Body comparison: Canon 1D Mark IV vs Olympus E-620
The side-by-side display below illustrates the physical size and weight of the Canon 1D Mark IV and the Olympus E-620. The two cameras are presented according to their relative size. Three successive views from the front, the top, and the rear are shown. All size 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 Olympus E-620 is considerably smaller (50 percent) than the Canon 1D Mark IV. Moreover, the E-620 is substantially lighter (58 percent) than the 1D Mark IV. It is worth mentioning in this context that the 1D Mark IV is splash and dust resistant, 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 Canon EF Lens Catalog (1D Mark IV) and the Four Thirds Lens Catalog (E-620).
Concerning battery life, the 1D Mark IV gets 1500 shots out of its LP-E4 battery, while the E-620 can take 500 images on a single charge of its BLS-1 power pack. As can be seen in the images above, the 1D Mark IV 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 adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives.

Any camera decision will obviously take relative prices into account. 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 E-620 was launched at a markedly lower price (by 86 percent) than the 1D Mark IV, 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: Canon 1D Mark IV vs Olympus E-620
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.
Of the two cameras under consideration, the Canon 1D Mark IV features an APS-H sensor and the Olympus E-620 a Four Thirds sensor. The sensor area in the E-620 is 57 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.3 and 2.0. The sensor in the 1D Mark IV has a native 3:2 aspect ratio, while the one in the E-620 offers a 4:3 aspect.
In terms of underlying technology, both cameras are build around CMOS sensors.
With 16MP, the 1D Mark IV offers a higher resolution than the E-620 (12.2MP), but the 1D Mark IV nevertheless has larger individual pixels (pixel pitch of 5.70μm versus 4.29μm for the E-620) due to its larger sensor. Moreover, the 1D Mark IV is a somewhat more recent model (by 7 months) than the E-620, and its sensor might have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixels.
The Canon EOS-1D Mark IV has a native sensitivity range from ISO 100 to ISO 12800, which can be extended to ISO 50-102400. The corresponding ISO settings for the Olympus E-620 are ISO 100 to ISO 3200 (no boost).
Consistent information on actual sensor performance is available from DXO Mark for many cameras. 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 1D Mark IV provides substantially higher image quality than the E-620, with an overall score that is 19 points higher. This advantage is based on 1.5 bits higher color depth, 1.7 EV in additional dynamic range, and 1.3 stops in additional low light sensitivity. The adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-cameras.

Many modern cameras are not only capable of taking still images, but can also record movies. The 1D Mark IV indeed provides movie recording capabilities, while the E-620 does not. The highest resolution format that the 1D Mark IV can use is 1080/30p.
Feature comparison: Canon 1D Mark IV vs Olympus E-620
Beyond body and sensor, cameras can and do differ across a range of features. The 1D Mark IV and the E-620 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 IV 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 IV has a higher magnification (0.58x 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 Canon 1D Mark IV and Olympus E-620 along with similar information for a selection of comparators.

One feature that is present on the 1D Mark IV, but is missing on the E-620 is a top-level LCD. While being, of course, smaller than the rear screen, the control panel conveys some of the essential shooting information and can be convenient for quick and easy settings verification.The E-620 has an articulated screen that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in taking selfies. In contrast, the 1D Mark IV does not have a selfie-screen.
The 1D Mark IV writes its imaging data to Compact Flash cards, while the E-620 uses Compact Flash or xD Picture cards. Both cameras feature dual card slots, which can be very useful in case a memory card fails.

Do the specifications of the Canon 1D Mark IV and the Olympus E-620 place the cameras among the top in their class? Find out in the latest Best DSLR Camera listing.In any case, while the specs-based evaluation of cameras can be instructive in revealing their potential as photographic tools, it remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the 1D Mark IV or the E-620. 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.

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. 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.
