Going beyond this snapshot of core features and characteristics, what are the differences between the Canon EOS 5D Mark II and the Canon EOS 7D? 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

The side-by-side display below illustrates the physical size and weight of the Canon 5D Mark II and the Canon 7D. The two cameras are presented according to their relative size. Three consecutive perspectives from the front, the top, and the back are available. 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 7D is notably smaller (5 percent) than the Canon 5D Mark II. However, the 7D is slightly heavier (1 percent) than the 5D Mark II. 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. A larger imaging sensor (as in the 5D Mark II) will tend to go along with bigger and heavier lenses, while more compact options are available for the smaller-sensor camera (7D). You can compare the optics available in the Canon EF Lens Catalog.

The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. If you would like to visualize and compare a different camera combination, you can navigate to the CAM-parator app and make your selection from a broad list of cameras there.

Any camera decision will obviously take relative prices into account. The manufacturer’s suggested retail prices give an idea on the placement of the camera in the maker’s lineup and the broader market. The 7D was launched at a markedly lower price (by 51 percent) than the 5D Mark II, which puts it into a different market segment. Normally, street prices remain initially close to the MSRP, but after a couple of months, the first discounts appear. 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 imaging sensor is a crucial determinant of image quality. A large sensor will tend to have larger individual pixels that provide better low-light sensitivity, wider dynamic range, and richer color-depth than smaller pixel-units 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.

Of the two cameras under consideration, the Canon 5D Mark II features a full frame sensor and the Canon 7D an APS-C sensor. The sensor area in the 7D is 62 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.0 and 1.6. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

With 21MP, the 5D Mark II offers a higher resolution than the 7D (17.9MP), but the 5D Mark II nevertheless has larger individual pixels (pixel pitch of 6.41μm versus 4.31μm for the 7D) due to its larger sensor. However, the 7D is a somewhat more recent model (by 11 months) than the 5D Mark II, and its sensor might have benefitted from technological advances during this time that enhance the light gathering capacity of its pixels.

The resolution advantage of the Canon 5D Mark II implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the 5D Mark II for good quality output (200 dots per inch) amounts to 28.1 x 18.7 inches or 71.3 x 47.5 cm, for very good quality (250 dpi) 22.5 x 15 inches or 57.1 x 38 cm, and for excellent quality (300 dpi) 18.7 x 12.5 inches or 47.5 x 31.7 cm. The corresponding values for the Canon 7D are 25.9 x 17.3 inches or 65.8 x 43.9 cm for good quality, 20.7 x 13.8 inches or 52.7 x 35.1 cm for very good quality, and 17.3 x 11.5 inches or 43.9 x 29.3 cm for excellent quality prints.

The Canon EOS 5D Mark II has a native sensitivity range from ISO 100 to ISO 6400, which can be extended to ISO 50-25600. The corresponding ISO settings for the Canon EOS 7D are ISO 100 to ISO 6400, with the possibility to increase the ISO range to 100-12800.

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.

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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"). Of the two cameras under review, the 5D Mark II provides substantially higher image quality than the 7D, with an overall score that is 13 points higher. This advantage is based on 1.7 bits higher color depth, 0.2 EV in additional dynamic range, and 1.1 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 cannot only take still pictures, but also record videos. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, and both provide the same movie specifications (1080/30p).

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. The 5D Mark II and the 7D 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 offers a wider field of view (100%) than the one in the 5D Mark II (98%), so that a larger proportion of the captured image is visible in the finder. On the other hand, the viewfinder of the 5D Mark II has a higher magnification (0.71x vs 0.63x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The adjacent table lists some of the other core features of the Canon 5D Mark II and Canon 7D along with similar information for a selection of comparators.

One difference between the cameras concerns the presence of an on-board flash. The 7D has one, while the 5D Mark II does not. While the built-in flash of the 7D is not very powerful, it can at times be useful as a fill-in light.

Concerning the storage of imaging data, both the 5D Mark II and the 7D write their files to Compact Flash cards.

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 5D Mark II and Canon EOS 7D 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.

Both the 5D Mark II and the 7D have been discontinued, but can regularly be found used on ebay. The 5D Mark II was replaced by the Canon 5D Mark III, while the 7D was followed by the Canon 7D Mark II. Further information on the features and operation of the 5D Mark II and 7D can be found, respectively, in the Canon 5D Mark II Manual (free pdf) or the online Canon 7D Manual.

Review summary

So what is the bottom line? Which of the two cameras – the Canon 5D Mark II or the Canon 7D – has the upper hand? Is one clearly better than the other? Below is a summary of the relative strengths of each of the two contestants.

Advantages of the Canon EOS 5D Mark II:

• More detail: Offers more megapixels (21 vs 17.9MP) with a 8% higher linear resolution.
• Better image quality: Scores substantially higher (13 points) in the DXO overall assessment.
• Richer colors: Generates images with noticeably better colors (1.7 bits more color depth).
• Better low-light sensitivity: Requires less light for good images (1.1 stops ISO advantage).
• Larger viewfinder image: Features a viewfinder with a higher magnification (0.71x vs 0.63x).
• More heavily discounted: Has been on the market for longer (launched in September 2008).

Arguments in favor of the Canon EOS 7D:

• More complete view: Has a viewfinder with a larger field of view (100% vs 98%).
• Faster burst: Shoots at higher frequency (8 vs 3.9 flaps/sec) to capture the decisive moment.
• Easier fill-in: Has a small integrated flash to brighten shadows of backlit subjects.
• More affordable: Was introduced into a lower priced category (51 percent cheaper at launch).
• More modern: Was introduced somewhat (11 months) more recently.

If the count of individual advantages (bullet points above) is taken as a guide, the 5D Mark II comes out slightly ahead of the 7D (6 : 5 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 when reflecting and deciding on a new camera. A professional sports photographer will view the differences between cameras in a way that diverges from the perspective of a street photog, and a person interested in family portraits has distinct needs from a landscape 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 5D Mark II and the Canon 7D 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 5D Mark II or the 7D. 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.

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 comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
