Body comparison

The side-by-side display below illustrates the physical size and weight of the Olympus E-620 and the Canon 1D Mark IV. The two cameras are presented according to their relative size. Three consecutive views from the front, the top, and the rear side are shown. All width, height and depth dimensions are rounded to the nearest millimeter.

Size Olympus E-620 vs Canon 1D Mark IV
Compare E-620 versus 1D Mark IV top
Comparison E-620 or 1D Mark IV rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Canon 1D Mark IV is considerably larger (100 percent) than the Olympus E-620. Moreover, the 1D Mark IV is substantially heavier (136 percent) than the E-620. It is noteworthy in this context that the 1D Mark IV 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 IV).

Concerning battery life, the E-620 gets 500 shots out of its Olympus BLS-1 battery, while the 1D Mark IV can take 1500 images on a single charge of its Canon LP-E4 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. 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.

The price is, of course, an important factor in any camera decision. 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. 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. 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. 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 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 IV an APS-H sensor. The sensor area in the 1D Mark IV is 131 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 IV offers a 3:2 aspect.

Olympus E-620 and Canon 1D Mark IV sensor measures

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 pixel-units.

The resolution advantage of the Canon 1D Mark IV implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the 1D Mark IV for good quality output (200 dots per inch) amounts to 24.5 x 16.3 inches or 62.2 x 41.5 cm, for very good quality (250 dpi) 19.6 x 13.1 inches or 49.7 x 33.2 cm, and for excellent quality (300 dpi) 16.3 x 10.9 inches or 41.5 x 27.6 cm. The corresponding values for the Olympus E-620 are 20.2 x 15.1 inches or 51.2 x 38.4 cm for good quality, 16.1 x 12.1 inches or 41 x 30.7 cm for very good quality, and 13.4 x 10.1 inches or 34.1 x 25.6 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 IV are ISO 100 to ISO 12800, with the possibility to increase the ISO range to 50-102400.

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.

E-620 versus 1D Mark IV MP

For many cameras, data on sensor performance has been reported by DXO Mark. 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 IV offers substantially better image quality than the E-620 (overall score 19 points higher). The 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 table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. The E-620 and the 1D Mark IV 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 Olympus E-620 and Canon 1D Mark IV 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 IV 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 has an articulated LCD that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in snapping selfies. In contrast, the 1D Mark IV does not have a selfie-screen.

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

Studio photographers will appreciate that the Canon 1D Mark IV (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 IV have been discontinued, but can regularly be found used on ebay. The E-620 was replaced by the Olympus E-600, while the 1D Mark IV does not have a direct successor. Further information on the features and operation of the E-620 and 1D Mark IV can be found, respectively, in the Olympus E-620 Manual (free pdf) or the online Canon 1D Mark IV Manual.

  • Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/4000s) to freeze action.
  • Faster burst: Shoots at higher frequency (10 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 (1500 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 modern: Was introduced somewhat (7 months) more recently.

If the count of relative strengths (bullet points above) is taken as a measure, the 1D Mark IV is the clear winner of the contest (18 : 8 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 wildlife photographer will view the differences between cameras in a way that diverges from the perspective of a family photog, and a person interested in architecture has distinct needs from a sports shooter. Hence, the decision which camera is best and worth buying is often a very personal one.

E-620 08:18 1D Mark IV

How about other alternatives? Do the specifications of the Olympus E-620 and the Canon 1D Mark IV 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 says little about, for example, the shooting experience and imaging performance of the E-620 and the 1D Mark IV in practical situations. 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 where reviews by experts come in. The table below provides a synthesis of the camera assessments of some of the best known photo-gear 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.

The review scores listed above should be treated with care, though. The ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. A score, therefore, has to be seen in close connection to the price and market introduction time 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. Also, please note that some of the review sites have changed their methodology and reporting over time.
