Olympus E-400 vs E-620
The Olympus E-400 and the Olympus E-620 are two digital cameras that were announced, respectively, in September 2006 and February 2009. Both are DSLR (Digital Single Lens Reflex) cameras that are equipped with a Four Thirds sensor. The E-400 has a resolution of 10 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 E-400 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.
An illustration of the physical size and weight of the Olympus E-400 and the Olympus E-620 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 size 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-620 is somewhat larger (3 percent) than the Olympus E-400. Moreover, the E-620 is markedly heavier (20 percent) than the E-400. In this context, it is worth noting that neither the E-400 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 following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. 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.

Any camera decision will obviously take relative prices into account. 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 two cameras under review were launched at the same price and fall into the same 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. 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. Furthermore, a large sensor camera will give the photographer more possibilities to use shallow depth-of-field in order to isolate a subject from the background. On the downside, larger sensors are more costly to manufacture and tend to 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-620 uses a more advanced image processing engine (TruePic III+) than the E-400 (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 10 MP of the E-400. This megapixels advantage translates into a 11 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 4.74μm for the E-400). However, it should be noted that the E-620 is much more recent (by 2 years and 5 months) than the E-400, 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-400 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-400 has a native sensitivity range from ISO 100 to ISO 1600. The corresponding ISO settings for the Olympus E-620 are ISO 100 to ISO 3200 (no boost).
Consistent information on actual sensor performance is available from DXO Mark for many cameras. 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 table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

Apart from body and sensor, cameras can and do differ across a range of features. The E-400 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-400 (0.48x vs 0.46x), 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-400 and Olympus E-620 in connection with corresponding information for a sample of similar cameras.
One feature that differentiates the E-620 and the E-400 is in-body image stabilization (IBIS). The E-620 reduces the risk of handshake-induced blur with all attached lenses, while the E-400 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-400 does not have a selfie-screen.
Concerning the storage of imaging data, both the E-400 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 E-400 and Olympus E-620 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Both the E-400 and the E-620 have been discontinued, but can regularly be found used on eBay. The E-400 was replaced by the Olympus E-410, while the E-620 was followed by the Olympus E-600. 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 how do things add up? Is the Olympus E-400 better than the Olympus E-620 or vice versa? A synthesis of the relative strong points of each of the models is listed below.
Reasons to prefer the Olympus E-400:
- Less heavy: Is lighter (by 86g or 17 percent) and hence easier to carry around.
- More heavily discounted: Has been available for much longer (launched in September 2006).
Arguments in favor of the Olympus E-620:
- 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).
- Larger viewfinder image: Features a viewfinder with a higher magnification (0.48x vs 0.46x).
- 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.
- Sharper images: Has stabilization technology built-in to reduce the impact of hand-shake.
- More modern: Reflects 2 years and 5 months of technical progress since the E-400 launch.
If the number of relative strengths (bullet points above) is taken as a guide, the E-620 is the clear winner of the contest (9 : 2 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 Olympus E-400 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 specs-based evaluation of cameras can be instructive in revealing their potential as photographic tools, it says little about, for example, the shooting experience and imaging performance of the E-400 and the E-620 in practical situations. 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 hands-on reviews by experts are important. The adjacent summary-table relays the overall verdicts of several of the most popular camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, and photographyblog). 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 are only valid when referring to cameras in the same category and of the same age. Thus, a score needs to be put into the context of the launch date and the launch price 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. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
