Going beyond this snapshot of core features and characteristics, what are the differences between the Olympus E-3 and the Olympus E-30? 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-3 and the Olympus E-30 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 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-30 is notably smaller (7 percent) than the Olympus E-3. Moreover, the E-30 is markedly lighter (20 percent) than the E-3. It is worth mentioning in this context that the E-3 is splash and dust resistant, while the E-30 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. In this particular case, both cameras feature the same lens mount, so that they can use the same lenses. You can compare the optics available in the Four Thirds Lens Catalog.

The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones.

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-30 was launched at a somewhat lower price (by 24 percent) than the E-3, which makes it more attractive for photographers on a tight budget. 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 sensor inside a digital camera is one of the key determinants 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 more expensive and lead to bigger and heavier cameras and lenses.

Both cameras under consideration feature a Four Thirds sensor and have a format factor (sometimes also referred to as "crop factor") of 2.0. Within the spectrum of camera sensors, this places the review cameras among the medium-sized sensor cameras that aim to strike a balance between image quality and portability. Both cameras feature a native aspect ratio (sensor width to sensor height) of 4:3.

Technology-wise, the E-30 uses a more advanced image processing engine (TruePic III+) than the E-3 (TruePic III), with benefits for noise reduction, color accuracy, and processing speed.

While the two cameras under review share the same sensor size, the E-30 offers a higher resolution of 12.2 megapixels, compared with 10 MP of the E-3. This megapixels advantage translates into a 11 percent gain in linear resolution. On the other hand, these sensor specs imply that the E-30 has a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 4.29μm versus 4.74μm for the E-3). However, it should be noted that the E-30 is a somewhat more recent model (by 1 year) than the E-3, and its sensor might have benefitted from technological advances during this time that at least partly compensate for the smaller pixel size.

The resolution advantage of the Olympus E-30 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the E-30 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 Olympus E-3 are 18.2 x 13.7 inches or 46.3 x 34.7 cm for good quality, 14.6 x 10.9 inches or 37.1 x 27.8 cm for very good quality, and 12.2 x 9.1 inches or 30.9 x 23.2 cm for excellent quality prints.

The Olympus E-3 has a native sensitivity range from ISO 100 to ISO 3200. The Olympus E-30 offers exactly the same ISO settings.

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 is based on lab testing and assigns an overall score to each camera sensor, as well as ratings for dynamic range ("DXO Landscape"), color depth ("DXO Portrait"), and low-light sensitivity ("DXO Sports"). The Overall DXO ratings for the two cameras under consideration are close, suggesting that they provide similar imaging performance. 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-3 and the E-30 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 E-3 offers a wider field of view (100%) than the one in the E-30 (98%), so that a larger proportion of the captured image is visible in the finder. In addition, the viewfinder of the E-3 has a higher magnification (0.58x vs 0.51x), 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 Olympus E-3 and Olympus E-30 in connection with corresponding information for a sample of similar cameras.

Concerning the storage of imaging data, both the E-3 and the E-30 write their files to 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 Olympus E-3 and Olympus E-30 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Studio photographers will appreciate that the Olympus E-3 (unlike the E-30) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Both the E-3 and the E-30 have been discontinued, but can regularly be found used on ebay. The E-3 was replaced by the Olympus E-5, while the E-30 does not have a direct successor. Further information on the features and operation of the E-3 and E-30 can be found, respectively, in the Olympus E-3 Manual (free pdf) or the online Olympus E-30 Manual.

Review summary

So what is the bottom line? Is there a clear favorite between the Olympus E-3 and the Olympus E-30? Which camera is better? The listing below highlights the relative strengths of the two models.

Reasons to prefer the Olympus E-3:

• More complete view: Has a viewfinder with a larger field of view (100% vs 98%).
• Larger viewfinder image: Features a viewfinder with a higher magnification (0.58x vs 0.51x).
• 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 heavily discounted: Has been on the market for longer (launched in October 2007).

Advantages of the Olympus E-30:

• More detail: Has more megapixels (12.2 vs 10MP), which boosts linear resolution by 11%.
• Better jpgs: Has a more modern image processing engine (TruePic III+ vs TruePic III).
• Larger screen: Has a bigger rear LCD (2.7" vs 2.5") for image review and settings control.
• Less heavy: Has a lower weight (by 175g or 20 percent) and is thus easier to take along.
• More affordable: Was released into a lower priced segment (24 percent cheaper at launch).
• More modern: Was introduced somewhat (1 year) more recently.

If the number of relative strengths (bullet points above) is taken as a guide, the E-30 comes out slightly ahead of the E-3 (6 : 5 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 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 Olympus E-3 and the Olympus E-30 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-3 or the E-30. 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 hands-on reviews by experts are important. The adjacent summary-table relays the overall verdicts of several of the most popular 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.

Note: (+ +) highly recommended; (+) recommended; (o) reviewed; (..) not available.

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. Hence, a score should always be seen in the context of the camera's market launch date and its price, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
