Going beyond this snapshot of core features and characteristics, what are the differences between the Canon EOS 30D and the Olympus E-600? 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 30D and the Olympus E-600 is provided in the side-by-side display below. 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.

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Olympus E-600 is notably smaller (20 percent) than the Canon 30D. Moreover, the E-600 is markedly lighter (32 percent) than the 30D. In this context, it is worth noting that neither the 30D nor the E-600 are weather-sealed.

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 (30D) and the Four Thirds Lens Catalog (E-600).

Concerning battery life, the 30D gets 750 shots out of its Canon BP-511A battery, while the E-600 can take 500 images on a single charge of its Olympus BLS-1 power pack.

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. 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 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-600 was launched at a markedly lower price (by 68 percent) than the 30D, 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. 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 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. 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 30D features an APS-C sensor and the Olympus E-600 a Four Thirds sensor. The sensor area in the E-600 is 33 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.6 and 2.0. The sensor in the 30D has a native 3:2 aspect ratio, while the one in the E-600 offers a 4:3 aspect.

Despite having a smaller sensor, the E-600 offers a higher resolution of 12.2 megapixels, compared with 8.2 MP of the 30D. 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 6.42μm for the 30D). However, it should be noted that the E-600 is much more recent (by 3 years and 6 months) than the 30D, 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-600 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the E-600 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 30D 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 Canon EOS 30D has a native sensitivity range from ISO 100 to ISO 1600, which can be extended to ISO 100-3200. The corresponding ISO settings for the Olympus E-600 are ISO 100 to ISO 3200 (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 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 30D has a notably higher overall DXO score than the E-600 (overall score 4 points higher), which gives it an advantage in terms of imaging quality. 0.5 EV in additional dynamic range, and 0.4 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.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. The 30D and the E-600 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 viewfinders of both cameras offer the same field of view (95%), but the viewfinder of the 30D has a higher magnification than the one of the E-600 (0.56x vs 0.48x), 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 30D, the Olympus E-600, and comparable cameras.

One feature that is present on the 30D, but is missing on the E-600 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 30D writes its imaging data to Compact Flash cards, while the E-600 uses Compact Flash or xD Picture cards. The E-600 features dual card slots, which can be very useful in case a memory card fails. In contrast, the 30D 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 30D and Olympus E-600 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Studio photographers will appreciate that the Canon 30D (unlike the E-600) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Both the 30D and the E-600 have been discontinued, but can regularly be found used on ebay. The 30D was replaced by the Canon 40D, while the E-600 does not have a direct successor. Further information on the features and operation of the 30D and E-600 can be found, respectively, in the Canon 30D Manual (free pdf) or the online Olympus E-600 Manual.

Review summary

So how do things add up? Is the Canon 30D better than the Olympus E-600 or vice versa? The listing below highlights the relative strengths of the two models.

Reasons to prefer the Canon EOS 30D:

• Better image quality: Scores markedly higher (4 points) in the DXO overall assessment.
• Better low-light sensitivity: Requires less light for good images (0.4 stops ISO advantage).
• Larger viewfinder image: Features a viewfinder with a higher magnification (0.56x vs 0.48x).
• Easier setting verification: Features an LCD display on top to control shooting parameters.
• Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/4000s) to freeze action.
• Faster burst: Shoots at higher frequency (5 vs 4 flaps/sec) to capture the decisive moment.
• Longer lasting: Can take more shots (750 versus 500) on a single battery charge.
• Better studio light control: Has a PC Sync socket to connect to professional strobe lights.
• More heavily discounted: Has been available for much longer (launched in February 2006).

Arguments in favor of the Olympus E-600:

• More detail: Has more megapixels (12.2 vs 8.2MP), which boosts linear resolution by 20%.
• Larger screen: Has a bigger rear LCD (2.7" vs 2.5") 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 144x106mm) and will fit more readily into a bag.
• Less heavy: Has a lower weight (by 250g or 32 percent) and is thus easier to take along.
• Sharper images: Has stabilization technology built-in to reduce the impact of hand-shake.
• 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 (68 percent cheaper at launch).
• More modern: Reflects 3 years and 6 months of technical progress since the 30D launch.

If the count of relative strengths (bullet points above) is taken as a measure, the E-600 comes out slightly ahead of the 30D (10 : 9 points). However, the relative importance of the various individual camera aspects will vary according to personal preferences and needs, so that you might like to apply corresponding weights to the particular features before making a decision on a new camera. 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 30D and the Olympus E-600 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 specs-based evaluation of cameras can be instructive in revealing their potential as photographic tools, it remains incomplete and does no justice, for example, to the way the 30D or the E-600 perform in practice. At times, user reviews, such as those published at amazon, address these issues in a useful manner, but such feedback is on many occasions incomplete, inconsistent, and unreliable.

Expert reviews

This is why hands-on reviews by experts are important. 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.

Care should be taken when interpreting the review scores above, though. The ratings are only valid when referring to cameras in the same category and of the same age. 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, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
