Going beyond this snapshot of core features and characteristics, what are the differences between the Nikon D750 and the Olympus PEN E-PL7? 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.
The side-by-side display below illustrates the physical size and weight of the Nikon D750 and the Olympus E-PL7. 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 width, height and depth dimensions are rounded to the nearest millimeter.
The E-PL7 can be obtained in two different colors (black, silver), while the D750 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-PL7 is considerably smaller (52 percent) than the Nikon D750. Moreover, the E-PL7 is substantially lighter (52 percent) than the D750. It is worth mentioning in this context that the D750 is splash and dust resistant, while the E-PL7 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 (D750) and the Micro Four Thirds Lens Catalog (E-PL7). Mirrorless cameras, such as the E-PL7, 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.

Any camera decision will naturally be influenced heavily by the price. 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-PL7 was launched at a markedly lower price (by 74 percent) than the D750, which puts it into a different market segment. 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.
The size of the imaging sensor is a crucial determinant 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. 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 more expensive and lead to bigger and heavier cameras and lenses.
Of the two cameras under consideration, the Nikon D750 features a full frame sensor and the Olympus E-PL7 a Four Thirds sensor. The sensor area in the E-PL7 is 74 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.0 and 2.0. The sensor in the D750 has a native 3:2 aspect ratio, while the one in the E-PL7 offers a 4:3 aspect.
In terms of underlying technology, both cameras are build around CMOS sensors.
With 24.2MP, the D750 offers a higher resolution than the E-PL7 (15.9MP), but the D750 nevertheless has larger individual pixels (pixel pitch of 5.97μm versus 3.76μm for the E-PL7) due to its larger sensor. It is noteworthy in this context that the two cameras were released in close succession, so that their sensors are from the same technological generation.
The resolution advantage of the Nikon D750 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the D750 for good quality output (200 dots per inch) amounts to 30.1 x 20.1 inches or 76.4 x 51 cm, for very good quality (250 dpi) 24.1 x 16.1 inches or 61.1 x 40.8 cm, and for excellent quality (300 dpi) 20.1 x 13.4 inches or 50.9 x 34 cm. The corresponding values for the Olympus E-PL7 are 23 x 17.3 inches or 58.5 x 43.9 cm for good quality, 18.4 x 13.8 inches or 46.8 x 35.1 cm for very good quality, and 15.4 x 11.5 inches or 39 x 29.3 cm for excellent quality prints.
The Nikon D750 has a native sensitivity range from ISO 100 to ISO 12800, which can be extended to ISO 50-51200. The corresponding ISO settings for the Olympus PEN E-PL7 are ISO 200 to ISO 25600, with the possibility to increase the ISO range to 100-25600.
Consistent information on actual sensor performance is available from DXO Mark for many cameras. 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 D750 provides substantially higher image quality than the E-PL7, with an overall score that is 21 points higher. This advantage is based on 2.1 bits higher color depth, 2.1 EV in additional dynamic range, and 1.8 stops in additional 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.

Many modern cameras are not only capable of taking still images, but can also record movies. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the D750 provides a higher frame rate than the E-PL7. It can shoot video footage at 1080/60p, while the Olympus is limited to 1080/30p.
Apart from body and sensor, cameras can and do differ across a range of features. For example, the D750 has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the E-PL7 relies on live view and the rear LCD for framing. That said, the E-PL7 can be equipped with an optional viewfinder – the VF-4. The adjacent table lists some of the other core features of the Nikon D750 and Olympus E-PL7 along with similar information for a selection of comparators.

One difference between the cameras concerns the presence of an on-board flash. The D750 has one, while the E-PL7 does not. While the built-in flash of the D750 is not very powerful, it can at times be useful as a fill-in light.The E-PL7 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 D750 does not have a selfie-screen.
The Nikon D750 and the Olympus E-PL7 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 D750 and the E-PL7 write their files to SDXC cards. The D750 features dual card slots, which can be very useful in case a memory card fails. In contrast, the E-PL7 only has one slot. Both cameras can use UHS-I cards, which provide for Ultra High Speed data transfer of up to 104 MB/s.
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 D750 and Olympus PEN E-PL7 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

|Olympus E-M10 II||Y||stereo||mono||-||-||micro||2.0||Y||-||-|
It is notable that the D750 has a microphone port, which is missing on the E-PL7. Such an external microphone input can help to substantially improve the quality of audio recordings when a good external microphone is used.
Studio photographers will appreciate that the Nikon D750 (unlike the E-PL7) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.
Both the D750 and the E-PL7 have been discontinued, but can regularly be found used on eBay. The E-PL7 was replaced by the Olympus E-PL8, while the D750 was followed by the Nikon D780. 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 the Nikon D750 better than the Olympus E-PL7 or vice versa? A synthesis of the relative strong points of each of the models is listed below.

- More legacy lens friendly: Can use many non-native lenses via adapters.
- More affordable: Was introduced into a lower priced category (74 percent cheaper at launch).
If the count of individual advantages (bullet points above) is taken as a guide, the D750 is the clear winner of the match-up (17 : 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 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 D750 and the Olympus E-PL7 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 incomplete and does no justice, for example, to the way the D750 or the E-PL7 perform in practice. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased.
This is why expert reviews are important. The following table reports the overall ratings of the cameras as published by some of the major 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. 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. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
