Going beyond this snapshot of core features and characteristics, what are the differences between the Canon EOS-1Ds Mark III and the Olympus Evolt E-330? 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 1Ds Mark III and the Olympus E-330. 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 measures 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-330 is considerably smaller (49 percent) than the Canon 1Ds Mark III. Moreover, the E-330 is substantially lighter (54 percent) than the 1Ds Mark III. It is worth mentioning in this context that the 1Ds Mark III is splash and dust resistant, while the E-330 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 (1Ds Mark III) and the Four Thirds Lens Catalog (E-330).

Concerning battery life, the 1Ds Mark III gets 1800 shots out of its Canon LP-E4 battery, while the E-330 can take 750 images on a single charge of its Olympus BLM-1 power pack. As can be seen in the images above, the 1Ds Mark III 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-330, there are third party battery grips available as optional accessories (see here on ebay).

Any camera decision will obviously take relative prices into account. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The E-330 was launched at a markedly lower price (by 88 percent) than the 1Ds Mark III, 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

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. 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 Canon 1Ds Mark III features a full frame sensor and the Olympus E-330 a Four Thirds sensor. The sensor area in the E-330 is 74 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.0 and 2.0. The sensor in the 1Ds Mark III has a native 3:2 aspect ratio, while the one in the E-330 offers a 4:3 aspect.

With 21MP, the 1Ds Mark III offers a higher resolution than the E-330 (7.4MP), but the 1Ds Mark III nevertheless has larger individual pixels (pixel pitch of 6.41μm versus 5.51μm for the E-330) due to its larger sensor. Moreover, the 1Ds Mark III is a somewhat more recent model (by 1 year and 6 months) than the E-330, and its sensor might have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixels.

The resolution advantage of the Canon 1Ds Mark III implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the 1Ds Mark III 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 Olympus E-330 are 15.7 x 11.8 inches or 39.8 x 29.9 cm for good quality, 12.5 x 9.4 inches or 31.9 x 23.9 cm for very good quality, and 10.5 x 7.8 inches or 26.6 x 19.9 cm for excellent quality prints.

The Canon EOS-1Ds Mark III has a native sensitivity range from ISO 100 to ISO 1600, which can be extended to ISO 50-3200. The corresponding ISO settings for the Olympus Evolt E-330 are ISO 100 to ISO 400, with the possibility to increase the ISO range to 100-1600.

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 assesses and scores the color depth ("DXO Portrait"), dynamic range ("DXO Landscape"), and low-light sensitivity ("DXO Sports") of camera sensors, and also publishes an overall camera score. 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

Apart from body and sensor, cameras can and do differ across a range of features. The 1Ds Mark III and the E-330 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 1Ds Mark III offers a wider field of view (100%) than the one in the E-330 (95%), so that a larger proportion of the captured image is visible in the finder. In addition, the viewfinder of the 1Ds Mark III has a higher magnification (0.76x vs 0.47x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The table below summarizes some of the other core capabilities of the Canon 1Ds Mark III and Olympus E-330 in connection with corresponding information for a sample of similar cameras.

One feature that is present on the 1Ds Mark III, but is missing on the E-330 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 1Ds Mark III writes its imaging data to Compact Flash or SDHC cards, while the E-330 uses Compact Flash or xD Picture 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 Canon EOS-1Ds Mark III and Olympus Evolt E-330 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Studio photographers will appreciate that the Canon 1Ds Mark III (unlike the E-330) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Both the 1Ds Mark III and the E-330 have been discontinued, but can regularly be found used on ebay. The 1Ds Mark III was replaced by the Canon 1DX, while the E-330 does not have a direct successor. Further information on the features and operation of the 1Ds Mark III and E-330 can be found, respectively, in the Canon 1Ds Mark III Manual (free pdf) or the online Olympus E-330 Manual.

Review summary

So what is the bottom line? Which of the two cameras – the Canon 1Ds Mark III or the Olympus E-330 – has the upper hand? Is one clearly better than the other? A synthesis of the relative strong points of each of the models is listed below.

Advantages of the Canon EOS-1Ds Mark III:

• More detail: Offers more megapixels (21 vs 7.4MP) with a 72% higher linear resolution.
• Better image quality: Features a larger and more technologically advanced imaging sensor.
• Richer colors: The sensor size advantage translates into images with better, more accurate colors.
• More dynamic range: Larger sensor captures a wider spectrum of light and dark details.
• Better low-light sensitivity: Larger sensor produces good images even in poorly lit environments.
• 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 (0.76x vs 0.47x).
• Easier setting verification: Features an LCD display on top to control shooting parameters.
• Larger screen: Has a bigger rear LCD (3.0" vs 2.5") for image review and settings control.
• Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/4000s) to freeze action.
• Faster burst: Shoots at higher frequency (5 vs 3 flaps/sec) to capture the decisive moment.
• More portrait friendly: Features an integrated vertical grip for easier portrait shooting.
• Longer lasting: Can take more shots (1800 versus 750) on a single battery charge.
• Better sealing: Is weather sealed to enable shooting in dusty or wet environments.
• Better studio light control: Has a PC Sync socket to connect to professional strobe lights.
• More modern: Is somewhat more recent (announced 1 year and 6 months after the E-330).

Reasons to prefer the Olympus Evolt E-330:

• More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
• More compact: Is smaller (140x87mm vs 150x160mm) and will fit more readily into a bag.
• Less heavy: Has a lower weight (by 748g or 54 percent) and is thus easier to take along.
• Easier fill-in: Has a small integrated flash to brighten shadows of backlit subjects.
• More affordable: Was introduced into a lower priced category (88 percent cheaper at launch).
• More heavily discounted: Has been on the market for longer (launched in January 2006).

If the count of relative strengths (bullet points above) is taken as a measure, the 1Ds Mark III is the clear winner of the match-up (16 : 6 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 Canon 1Ds Mark III and the Olympus E-330 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 1Ds Mark III or the E-330 perform in practice. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased.

Expert reviews

This is why expert reviews 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.

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.
