Nikon D40 vs Olympus E-500

The Nikon D40 and the Olympus Evolt E-500 are two digital cameras that were announced, respectively, in November 2006 and September 2005. Both are DSLR (Digital Single Lens Reflex) cameras that are based on an APS-C (D40) and a Four Thirds (E-500) sensor. The Nikon has a resolution of 6 megapixels, whereas the Olympus provides 8 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 Evolt E-500? 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 D40 and the Olympus E-500. 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 size dimensions are rounded to the nearest millimeter.

Size Nikon D40 vs Olympus E-500
Compare D40 versus E-500 top
Comparison D40 or E-500 rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Olympus E-500 is notably larger (6 percent) than the Nikon D40. However, the E-500 is markedly lighter (8 percent) than the D40. In this context, it is worth noting that neither the D40 nor the E-500 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 Four Thirds Lens Catalog (E-500).

Concerning battery life, the D40 gets 470 shots out of its EN-EL9 battery, while the E-500 can take 750 images on a single charge of its BLM-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.

Notes: Measurements and pricing do not include easily detachable parts, such as add-on or interchangeable lenses or optional viewfinders.

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 D40 was launched at a somewhat lower price (by 17 percent) than the E-500, which makes it more attractive for photographers on a tight budget. Normally, street prices remain initially close to the MSRP, but after a couple of months, the first discounts appear. 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 sensor inside a digital camera is one of the key determinants of image quality. A large sensor will generally have larger individual pixels that offer better low-light sensitivity, provide wider dynamic range, and have 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 Nikon D40 features an APS-C sensor and the Olympus E-500 a Four Thirds sensor. The sensor area in the E-500 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-500 offers a 4:3 aspect.

Nikon D40 and Olympus E-500 sensor measures

Despite having a smaller sensor, the E-500 offers a higher resolution of 8 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 5.30μm versus 7.85μm for the D40). Moreover, it should be noted that the D40 is a somewhat more recent model (by 1 year and 1 month) than the E-500, and its sensor might have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixels.

The resolution advantage of the Olympus E-500 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the E-500 for good quality output (200 dots per inch) amounts to 16.3 x 12.2 inches or 41.5 x 31.1 cm, for very good quality (250 dpi) 13.1 x 9.8 inches or 33.2 x 24.9 cm, and for excellent quality (300 dpi) 10.9 x 8.2 inches or 27.6 x 20.7 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 Evolt E-500 are ISO 100 to ISO 400, with the possibility to increase the ISO range to 100-1600.

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. The D40 and the E-500 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 D40 has a higher magnification than the one of the E-500 (0.53x vs 0.45x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The adjacent table lists some of the other core features of the Nikon D40 and Olympus E-500 along with similar information for a selection of comparators.

Review summary

So what is the bottom line? Which of the two cameras – the Nikon D40 or the Olympus E-500 – has the upper hand? Is one clearly better than the other? Below is a summary of the relative strengths of each of the two contestants.

ilogo

Arguments in favor of the Nikon D40:

  • Better image quality: Features a larger and more technologically advanced imaging 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.
  • Larger viewfinder image: Features a viewfinder with a higher magnification (0.53x vs 0.45x).
  • More affordable: Was introduced into a lower priced segment (17 percent cheaper at launch).
  • More modern: Is somewhat more recent (announced 1 year and 1 month after the E-500).

ilogo

Advantages of the Olympus Evolt E-500:

  • More detail: Has more megapixels (8 vs 6MP), which boosts linear resolution by 13%.
  • Longer lasting: Gets more shots (750 versus 470) out of a single battery charge.
  • Greater peace of mind: Features a second card slot as a backup in case of memory card failure.
  • More heavily discounted: Has been on the market for longer (launched in September 2005).

If the number of relative strengths (bullet points above) is taken as a guide, the D40 emerges as the winner of the contest (7 : 4 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.

D40 07:04 E-500

How about other alternatives? Do the specifications of the Nikon D40 and the Olympus E-500 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 technical specifications can provide a useful overview of the capabilities of different cameras, it says little about, for example, the shooting experience and imaging performance of the D40 and the E-500 in practical situations. 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], 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.

Notes: (+ +) highly recommended; (+) recommended; (o) reviewed; (..) not available.

The above review scores should be interpreted with care, though. The assessments were made in relation to similar cameras of the same technological generation. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, and comparisons of ratings among very different cameras or across long time periods have little meaning. Also, please note that some of the review sites have changed their methodology and reporting over time.
