Nikon D40X vs Olympus E-P2
The Nikon D40X and the Olympus PEN E-P2 are two digital cameras that were announced, respectively, in March 2007 and November 2009. The D40X is a DSLR, while the E-P2 is a mirrorless interchangeable lens camera. The cameras are based on an APS-C (D40X) and a Four Thirds (E-P2) sensor. The Nikon has a resolution of 10 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 D40X and the Olympus PEN E-P2? 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
An illustration of the physical size and weight of the Nikon D40X and the Olympus E-P2 is provided in the side-by-side display below. The two cameras are presented according to their relative size. Three consecutive perspectives from the front, the top, and the back are available. All width, height and depth dimensions are rounded to the nearest millimeter.
The D40X can be obtained in two different colors (black, silver), while the E-P2 is available in three color-versions (black, silver, white).
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Olympus E-P2 is notably smaller (27 percent) than the Nikon D40X. Moreover, the E-P2 is markedly lighter (32 percent) than the D40X. In this context, it is worth noting that neither the D40X nor the E-P2 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 (D40X) and the Micro Four Thirds Lens Catalog (E-P2). Mirrorless cameras, such as the E-P2, 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.
Concerning battery life, the D40X gets 520 shots out of its Nikon EN-EL9 battery, while the E-P2 can take 300 images on a single charge of its Olympus BLS-1 power pack.
The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. 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.

The price is, of course, an important factor in any camera decision. The retail prices at the time of the camera’s release place the model in the market relative to other models in the producer’s line-up and the competition. The D40X was somewhat cheaper (by 9 percent) than the E-P2 at launch, but both cameras fall into the same price category. 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 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. 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 Nikon D40X features an APS-C sensor and the Olympus E-P2 a Four Thirds sensor. The sensor area in the E-P2 is 40 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 D40X has a native 3:2 aspect ratio, while the one in the E-P2 offers a 4:3 aspect.
Despite having a smaller sensor, the E-P2 offers a higher resolution of 12.2 megapixels, compared with 10 MP of the D40X. 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 6.11μm for the D40X). However, it should be noted that the E-P2 is much more recent (by 2 years and 8 months) than the D40X, 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-P2 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the E-P2 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 D40X are 19.4 x 13 inches or 49.2 x 32.9 cm for good quality, 15.5 x 10.4 inches or 39.3 x 26.3 cm for very good quality, and 12.9 x 8.6 inches or 32.8 x 21.9 cm for excellent quality prints.
The Nikon D40X has a native sensitivity range from ISO 100 to ISO 1600, which can be extended to ISO 100-3200. The corresponding ISO settings for the Olympus PEN E-P2 are ISO 100 to ISO 6400 (no boost).
In terms of underlying technology, the D40X is build around a CCD sensor, while the E-P2 uses a CMOS imager. Both cameras use a Bayer filter for capturing RGB colors on a square grid of photosensors. This arrangement is found in most digital cameras.
Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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. Of the two cameras under review, the D40X has a notably higher overall DXO score than the E-P2 (overall score 7 points higher), which gives it an advantage in terms of imaging quality. This advantage is based on 0.9 bits higher color depth, 1 EV in additional dynamic range, and 0 stops in additional low light sensitivity. The following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.

Many modern cameras cannot only take still pictures, but also record videos. The E-P2 indeed provides for movie recording, while the D40X does not. The highest resolution format that the E-P2 can use is 720/30p.
Feature comparison
Apart from body and sensor, cameras can and do differ across a range of features. For example, the D40X has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the E-P2 relies on live view and the rear LCD for framing. That said, the E-P2 can be equipped with an optional viewfinder – the VF-2. The adjacent table lists some of the other core features of the Nikon D40X and Olympus E-P2 along with similar information for a selection of comparators.

One difference between the cameras concerns the presence of an on-board flash. The D40X has one, while the E-P2 does not. While the built-in flash of the D40X is not very powerful, it can at times be useful as a fill-in light.
Concerning the storage of imaging data, both the D40X and the E-P2 write their files to SDHC cards.
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 Nikon D40X and Olympus PEN E-P2 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Both the D40X and the E-P2 have been discontinued, but can regularly be found used on ebay. The D40X was replaced by the Nikon D60 , while the E-P2 was followed by the Olympus E-P3. Further information on the features and operation of the D40X and E-P2 can be found, respectively, in the Nikon D40X Manual (free pdf) or the online Olympus E-P2 Manual.
Review summary
So what conclusions can be drawn? Is there a clear favorite between the Nikon D40X and the Olympus E-P2? Which camera is better? Below is a summary of the relative strengths of each of the two contestants.
Arguments in favor of the Nikon D40X:
- Better image quality: Scores markedly higher (7 points) in the DXO overall assessment.
- More dynamic range: Captures a larger spectrum of light and dark details (1 EV of extra DR).
- Easier framing: Has an optical viewfinder for image composition and settings control.
- Longer lasting: Can take more shots (520 versus 300) on a single battery charge.
- Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
- More heavily discounted: Has been available for much longer (launched in March 2007).
Advantages of the Olympus PEN E-P2:
- More detail: Has more megapixels (12.2 vs 10MP), which boosts linear resolution by 8%.
- 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 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 8 months of technical progress since the D40X launch.
If the count of individual advantages (bullet points above) is taken as a guide, the E-P2 emerges as the winner of the match-up (8 : 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 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 Nikon D40X and the Olympus E-P2 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 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 D40X and the E-P2 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.
Expert reviews
This is where reviews by experts come in. 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.

The review scores listed above should be treated with care, though. The ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, and comparisons of ratings among very different cameras or across long time periods have little meaning. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
