Nikon D7100 vs Olympus E-500
The Nikon D7100 and the Olympus Evolt E-500 are two digital cameras that were announced, respectively, in February 2013 and September 2005. Both are DSLR (Digital Single Lens Reflex) cameras that are based on an APS-C (D7100) and a Four Thirds (E-500) sensor. The Nikon has a resolution of 24 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 D7100 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.
An illustration of the physical size and weight of the Nikon D7100 and the Olympus E-500 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.
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 smaller (15 percent) than the Nikon D7100. Moreover, the E-500 is substantially lighter (37 percent) than the D7100. It is worth mentioning in this context that the D7100 is splash and dust resistant, while the E-500 does not feature any corresponding weather-sealing.
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 (D7100) and the Four Thirds Lens Catalog (E-500).

The price is, of course, an important factor in any camera decision. The manufacturer’s suggested retail prices give an idea on the placement of the camera in the maker’s lineup and the broader market. The E-500 was launched at a markedly lower price (by 50 percent) than the D7100, 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.
The imaging sensor is at the core of digital cameras and its size is one of the main determining factors of image quality. All other things equal, a large sensor will have larger individual pixel-units that offer better low-light sensitivity, wider dynamic range, and 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 are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.
Of the two cameras under consideration, the Nikon D7100 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 D7100 has a native 3:2 aspect ratio, while the one in the E-500 offers a 4:3 aspect.
With 24MP, the D7100 offers a higher resolution than the E-500 (8MP), but the D7100 has smaller individual pixels (pixel pitch of 3.91μm versus 5.30μm for the E-500). However, the D7100 is a much more recent model (by 7 years and 4 months) than the E-500, and its sensor will have benefitted from technological advances during this time that enhance the light gathering capacity of its pixels. Coming back to sensor resolution, it should be mentioned that the D7100 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
The resolution advantage of the Nikon D7100 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the D7100 for good quality output (200 dots per inch) amounts to 30 x 20 inch or 76.2 x 50.8 cm, for very good quality (250 dpi) 24 x 16 inch or 61 x 40.6 cm, and for excellent quality (300 dpi) 20 x 13.3 inch or 50.8 x 33.9 cm. The corresponding values for the Olympus E-500 are 16.3 x 12.2 inch or 41.5 x 31.1 cm for good quality, 13.1 x 9.8 inch or 33.2 x 24.9 cm for very good quality, and 10.9 x 8.2 inch or 27.6 x 20.7 cm for excellent quality prints.
The Nikon D7100 has a native sensitivity range from ISO 100 to ISO 6400, which can be extended to ISO 50-25600. 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.
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. 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 are not only capable of taking still images, but also of capturing video footage. The D7100 indeed provides movie recording capabilities, while the E-500 does not. The highest resolution format that the D7100 can use is 1080/60p.
Apart from body and sensor, cameras can and do differ across a range of features. The D7100 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 viewfinder in the D7100 offers a wider field of view (100%) than the one in the E-500 (95%), so that a larger proportion of the captured image is visible in the finder. In addition, the viewfinder of the D7100 has a higher magnification (0.63x 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 D7100 and Olympus E-500 along with similar information for a selection of comparators.

One feature that is present on the D7100, but is missing on the E-500 is a top-level LCD. While being, of course, smaller than the rear screen, the control panel conveys some of the essential shooting information and can be convenient for quick and easy settings verification.
The Nikon D7100 has an intervalometer built-in. This enables the photographer to capture time lapse sequences, such as flower blooming, a sunset or moon rise, without purchasing an external camera trigger and related software.
The D7100 writes its imaging data to SDXC cards, while the E-500 uses Compact Flash or xD Picture cards. Both cameras feature dual card slots, which can be very useful in case a memory card fails.
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 D7100 and Olympus Evolt E-500 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Both the D7100 and the E-500 have been discontinued, but can regularly be found used on eBay. The E-500 was replaced by the Olympus E-510, while the D7100 was followed by the Nikon D7200. 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 what conclusions can be drawn? Is there a clear favorite between the Nikon D7100 and the Olympus E-500? Which camera is better? Below is a summary of the relative strengths of each of the two contestants.
Arguments in favor of the Nikon D7100:

- More heavily discounted: Has been around for much longer (launched in September 2005).
If the count of individual advantages (bullet points above) is taken as a guide, the D7100 is the clear winner of the match-up (18 : 5 points). However, the relative importance of the various individual camera aspects will vary according to personal preferences and needs, so that you might like to apply corresponding weights to the particular features before making a decision 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 D7100 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 D7100 and the E-500 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.
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 (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 were established in reference to similarly priced cameras that were available in the market at the time of the review. 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, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
