Canon 30D versus Canon 77D

The Canon EOS 30D and the Canon EOS 77D are two digital cameras that were officially introduced, respectively, in February 2006 and February 2017. Both are DSLR (Digital Single Lens Reflex) cameras that are equipped with an APS-C sensor. The 30D has a resolution of 8.2 megapixel, whereas the 77D provides 24 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 30D vs Canon 77D

The side-by-side display below illustrates the physical size and weight of the Canon 30D and the Canon 77D. 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. 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 30D – 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 77D is notably smaller (14 percent) than the Canon 30D. Moreover, the 77D is markedly lighter (31 percent) than the 30D. In this context, it is worth noting that neither the 30D nor the 77D are weather-sealed.

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 30D gets 750 shots out of its BP-511A battery, while the 77D can take 600 images on a single charge of its LP-E17 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 camera comparisons there.

The price is, of course, an important factor in any camera decision. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The 77D was launched at a markedly lower price (by 36 percent) than the 30D, 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.

Sensor comparison: Canon 30D vs Canon 77D

The size of the imaging sensor is a crucial determinant 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 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 77D is 2 percent smaller. 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 30D and Canon 77D sensor measures

Despite having a slightly smaller sensor, the 77D offers a higher resolution of 24 megapixel, compared with 8.2 MP of the 30D. 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 6.42μm for the 30D). However, it should be noted that the 77D is much more recent (by 10 years and 11 months) than the 30D, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently.

30D versus 77D MP

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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 77D offers substantially better image quality than the 30D (overall score 19 points higher). The advantage is based on 2.1 bits higher color depth, 2.5 EV in additional dynamic range, and 0.4 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 77D indeed provides for movie recording, while the 30D does not. The highest resolution format that the 77D can use is 1080/60p.

Feature comparison: Canon 30D vs Canon 77D

Apart from body and sensor, cameras can and do differ across a variety of features. The 30D and the 77D 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 30D, the Canon 77D, 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 30D has been discontinued (but it can be found pre-owned on eBay). As a replacement in the same line of cameras, the 30D was succeeded by the Canon 40D.

Review summary: Canon 30D vs Canon 77D

So what conclusions can be drawn? Is there a clear favorite between the Canon 30D and the Canon 77D? A synthesis of the relative strong points of each of the models is listed below.


Arguments in favor of the Canon EOS 30D:

  • Faster shutter: Has higher mechanical shutter speed (8000/sec vs 4000/sec) to freeze action.
  • Longer lasting: Can take more shots (750 versus 600) on a single battery charge.
  • More heavily discounted: Has been available for much longer (launched in February 2006).

Reasons to prefer the Canon EOS 77D:

  • More detail: Has more megapixels (24 vs 8.2MP), which boosts linear resolution by 71%.
  • Better image quality: Scores substantially higher (19 points) in the DXO overall evaluation.
  • Richer colors: Generates noticeably more natural colors (2.1 bits more color depth).
  • More dynamic range: Captures a broader range of light and dark details (2.5 EV of extra DR).
  • Better low-light sensitivity: Can shoot in dim conditions (0.4 stops ISO advantage).
  • Broader imaging potential: Can capture not only stills but also 1080/60p video.
  • 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).
  • 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.
  • Faster burst: Shoots at higher frequency (6 vs 5 flaps/sec) to capture the decisive moment.
  • More compact: Is smaller (131x100mm vs 144x106mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight (by 245g or 31 percent) and is thus easier to take along.
  • More affordable: Was introduced into a lower priced category (36 percent cheaper at launch).
  • More modern: Reflects 10 years and 11 months of technical progress since the 30D launch.

If the count of individual advantages (bullet points above) is taken as a guide, the 77D is the clear winner of the contest (15 : 3 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.

30D 03:15 77D

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 30D or the 77D 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. This is why hands-on reviews by experts are important.

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 comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
