advantages (bullet points above) is taken as a guide, the match-up finishes in a tie (5 points each). 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.

77D 05:05 70D

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 77D or the 70D handle or perform in practice. 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 cameralabs.com, dpreview.com, ephotozine.com, imaging-resource.com, and photographyblog.com.

The review scores listed above should be treated with care, though. The assessments were made in relation to similar cameras of the same technological generation. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, 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.
