Nikon D40 vs Olympus E-P1
The Nikon D40 and the Olympus PEN E-P1 are two digital cameras that were announced, respectively, in November 2006 and June 2009. The D40 is a DSLR, while the E-P1 is a mirrorless interchangeable lens camera. The cameras are based on an APS-C (D40) and a Four Thirds (E-P1) sensor. The Nikon has a resolution of 6 megapixels, whereas the Olympus 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 Nikon D40 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 Nikon D40 and the Olympus E-P1. 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.
The E-P1 can be obtained in three different colors (black, silver, white), while the D40 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 (27 percent) than the Nikon D40. Moreover, the E-P1 is markedly lighter (32 percent) than the D40. In this context, it is worth noting that neither the D40 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. A larger imaging sensor will tend to go along with bigger and heavier lenses, although exceptions exist. You can compare the optics available for the two cameras in the Nikon Lens Catalog (D40) 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 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.

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 D40 was launched at a markedly lower price (by 38 percent) than the E-P1, 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 imaging sensor is a crucial determinant 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. Further, a large sensor camera will give the photographer additional creative options when using shallow depth-of-field to isolate a subject from its background. On the downside, larger sensors tend to be more expensive and lead to bigger and heavier cameras and lenses.
Of the two cameras under consideration, the Nikon D40 features an APS-C sensor and the Olympus E-P1 a Four Thirds sensor. The sensor area in the E-P1 is 39 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.5 and 2.0. The sensor in the D40 has a native 3:2 aspect ratio, while the one in the E-P1 offers a 4:3 aspect.
Despite having a smaller sensor, the E-P1 offers a higher resolution of 12.2 megapixels, compared with 6 MP of the D40. This megapixels advantage comes at the cost of a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 4.29μm versus 7.85μm for the D40). However, it should be noted that the E-P1 is much more recent (by 2 years and 7 months) than the D40, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently.
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 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 Nikon D40 are 15 x 10 inches or 38.2 x 25.4 cm for good quality, 12 x 8 inches or 30.6 x 20.3 cm for very good quality, and 10 x 6.7 inches or 25.5 x 16.9 cm for excellent quality prints.
The Nikon D40 has a native sensitivity range from ISO 200 to ISO 1600, which can be extended to ISO 200-3200. 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 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 adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-cameras.

Many modern cameras are not only capable of taking still images, but also of capturing video footage. The E-P1 indeed provides for movie recording, while the D40 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 variety of features. For example, the D40 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 Nikon D40 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 D40 has one, while the E-P1 does not. While the built-in flash of the D40 is not very powerful, it can at times be useful as a fill-in light.
Concerning the storage of imaging data, both the D40 and the E-P1 write their files to SDHC cards.
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 Nikon D40 and Olympus PEN E-P1 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Both the D40 and the E-P1 have been discontinued, but can regularly be found used on eBay. The D40 was replaced by the Nikon D40X, 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 Nikon and Olympus websites.
So how do things add up? Is there a clear favorite between the Nikon D40 and the Olympus E-P1? Which camera is better? Below is a summary of the relative strengths of each of the two contestants.
Advantages of the Nikon D40:
- More dynamic range: Captures a larger spectrum of light and dark details (0.6 EV of extra DR).
- Easier framing: Has an optical viewfinder for image composition and settings control.
- Longer lasting: Can take more shots (470 versus 300) on a single battery charge.
- Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
- More affordable: Was introduced into a lower priced category (38 percent cheaper at launch).
- More heavily discounted: Has been available for much longer (launched in November 2006).
Arguments in favor of the Olympus PEN E-P1:
- More detail: Has more megapixels (12.2 vs 6MP), which boosts linear resolution by 40%.
- 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.
- Faster burst: Shoots at higher frequency (3 vs 2.5 flaps/sec) to capture the decisive moment.
- More compact: Is smaller (121x70mm vs 124x94mm) and will fit more readily into a bag.
- Less heavy: Has a lower weight (by 167g or 32 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 7 months of technical progress since the D40 launch.
If the number of relative strengths (bullet points above) is taken as a guide, the E-P1 emerges as the winner of the match-up (9 : 6 points). However, the relevance of individual strengths will vary across photographers, so that you might want to apply your own weighing scheme to the summary points when reflecting and deciding on a new camera. 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.

In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it says little about, for example, the shooting experience and imaging performance of the D40 and the E-P1 in practical situations. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased.
This is why hands-on reviews by experts are important. The following table reports the overall ratings of the cameras as published by some of the major 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 above review scores should be interpreted 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 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.
