Nikon D40X vs Olympus E-600

The Nikon D40X and the Olympus E-600 are two digital cameras that were officially introduced, respectively, in March 2007 and August 2009. Both are DSLR (Digital Single Lens Reflex) cameras that are based on an APS-C (D40X) and a Four Thirds (E-600) 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 E-600? 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 Nikon D40X and the Olympus E-600. The two cameras are presented according to their relative size. Three consecutive perspectives from the front, the top, and the back are available. All size dimensions are rounded to the nearest millimeter.

The D40X can be obtained in two different colors (black, silver), while the E-600 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-600 is somewhat larger (5 percent) than the Nikon D40X. Moreover, the E-600 is slightly heavier (2 percent) than the D40X. In this context, it is worth noting that neither the D40X nor the E-600 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 Four Thirds Lens Catalog (E-600).

Concerning battery life, the D40X gets 520 shots out of its Nikon EN-EL9 battery, while the E-600 can take 500 images on a single charge of its Olympus BLS-1 power pack.

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 listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The E-600 was launched at a markedly lower price (by 38 percent) than the D40X, 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 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. 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 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-600 a Four Thirds sensor. The sensor area in the E-600 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-600 offers a 4:3 aspect.

Despite having a smaller sensor, the E-600 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-600 is much more recent (by 2 years and 5 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-600 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the E-600 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 E-600 are ISO 100 to ISO 3200 (no boost).

In terms of underlying technology, the D40X is build around a CCD sensor, while the E-600 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.

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. Of the two cameras under review, the D40X has a notably higher overall DXO score than the E-600 (overall score 8 points higher), which gives it an advantage in terms of imaging quality. This advantage is based on 0.9 bits higher color depth, 1.1 EV in additional dynamic range, and 0.1 stops of reduced low light sensitivity. The adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-cameras.

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. The D40X and the E-600 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 D40X has a higher magnification than the one of the E-600 (0.53x vs 0.48x), 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 Nikon D40X and Olympus E-600 in connection with corresponding information for a sample of similar cameras.

One feature that differentiates the E-600 and the D40X is in-body image stabilization (IBIS). The E-600 reduces the risk of handshake-induced blur with all attached lenses, while the D40X offers no blur reduction with lenses that themselves do not provide optical image stabilization.

The D40X writes its imaging data to SDHC cards, while the E-600 uses Compact Flash or xD Picture cards. The E-600 features dual card slots, which can be very useful in case a memory card fails. In contrast, the D40X only has one slot.

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 E-600 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Both the D40X and the E-600 have been discontinued, but can regularly be found used on ebay. The D40X was replaced by the Nikon D60 , while the E-600 does not have a direct successor. Further information on the features and operation of the D40X and E-600 can be found, respectively, in the Nikon D40X Manual (free pdf) or the online Olympus E-600 Manual.

Review summary

So how do things add up? Is there a clear favorite between the Nikon D40X and the Olympus E-600? Which camera is better? A synthesis of the relative strong points of each of the models is listed below.

Reasons to prefer the Nikon D40X:

• Better image quality: Scores markedly higher (8 points) in the DXO overall assessment.
• More dynamic range: Captures a larger spectrum of light and dark details (1.1 EV of extra DR).
• Larger viewfinder image: Features a viewfinder with a higher magnification (0.53x vs 0.48x).
• More heavily discounted: Has been available for much longer (launched in March 2007).

Advantages of the Olympus E-600:

• More detail: Has more megapixels (12.2 vs 10MP), which boosts linear resolution by 8%.
• 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.
• 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 category (38 percent cheaper at launch).
• More modern: Reflects 2 years and 5 months of technical progress since the D40X launch.

If the number of relative strengths (bullet points above) is taken as a guide, the E-600 is the clear winner of the contest (9 : 4 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 wedding photographer will view the differences between cameras in a way that diverges from the perspective of a travel photog, and a person interested in cityscapes has distinct needs from a macro 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-600 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 comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it remains incomplete and does no justice, for example, to the way the D40X or the E-600 perform in practice. User reviews that are available, for instance, at amazon can sometimes shed light on these issues, but such feedback is all too often partial, inconsistent, and inaccurate.

Expert reviews

This is where reviews by experts come in. The following table reports the overall ratings of the cameras as published by some of the major 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 assessments were made in relation to similar cameras of the same technological generation. A score, therefore, has to be seen in close connection to the price and market introduction time 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.
