Olympus E-330 vs E-620
The Olympus Evolt E-330 and the Olympus E-620 are two digital cameras that were announced, respectively, in January 2006 and February 2009. Both are DSLR (Digital Single Lens Reflex) cameras that are equipped with a Four Thirds sensor. The E-330 has a resolution of 7.4 megapixels, whereas the E-620 provides 12.2 MP.
Below is an overview of the main specs of the two cameras as a starting point for the comparison.
Going beyond this snapshot of core features and characteristics, what are the differences between the Olympus Evolt E-330 and the Olympus E-620? 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.
The physical size and weight of the Olympus E-330 and the Olympus E-620 are illustrated 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 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-330 and the Olympus E-620 are of equal size. However, the E-620 is markedly lighter (18 percent) than the E-330. In this context, it is worth noting that neither the E-330 nor the E-620 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. 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 adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives. In case you want to display and compare another camera duo, you can use the CAM-parator app to select your camera combination among a large number of options.

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-620 was launched at a markedly lower price (by 30 percent) than the E-330, 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.
The size of the sensor inside a digital camera is one of the key determinants 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. 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.
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-620 uses a more advanced image processing engine (TruePic III+) than the E-330 (TruePic), with benefits for noise reduction, color accuracy, and processing speed.
While the two cameras under review share the same sensor size, the E-620 offers a higher resolution of 12.2 megapixels, compared with 7.4 MP of the E-330. This megapixels advantage translates into a 29 percent gain in linear resolution. On the other hand, these sensor specs imply that the E-620 has a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 4.29μm versus 5.51μm for the E-330). However, it should be noted that the E-620 is much more recent (by 3 years) than the E-330, and its sensor will have benefitted from technological advances during this time that compensate for the smaller pixel size.
The resolution advantage of the Olympus E-620 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the E-620 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-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 Olympus Evolt E-330 has a native sensitivity range from ISO 100 to ISO 400, which can be extended to ISO 100-1600. The corresponding ISO settings for the Olympus E-620 are ISO 100 to ISO 3200 (no boost).
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 following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.

Beyond body and sensor, cameras can and do differ across a range of features. The E-330 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 viewfinders of both cameras offer the same field of view (95%), but the viewfinder of the E-620 has a higher magnification than the one of the E-330 (0.48x vs 0.47x), 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-330 and Olympus E-620 along with similar information for a selection of comparators.

One feature that differentiates the E-620 and the E-330 is in-body image stabilization (IBIS). The E-620 reduces the risk of handshake-induced blur with all attached lenses, while the E-330 offers no blur reduction with lenses that themselves do not provide optical image stabilization.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 E-330 does not have a selfie-screen.
Concerning the storage of imaging data, both the E-330 and the E-620 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.
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 Evolt E-330 and Olympus E-620 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Both the E-330 and the E-620 have been discontinued, but can regularly be found used on eBay. The E-620 was replaced by the Olympus E-600, while the E-330 does not have a direct successor. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Olympus website.
So what conclusions can be drawn? Is the Olympus E-330 better than the Olympus E-620 or vice versa? A synthesis of the relative strong points of each of the models is listed below.
Advantages of the Olympus Evolt E-330:
- Longer lasting: Can take more shots (750 versus 500) on a single battery charge.
- More heavily discounted: Has been available for much longer (launched in January 2006).
Arguments in favor of the Olympus E-620:
- More detail: Has more megapixels (12.2 vs 7.4MP), which boosts linear resolution by 29%.
- Better jpgs: Has a more modern image processing engine (TruePic III+ vs TruePic).
- Larger viewfinder image: Features a viewfinder with a higher magnification (0.48x vs 0.47x).
- 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.
- Faster burst: Shoots at higher frequency (4 vs 3 flaps/sec) to capture the decisive moment.
- Less heavy: Has a lower weight (by 116g or 18 percent) and is thus easier to take along.
- Sharper images: Has stabilization technology built-in to reduce the impact of hand-shake.
- More affordable: Was introduced into a lower priced category (30 percent cheaper at launch).
- More modern: Reflects 3 years of technical progress since the E-330 launch.
If the count of relative strengths (bullet points above) is taken as a measure, the E-620 is the clear winner of the contest (11 : 2 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 Olympus E-330 and the Olympus E-620 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 the spec-sheets of cameras can offer a general idea of their imaging potential, it remains incomplete and does no justice, for example, to the way the E-330 or the E-620 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.
This is why expert reviews are important. The adjacent summary-table relays the overall verdicts of several of the most popular camera review sites (amateurphotographer [AP], cameralabs [CL], 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 above review scores should be interpreted with care, though. The assessments were made in relation to similar cameras of the same technological generation. 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.
