Going beyond this snapshot of core features and characteristics, what are the differences between the Nikon D7500 and the Olympus OM-D E-M10? 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: Nikon D7500 vs Olympus E-M10

The physical size and weight of the Nikon D7500 and the Olympus E-M10 are illustrated 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-M10 can be obtained in two different colors (black, silver), while the D7500 is only available in black.

Compare D7500 versus E-M10 top
Comparison D7500 or E-M10 rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Olympus E-M10 is considerably smaller (31 percent) than the Nikon D7500. Moreover, the E-M10 is substantially lighter (45 percent) than the D7500. It is worth mentioning in this context that the D7500 is splash and dust resistant, while the E-M10 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-M10). Mirrorless cameras, such as the E-M10, 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 D7500 gets 950 shots out of its EN-EL15a battery, while the E-M10 can take 320 images on a single charge of its BLS-5 power pack.

Note: Measurements and pricing do not include easily detachable parts, such as interchangeable lenses or optional viewfinders.

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-M10 was launched at a markedly lower price (by 46 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.

 

Sensor comparison: Nikon D7500 vs Olympus E-M10

The size of the imaging sensor is a crucial determinant 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. Furthermore, a large sensor camera will give the photographer more possibilities to use shallow depth-of-field in order to 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-M10 a Four Thirds sensor. The sensor area in the E-M10 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-M10 offers a 4:3 aspect.

Nikon D7500 and Olympus E-M10 sensor measures

With 20.7MP, the D7500 offers a higher resolution than the E-M10 (15.9MP), but the D7500 nevertheless has larger individual pixels (pixel pitch of 4.22μm versus 3.76μm for the E-M10) due to its larger sensor. Moreover, the D7500 is a much more recent model (by 3 years and 2 months) than the E-M10, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixels. Coming back to sensor resolution, it should be mentioned that neither of the two cameras has an anti-alias filter installed, so they are able to capture all the detail the 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 inch or 70.7 x 47.1 cm, for very good quality (250 dpi) 22.3 x 14.8 inch or 56.6 x 37.7 cm, and for excellent quality (300 dpi) 18.6 x 12.4 inch or 47.1 x 31.4 cm. The corresponding values for the Olympus E-M10 are 23 x 17.3 inch or 58.5 x 43.9 cm for good quality, 18.4 x 13.8 inch or 46.8 x 35.1 cm for very good quality, and 15.4 x 11.5 inch or 39 x 29.3 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 OM-D E-M10 are ISO 200 to ISO 25600, with the possibility to increase the ISO range to 100-25600.

D7500 versus E-M10 MP

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. This service is based on lab testing and assigns an overall score to each camera sensor, as well as ratings for dynamic range ("DXO Landscape"), color depth ("DXO Portrait"), and low-light sensitivity ("DXO Sports"). Of the two cameras under review, the D7500 provides substantially higher image quality than the E-M10, with an overall score that is 14 points higher. This advantage is based on 1.5 bits higher color depth, 1.7 EV in additional dynamic range, and 0.7 stops in additional low light sensitivity. The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

Many modern cameras are not only capable of taking still images, but also of capturing video footage. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the D7500 provides a higher video resolution than the E-M10. It can shoot video footage at 4K/30p, while the Olympus is limited to 1080/30p.

 

Feature comparison: Nikon D7500 vs Olympus E-M10

Beyond body and sensor, cameras can and do differ across a range of features. For example, the E-M10 has an electronic viewfinder (1440k dots), while the D7500 has an optical one. Both systems have their advantages, with the electronic viewfinder making it possible to project supplementary shooting information into the framing view, whereas the optical viewfinder offers lag-free viewing and a very clear framing image. The viewfinders of both cameras offer the same field of view (100%), but the viewfinder of the D7500 has a higher magnification than the one of the E-M10 (0.61x vs 0.58x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The following table reports on some other key feature differences and similarities of the Nikon D7500, the Olympus E-M10, and comparable cameras.

One feature that is present on the D7500, but is missing on the E-M10 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 D7500 and the Olympus E-M10 both have 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-M10 write their files to SDXC cards. Both cameras can use UHS-I cards, which provide for Ultra High Speed data transfer of up to 104 MB/s.

 

Connectivity comparison: Nikon D7500 vs Olympus E-M10

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.

It is notable that the D7500 has a microphone port, which is missing on the E-M10. 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-M10 has been discontinued (but it can be found pre-owned on eBay). As a replacement in the same line of cameras, the E-M10 was succeeded by the Olympus E-M10 II. 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.

If the count of individual advantages (bullet points above) is taken as a guide, the D7500 is the clear winner of the match-up (17 : 8 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 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 D7500 and the Olympus E-M10 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 specs-based evaluation of cameras can be instructive in revealing their potential as photographic tools, it remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the D7500 or the E-M10. 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: Nikon D7500 vs Olympus E-M10

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.

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

Care should be taken when interpreting the review scores above, 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 rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, please note that some of the review sites have changed their methodology and reporting over time.
