Olympus E-400 vs E-P1
The Olympus E-400 and the Olympus PEN E-P1 are two digital cameras that were officially introduced, respectively, in September 2006 and June 2009. The E-400 is a DSLR, while the E-P1 is a mirrorless interchangeable lens camera. Both cameras are equipped with a Four Thirds sensor. The E-400 has a resolution of 10 megapixels, whereas the E-P1 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 PEN E-P1? 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 side-by-side display below illustrates the physical size and weight of the Olympus E-400 and the Olympus E-P1. 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.
The E-P1 can be obtained in three different colors (black, silver, white), while the E-400 is only available in black.
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Olympus E-P1 is notably smaller (28 percent) than the Olympus E-400. Moreover, the E-P1 is markedly lighter (18 percent) than the E-400. In this context, it is worth noting that neither the E-400 nor the E-P1 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. Both cameras have similarly sized sensors, but DSLRs have a larger flange-to-focal plane distance than mirrorless cameras, which imposes contraints on the optical engineering process and generally leads to bigger and heavier lenses. You can compare the optics available for the two cameras in the Four Thirds Lens Catalog (E-400) and the Micro Four Thirds Lens Catalog (E-P1). Mirrorless cameras, such as the E-P1, have moreover the advantage that they can use many lenses from other systems via adapters, as they have a relatively short flange to focal plane distance.

The price is, of course, an important factor in any camera decision. 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 somewhat lower price (by 13 percent) than the E-P1, 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.
The imaging sensor is at the core of digital cameras and its size is one of the main determining factors of image quality. A large sensor will tend to have larger individual pixels that provide better low-light sensitivity, wider dynamic range, and richer color-depth than smaller pixel-units 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 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-P1 uses a more advanced image processing engine (TruePic V) 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-P1 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-P1 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-P1 is much more recent (by 2 years and 9 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-P1 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the E-P1 for good quality output (200 dots per inch) amounts to 20.2 x 15.1 inch or 51.2 x 38.4 cm, for very good quality (250 dpi) 16.1 x 12.1 inch or 41 x 30.7 cm, and for excellent quality (300 dpi) 13.4 x 10.1 inch or 34.1 x 25.6 cm. The corresponding values for the Olympus E-400 are 18.2 x 13.7 inch or 46.3 x 34.7 cm for good quality, 14.6 x 10.9 inch or 37.1 x 27.8 cm for very good quality, and 12.2 x 9.1 inch 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 PEN E-P1 are ISO 100 to ISO 6400 (no boost).
For many cameras, data on sensor performance has been reported by DXO Mark. This service determines an overall sensor rating, as well as sub-scores for low-light sensitivity ("DXO Sports"), dynamic range ("DXO Landscape"), and color depth ("DXO Portrait"). The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

Many modern cameras cannot only take still pictures, but also record videos. The E-P1 indeed provides for movie recording, while the E-400 does not. The highest resolution format that the E-P1 can use is 720/30p.
Apart from body and sensor, cameras can and do differ across a range of features. For example, the E-400 has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the E-P1 relies on live view and the rear LCD for framing. The adjacent table lists some of the other core features of the Olympus E-400 and Olympus E-P1 along with similar information for a selection of comparators.

One difference between the cameras concerns the presence of an on-board flash. The E-400 has one, while the E-P1 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 E-P1 uses SDHC cards. The E-400 features dual card slots, which can be very useful in case a memory card fails. In contrast, the E-P1 only has one slot.
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 PEN E-P1 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Both the E-400 and the E-P1 have been discontinued, but can regularly be found used on eBay. The E-400 was replaced by the Olympus E-410, while the E-P1 was followed by the Olympus E-P2. 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 there a clear favorite between the Olympus E-400 and the Olympus E-P1? Which camera is better? A synthesis of the relative strong points of each of the models is listed below.
Advantages of the Olympus E-400:
- Easier framing: Has an optical viewfinder for image composition and settings control.
- Longer lasting: Can take more shots (500 versus 300) on a single battery charge.
- Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
- Greater peace of mind: Features a second card slot as a backup in case of memory card failure.
- More affordable: Was introduced into a lower priced segment (13 percent cheaper at launch).
- More heavily discounted: Has been available for much longer (launched in September 2006).
Arguments in favor of the Olympus PEN E-P1:
- 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 V vs TruePic).
- Broader imaging potential: Can capture not only stills but also 720/30p video.
- Larger screen: Has a bigger rear LCD (3.0" vs 2.5") for image review and settings control.
- More compact: Is smaller (121x70mm vs 130x91mm) and will fit more readily into a bag.
- Less heavy: Has a lower weight (by 80g 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 legacy lens friendly: Can use many non-native lenses via adapters.
- More modern: Reflects 2 years and 9 months of technical progress since the E-400 launch.
If the count of relative strengths (bullet points above) is taken as a measure, the E-P1 emerges as the winner of the match-up (9 : 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 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 Olympus E-P1 place the cameras among the top in their class? Find out in the latest Best DSLR Camera and Best Mirrorless Interchangeable Lens Camera listings 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-400 or the E-P1. 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 table below provides a synthesis of the camera assessments of some of the best known photo-gear 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. 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.
