Going beyond this snapshot of core features and characteristics, what are the differences between the Olympus E-620 and the Canon EOS-1D Mark II? 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 Olympus E-620 and the Canon 1D Mark II 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 1D Mark II is considerably larger (102 percent) than the Olympus E-620. Moreover, the 1D Mark II is substantially heavier (195 percent) than the E-620. It is noteworthy in this context that the 1D Mark II is splash and dust-proof, while the E-620 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. A larger imaging sensor will tend to go along with bigger and heavier lenses, although exceptions exist. You can compare the optics available for the two cameras in the Four Thirds Lens Catalog (E-620) and the Canon EF Lens Catalog (1D Mark II).

Concerning battery life, the E-620 gets 500 shots out of its Olympus BLS-1 battery, while the 1D Mark II can take 1200 images on a single charge of its Canon NP-E3 power pack. As can be seen in the images above, the 1D Mark II has a battery grip built in. This facilitates image-taking in portrait orientation and gives it additional battery power. In order to provide similar functionality for the E-620, Olympus provides the HLD-5 vertical grip as an optional accessory (see here on ebay).

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 E-620 was launched at a markedly lower price (by 84 percent) than the 1D 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.

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 Olympus E-620 features a Four Thirds sensor and the Canon 1D Mark II an APS-H sensor. The sensor area in the 1D Mark II is 144 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.0 and 1.3. The sensor in the E-620 has a native 4:3 aspect ratio, while the one in the 1D Mark II offers a 3:2 aspect.

Despite having a smaller sensor, the Olympus E-620 offers a higher resolution of 12.2 megapixels, compared with 8.2 MP of the Canon 1D Mark II. This megapixels advantage comes at the cost of a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 4.29μm versus 8.17μm for the 1D Mark II). However, it should be noted that the E-620 is much more recent (by 5 years) than the 1D Mark II, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently.

The resolution advantage of the Olympus E-620 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the E-620 for good quality output (200 dots per inch) amounts to 20.2 x 15.1 inches or 51.2 x 38.4 cm, for very good quality (250 dpi) 16.1 x 12.1 inches or 41 x 30.7 cm, and for excellent quality (300 dpi) 13.4 x 10.1 inches or 34.1 x 25.6 cm. The corresponding values for the Canon 1D Mark II are 17.5 x 11.7 inches or 44.5 x 29.7 cm for good quality, 14 x 9.3 inches or 35.6 x 23.7 cm for very good quality, and 11.7 x 7.8 inches or 29.7 x 19.8 cm for excellent quality prints.

The Olympus E-620 has a native sensitivity range from ISO 100 to ISO 3200. The corresponding ISO settings for the Canon EOS-1D Mark II are ISO 100 to ISO 1600, with the possibility to increase the ISO range to 50-3200.

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 consideration, the 1D Mark II offers substantially better image quality than the E-620 (overall score 11 points higher). The advantage is based on 1 bits higher color depth, 0.8 EV in additional dynamic range, and 0.9 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.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. The E-620 and the 1D 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 viewfinder in the 1D Mark II offers a wider field of view (100%) than the one in the E-620 (95%), so that a larger proportion of the captured image is visible in the finder. In addition, the viewfinder of the 1D Mark II has a higher magnification (0.55x vs 0.48x), 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 Olympus E-620 and Canon 1D Mark II along with similar information for a selection of comparators.

One difference between the cameras concerns the presence of an on-board flash. The E-620 has one, while the 1D Mark II does not. While the built-in flash of the E-620 is not very powerful, it can at times be useful as a fill-in light.

The E-620 writes its imaging data to Compact Flash or xD Picture cards, while the 1D Mark II uses Compact Flash or SD cards. Both cameras feature dual card slots, which can be very useful in case a memory card fails.

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 Olympus E-620 and Canon EOS-1D Mark II and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Studio photographers will appreciate that the Canon 1D Mark II (unlike the E-620) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Both the E-620 and the 1D Mark II have been discontinued, but can regularly be found used on ebay. The 1D Mark II was replaced by the Canon 1D Mark II N, while the E-620 was followed by the Olympus E-600. Further information on the features and operation of the E-620 and 1D Mark II can be found, respectively, in the Olympus E-620 Manual (free pdf) or the online Canon 1D Mark II Manual.

Review summary

So what is the bottom line? Which of the two cameras – the Olympus E-620 or the Canon 1D Mark II – 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 Olympus E-620:

• More detail: Offers more megapixels (12.2 vs 8.2MP) with a 20% higher linear resolution.
• Larger screen: Has a bigger rear LCD (2.7" vs 2.0") for image review and settings control.
• More flexible LCD: Has a swivel screen for odd-angle shots in portrait or landscape orientation.
• More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
• More compact: Is smaller (130x94mm vs 156x158mm) and thus needs less room in the bag.
• Less heavy: Is lighter (by 1014g or 66 percent) and hence easier to carry around.
• Sharper images: Has hand-shake reducing image stabilization built-in.
• Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
• Faster data transfer: Supports a more advanced USB protocol (2.0 vs 1.1).
• More affordable: Was introduced into a lower priced category (84 percent cheaper at launch).
• More modern: Reflects 5 years of technical progress since the 1D Mark II launch.

Arguments in favor of the Canon EOS-1D Mark II:

• Better image quality: Scores substantially higher (11 points) in the DXO overall evaluation.
• More dynamic range: Captures a broader range of light and dark details (0.8 EV of extra DR).
• Better low-light sensitivity: Can shoot in dim conditions (0.9 stops ISO advantage).
• 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 (0.55x vs 0.48x).
• Easier setting verification: Features a control panel on top to check shooting parameters.
• Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/4000s) to freeze action.
• Faster burst: Shoots at higher frequency (8.3 vs 4 flaps/sec) to capture the decisive moment.
• More portrait friendly: Features an integrated vertical grip for easier portrait shooting.
• Longer lasting: Gets more shots (1200 versus 500) out of a single battery charge.
• Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
• Better studio light control: Has a PC Sync socket to connect to professional strobe lights.
• More heavily discounted: Has been around for much longer (launched in January 2004).

If the count of individual advantages (bullet points above) is taken as a guide, the 1D Mark II emerges as the winner of the match-up (13 : 11 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 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 Olympus E-620 and the Canon 1D Mark II 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 E-620 or the 1D Mark II. 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.

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.
