Canon D30 versus Canon 7D II

The Canon EOS-D30 and the Canon EOS 7D Mark II are two digital cameras that were announced, respectively, in May 2000 and September 2014. Both are DSLR (Digital Single Lens Reflex) cameras that are equipped with an APS-C sensor. The Canon D30 has a resolution of 3.1 megapixel, whereas the 7D Mark II provides 20 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 D30 vs Canon 7D II

The physical size and weight of the Canon D30 and the Canon 7D II 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 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 Canon D30 – 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 7D II is somewhat larger (4 percent) than the Canon D30. Moreover, the 7D Mark II is markedly heavier (21 percent) than the Canon D30. It is noteworthy in this context that the 7D Mark II is splash and dust-proof, while the Canon D30 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 Canon D30 gets 540 shots out of its BP-511 battery, while the 7D Mark II can take 670 images on a single charge of its LP-E6N 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 7D Mark II was launched at a markedly lower price (by 40 percent) than the Canon D30, 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 D30 vs Canon 7D II

The imaging sensor is at the core of digital cameras and its size is one of the main determining factors 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 7D Mark II 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.

Sensor size

With 20MP, the 7D Mark II offers a higher resolution than the Canon D30 (3.1MP), but the 7D Mark II has smaller individual pixels (pixel pitch of 4.10μm versus 10.29μm for the Canon D30). Yet, the 7D Mark II is a much more recent model (by 14 years and 4 months) than the Canon D30, and its sensor will have benefitted from technological advances during this time that enhance the light gathering capacity of its pixel-units.

Many modern cameras cannot only take still pictures, but also record videos. The 7D Mark II indeed provides for movie recording, while the Canon D30 does not. The highest resolution format that the 7D Mark II can use is 1080/60p.

Feature comparison: Canon D30 vs Canon 7D II

Beyond body and sensor, cameras can and do differ across a range of features. The Canon D30 and the 7D Mark II 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 D30, the Canon 7D II, and comparable cameras. The full specs-sheets can be found in the camera manual or, for example, in the dpreview camera hub.

The 7D Mark II is a current model that online retailers, such as amazon, will have in stock. In contrast, the Canon D30 has been discontinued (but it can be found pre-owned on eBay). As a replacement in the same line of cameras, the Canon D30 was succeeded by the Canon D60.

Review summary: Canon D30 vs Canon 7D II

So what conclusions can be drawn? Is there a clear favorite between the Canon D30 and the Canon 7D II? Below is a summary of the relative strengths of each of the two contestants.


Reasons to prefer the Canon EOS-D30:

  • Less heavy: Is lighter (by 160g or 18 percent) and hence easier to carry around.
  • More heavily discounted: Has been available for much longer (launched in May 2000).

Arguments in favor of the Canon EOS 7D Mark II:

  • More detail: Has more megapixels (20 vs 3.1MP), which boosts linear resolution by 153%.
  • Broader imaging potential: Can capture not only stills but also 1080/60p video.
  • Larger screen: Has a bigger rear LCD (3.0" vs 1.8") for image review and settings control.
  • More detailed LCD: Has a higher resolution rear screen (1040k vs 114k dots).
  • Faster shutter: Has higher mechanical shutter speed (8000/sec vs 4000/sec) to freeze action.
  • Faster burst: Shoots at higher frequency (10 vs 3 flaps/sec) to capture the decisive moment.
  • Longer lasting: Gets more shots (670 versus 540) out of a single battery charge.
  • Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
  • More affordable: Was introduced into a lower priced category (40 percent cheaper at launch).
  • More modern: Reflects 14 years and 4 months of technical progress since the Canon D30 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 (10 : 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 before making a camera decision.

Canon D30 02:10 7D Mark II

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 Canon D30 or the 7D Mark II 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 why hands-on reviews by experts are important. The following table reports the overall rankings of the cameras as published by some of the major camera review sites. You can find the full text of the reviews, respectively, at 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 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.
