Going beyond this snapshot of core features and characteristics, what are the differences between the Canon EOS 7D Mark II and the Canon EOS-D30? Which one should you buy? Read on to find out how these two cameras compare with respect to their body size, their imaging sensors, their shooting features, their input-output connections, and their reception by expert reviewers.

Body comparison

An illustration of the physical size and weight of the Canon 7D II and the Canon D30 is provided in the side-by-side display below. The two cameras are presented according to their relative size. 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 the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Canon D30 is somewhat smaller (4 percent) than the Canon 7D II. Moreover, the D30 is markedly lighter (18 percent) than the 7D Mark II. It is worth mentioning in this context that the 7D Mark II is splash and dust resistant, while the 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 compare the optics available in the Canon EF Lens Catalog.

Concerning battery life, the 7D Mark II gets 670 shots out of its Canon LP-E6N battery, while the D30 can take 540 images on a single charge of its Canon BP-511 power pack.

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. In case you want to display and compare another camera duo, you can use the CAM-parator app to select your camera combination among a large number of options.

Any camera decision will naturally be influenced heavily by the price. The retail prices at the time of the camera’s release place the model in the market relative to other models in the producer’s line-up and the competition. The 7D Mark II was launched at a markedly lower price (by 40 percent) than the 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.

Sensor comparison

The size of the sensor inside a digital camera is one of the key determinants 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. Moreover, a large sensor camera will give the photographer more control over depth-of-field in the image and, thus, the ability to better 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, but their sensors differ slightly in size. The sensor area in the D30 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.

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

The resolution advantage of the Canon 7D II implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the 7D Mark II for good quality output (200 dots per inch) amounts to 27.4 x 18.2 inches or 69.5 x 46.3 cm, for very good quality (250 dpi) 21.9 x 14.6 inches or 55.6 x 37.1 cm, and for excellent quality (300 dpi) 18.2 x 12.2 inches or 46.3 x 30.9 cm. The corresponding values for the Canon D30 are 10.8 x 7.2 inches or 27.4 x 18.3 cm for good quality, 8.6 x 5.8 inches or 21.9 x 14.6 cm for very good quality, and 7.2 x 4.8 inches or 18.3 x 12.2 cm for excellent quality prints.

The 7D Mark II has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.

The Canon EOS 7D Mark II has a native sensitivity range from ISO 100 to ISO 16000, which can be extended to ISO 100-51200. The corresponding ISO settings for the Canon EOS-D30 are ISO 100 to ISO 1600 (no boost).

Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors. Both cameras use a Bayer filter for capturing RGB colors on a square grid of photosensors. This arrangement is found in most digital cameras.

For many cameras, data on sensor performance has been reported by DXO Mark. 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"). 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 7D Mark II indeed provides movie recording capabilities, while the D30 does not. The highest resolution format that the 7D Mark II can use is 1080/60p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. The 7D Mark II and the D30 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 viewfinder in the 7D Mark II offers a wider field of view (100%) than the one in the D30 (95%), so that a larger proportion of the captured image is visible in the finder. In addition, the viewfinder of the 7D Mark II has a higher magnification (0.63x vs 0.54x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The following table reports on some other key feature differences and similarities of the Canon 7D II, the Canon D30, and comparable cameras.

The Canon 7D II has an intervalometer built-in. This enables the photographer to capture time lapse sequences, such as flower blooming, a sunset or moon rise, without purchasing an external camera trigger and related software.

The 7D Mark II writes its imaging data to Compact Flash or SDXC cards, while the D30 uses Compact Flash cards. The 7D Mark II features dual card slots, which can be very useful in case a memory card fails. In contrast, the D30 only has one slot.

Connectivity comparison

For some imaging applications, the extent to which a camera can communicate with its environment can be an important aspect in the camera decision process. The table below provides an overview of the connectivity of the Canon EOS 7D Mark II and Canon EOS-D30 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Both cameras feature a PC Sync terminal to control professional strobe lights, which will be appreciated by studio photographers.

Travel and landscape photographers will find it useful that the 7D Mark II has an internal geolocalization sensor and can record GPS coordinates in its EXIF data.

Both the 7D Mark II and the D30 have been discontinued, but can regularly be found used on ebay. The D30 was replaced by the Canon D60, while the 7D Mark II does not have a direct successor. Further information on the features and operation of the 7D Mark II and D30 can be found, respectively, in the Canon 7D II Manual (free pdf) or the online Canon D30 Manual.

Review summary

So what is the bottom line? Is the Canon 7D II better than the Canon D30 or vice versa? A synthesis of the relative strong points of each of the models is listed below.

Reasons to prefer the Canon EOS 7D Mark II:

• More detail: Offers more megapixels (20 vs 3.1MP) with a 153% higher linear resolution.
• Broader imaging potential: Can record not only still images but also 1080/60p movies.
• Better live-view autofocus: Features on-sensor phase-detection for more confident autofocus.
• More complete view: Has a viewfinder with a larger field of view (100% vs 95%).
• Larger viewfinder image: Features a viewfinder with a higher magnification (0.63x vs 0.54x).
• 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 (1/8000s vs 1/4000s) to freeze action.
• Faster burst: Shoots at higher frequency (10 vs 3 flaps/sec) to capture the decisive moment.
• Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
• Longer lasting: Can take more shots (670 versus 540) on a single battery charge.
• Better sealing: Is weather sealed to enable shooting in dusty or wet environments.
• Easier geotagging: Features an internal GPS sensor to log localization data.
• Faster data transfer: Supports a more advanced USB protocol (3.0 vs 1.0).
• Greater peace of mind: Features a second card slot as a backup in case of memory card failure.
• 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 D30 launch.

Arguments in favor of the Canon EOS-D30:

• Less heavy: Has a lower weight (by 160g or 18 percent) and is thus easier to take along.
• More heavily discounted: Has been around for much longer (launched in May 2000).

If the number of relative strengths (bullet points above) is taken as a guide, the 7D Mark II is the clear winner of the match-up (17 : 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. A professional wedding photographer will view the differences between cameras in a way that diverges from the perspective of a travel photog, and a person interested in cityscapes has distinct needs from a macro shooter. Hence, the decision which camera is best and worth buying is often a very personal one.

How about other alternatives? Do the specifications of the Canon 7D II and the Canon D30 place the cameras among the top in their class? Find out in the latest Best DSLR Camera listing whether the two cameras rank among the cream of the crop.

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 shooting experience and imaging performance when actually working with the 7D Mark II or the D30. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased.

Expert reviews

This is why expert reviews are important. The following table reports the overall ratings of the cameras as published by some of the major camera review sites (amateurphotographer [AP], cameralabs [CL], digitalcameraworld [DCW], dpreview [DPR], ephotozine [EPZ], photographyblog [PB]). As can be seen, the professional reviewers agree in many cases on the quality of different cameras, but sometimes their assessments diverge, reinforcing the earlier point that a camera decision is often a very personal choice.

Note: (+ +) highly recommended; (+) recommended; (o) reviewed; (..) not available.

The review scores listed above should be treated with care, though. The ratings are only valid when referring to cameras in the same category and of the same age. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, and comparisons of ratings among very different cameras or across long time periods have little meaning. Also, please note that some of the review sites have changed their methodology and reporting over time.
