Nikon D7500 vs Olympus E-PL3
The Nikon D7500 and the Olympus PEN E-PL3 are two digital cameras that were announced, respectively, in April 2017 and June 2011. The D7500 is a DSLR, while the E-PL3 is a mirrorless interchangeable lens camera. The cameras are based on an APS-C (D7500) and a Four Thirds (E-PL3) sensor. The Nikon has a resolution of 20.7 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 D7500 and the Olympus PEN E-PL3? 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 D7500 and the Olympus E-PL3 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 E-PL3 can be obtained in four different colors (black, silver, red, white), while the D7500 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-PL3 is considerably smaller (50 percent) than the Nikon D7500. Moreover, the E-PL3 is substantially lighter (57 percent) than the D7500. It is worth mentioning in this context that the D7500 is splash and dust resistant, while the E-PL3 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 (D7500) and the Micro Four Thirds Lens Catalog (E-PL3). Mirrorless cameras, such as the E-PL3, 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 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 E-PL3 was launched at a markedly lower price (by 54 percent) than the D7500, 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 tend to be associated with larger, more expensive camera bodies and lenses.
Of the two cameras under consideration, the Nikon D7500 features an APS-C sensor and the Olympus E-PL3 a Four Thirds sensor. The sensor area in the E-PL3 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 D7500 has a native 3:2 aspect ratio, while the one in the E-PL3 offers a 4:3 aspect.
With 20.7MP, the D7500 offers a higher resolution than the E-PL3 (12.2MP), but the D7500 has marginally smaller individual pixels (pixel pitch of 4.22μm versus 4.29μm for the E-PL3). However, the D7500 is a much more recent model (by 5 years and 9 months) than the E-PL3, 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 D7500 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
The resolution advantage of the Nikon D7500 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the D7500 for good quality output (200 dots per inch) amounts to 27.8 x 18.6 inches or 70.7 x 47.1 cm, for very good quality (250 dpi) 22.3 x 14.8 inches or 56.6 x 37.7 cm, and for excellent quality (300 dpi) 18.6 x 12.4 inches or 47.1 x 31.4 cm. The corresponding values for the Olympus E-PL3 are 20.2 x 15.1 inches or 51.2 x 38.4 cm for good quality, 16.1 x 12.1 inches or 41 x 30.7 cm for very good quality, and 13.4 x 10.1 inches or 34.1 x 25.6 cm for excellent quality prints.
The Nikon D7500 has a native sensitivity range from ISO 100 to ISO 51200, which can be extended to ISO 50-1640000. The corresponding ISO settings for the Olympus PEN E-PL3 are ISO 200 to ISO 12800 (no boost).
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 D7500 provides substantially higher image quality than the E-PL3, with an overall score that is 34 points higher. This advantage is based on 3.4 bits higher color depth, 3.7 EV in additional dynamic range, and 1.6 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 two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the D7500 provides a higher video resolution than the E-PL3. It can shoot video footage at 4K/30p, while the Olympus is limited to 1080/60i.
Apart from body and sensor, cameras can and do differ across a range of features. For example, the D7500 has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the E-PL3 relies on live view and the rear LCD for framing. That said, the E-PL3 can be equipped with an optional viewfinder – the VF-2. The adjacent table lists some of the other core features of the Nikon D7500 and Olympus E-PL3 along with similar information for a selection of comparators.
One difference between the cameras concerns the presence of an on-board flash. The D7500 has one, while the E-PL3 does not. While the built-in flash of the D7500 is not very powerful, it can at times be useful as a fill-in light.The E-PL3 has an articulated screen that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in taking selfies. In contrast, the D7500 does not have a selfie-screen.
The Nikon D7500 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.
Concerning the storage of imaging data, both the D7500 and the E-PL3 write their files to SDXC cards. The D7500 supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the E-PL3 cannot take advantage of Ultra High Speed SD 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 D7500 and Olympus PEN E-PL3 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the D7500 has a microphone port, which is missing on the E-PL3. Such an external microphone input can help to substantially improve the quality of audio recordings when a good external microphone is used.
The D7500 is a recent model that features in the current product line-up of Nikon. In contrast, the E-PL3 has been discontinued (but can be found pre-owned on eBay). As a replacement in the same line of cameras, the E-PL3 was succeeded by the Olympus E-PL5. 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 D7500 and the Olympus E-PL3? Which camera is better? Below is a summary of the relative strengths of each of the two contestants.

If the count of individual advantages (bullet points above) is taken as a guide, the D7500 is the clear winner of the match-up (24 : 8 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.

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 D7500 and the E-PL3 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 (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.

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.
