Olympus E-400 vs Sony A900
The Olympus E-400 and the Sony Alpha A900 are two digital cameras that were announced, respectively, in September 2006 and September 2008. Both are DSLR (Digital Single Lens Reflex) cameras that are based on a Four Thirds (E-400) and a full frame (A900) sensor. The Olympus has a resolution of 10 megapixels, whereas the Sony provides 24.4 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 Sony Alpha A900? 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 Olympus E-400 and the Sony A900. 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 Sony A900 is considerably larger (54 percent) than the Olympus E-400. Moreover, the A900 is substantially heavier (106 percent) than the E-400. It is noteworthy in this context that the A900 is splash and dust-proof, while the E-400 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. Hence, you might want to study and compare the specifications of available lenses in order to get the full picture of the size and weight of the two camera systems.
Concerning battery life, the E-400 gets 500 shots out of its Olympus BLS-1 battery, while the A900 can take 880 images on a single charge of its Sony NP-FM500H power pack.
The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. 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-400 was launched at a markedly lower price (by 77 percent) than the A900, 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. 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 Olympus E-400 features a Four Thirds sensor and the Sony A900 a full frame sensor. The sensor area in the A900 is 283 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.0 and 1.0. The sensor in the E-400 has a native 4:3 aspect ratio, while the one in the A900 offers a 3:2 aspect.
With 24.4MP, the A900 offers a higher resolution than the E-400 (10MP), but the A900 nevertheless has larger individual pixels (pixel pitch of 5.94μm versus 4.74μm for the E-400) due to its larger sensor. Moreover, the A900 is a somewhat more recent model (by 1 year and 11 months) than the E-400, and its sensor might have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixel-units.
The resolution advantage of the Sony A900 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the A900 for good quality output (200 dots per inch) amounts to 30.2 x 20.2 inches or 76.8 x 51.2 cm, for very good quality (250 dpi) 24.2 x 16.1 inches or 61.4 x 41 cm, and for excellent quality (300 dpi) 20.2 x 13.4 inches or 51.2 x 34.1 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 Sony Alpha A900 are ISO 200 to ISO 3200, with the possibility to increase the ISO range to 100-6400.
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.
Consistent information on actual sensor performance is available from DXO Mark for many cameras.

Feature comparison
Apart from body and sensor, cameras can and do differ across a variety of features. The E-400 and the A900 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 A900 offers a wider field of view (100%) than the one in the E-400 (95%), so that a larger proportion of the captured image is visible in the finder. In addition, the viewfinder of the A900 has a higher magnification (0.74x vs 0.46x), 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 Olympus E-400, the Sony A900, and comparable cameras.

One difference between the cameras concerns the presence of an on-board flash. The E-400 has one, while the A900 does not. While the built-in flash of the E-400 is not very powerful, it can at times be useful as a fill-in light.
The E-400 writes its imaging data to Compact Flash or xD Picture cards, while the A900 uses Compact Flash or Memory Stick PRO Duo 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-400 and Sony Alpha A900 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Studio photographers will appreciate that the Sony A900 (unlike the E-400) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.
Both the E-400 and the A900 have been discontinued, but can regularly be found used on ebay. The E-400 was replaced by the Olympus E-410, while the A900 was followed by the Sony A99. Further information on the features and operation of the E-400 and A900 can be found, respectively, in the Olympus E-400 Manual (free pdf) or the online Sony A900 Manual.
Review summary
So what is the bottom line? Is the Olympus E-400 better than the Sony A900 or vice versa? Below is a summary of the relative strengths of each of the two contestants.
Arguments in favor of the Olympus E-400:
- More compact: Is smaller (130x91mm vs 156x117mm) and thus needs less room in the bag.
- Less heavy: Is lighter (by 460g or 51 percent) and hence easier to carry around.
- Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
- More affordable: Was introduced into a lower priced category (77 percent cheaper at launch).
- More heavily discounted: Has been on the market for longer (launched in September 2006).
Reasons to prefer the Sony Alpha A900:
- More detail: Has more megapixels (24.4 vs 10MP), which boosts linear resolution by 59%.
- Better image quality: Is equipped with a larger and more technologically advanced 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 (0.74x vs 0.46x).
- Easier setting verification: Features a control panel on top to check shooting parameters.
- Larger screen: Has a bigger rear LCD (3.0" vs 2.5") for image review and settings control.
- More detailed LCD: Has a higher resolution rear screen (922k vs 215k dots).
- 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.
- Longer lasting: Gets more shots (880 versus 500) out of a single battery charge.
- Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
- Sharper images: Has stabilization technology built-in to reduce the impact of hand-shake.
- Better studio light control: Has a PC Sync socket to connect to professional strobe lights.
- More modern: Was introduced somewhat (1 year and 11 months) more recently.
If the number of relative strengths (bullet points above) is taken as a guide, the A900 is the clear winner of the contest (17 : 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 wildlife photographer will view the differences between cameras in a way that diverges from the perspective of a family photog, and a person interested in architecture has distinct needs from a sports 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 Sony A900 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 E-400 or the A900 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 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], 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. 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. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
