Going beyond this snapshot of core features and characteristics, what are the differences between the Nikon Z7 and the Olympus OM-D E-M5 Mark II? 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 Z7 vs Olympus E-M5 II

An illustration of the physical size and weight of the Nikon Z7 and the Olympus E-M5 II is provided in the side-by-side display below. The two cameras are presented according to their relative size. Three successive views from the front, the top, and the rear are shown. All size dimensions are rounded to the nearest millimeter.

The E-M5 II can be obtained in two different colors (black, silver), while the Z7 is only available in black.

Compare Z7 versus E-M5 II top
Comparison Z7 or E-M5 II rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Olympus E-M5 II is notably smaller (22 percent) than the Nikon Z7. Moreover, the E-M5 II is markedly lighter (31 percent) than the Z7. In this context, it is worth noting that both cameras are splash and dust-proof and can, hence, be used in inclement weather conditions or harsh environments.

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. Hence, you might want to study and compare the specifications of available lenses in order to get the full picture of the size and weight of the two camera systems.

Concerning battery life, the Z7 gets 330 shots out of its EN-EL15b battery, while the E-M5 II can take 310 images on a single charge of its BLN-1 power pack. The power pack in the Z7 can be charged via the USB port, so that it is not always necessary to take the battery charger along when travelling.

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. If you want to switch the focus of the display and review another camera pair, just select a new right or left comparator from among the camera models in the table. Alternatively, you can also move across to the CAM-parator tool and choose from the broad selection of possible camera comparisons there.

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-M5 II was launched at a markedly lower price (by 68 percent) than the Z7, 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.

 

Sensor comparison: Nikon Z7 vs Olympus E-M5 II

The size of the imaging sensor is a crucial determinant of image quality. A large sensor will tend to have larger individual pixels that provide better low-light sensitivity, wider dynamic range, and richer color-depth than smaller pixel-units in a sensor of the same technological generation. Further, a large sensor camera will give the photographer additional creative options when using shallow depth-of-field to isolate a subject from its 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 Z7 features a full frame sensor and the Olympus E-M5 II a Four Thirds sensor. The sensor area in the E-M5 II 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 Z7 has a native 3:2 aspect ratio, while the one in the E-M5 II offers a 4:3 aspect.

Nikon Z7 and Olympus E-M5 II sensor measures

With 45.4MP, the Z7 offers a higher resolution than the E-M5 II (15.9MP), but the Z7 nevertheless has larger individual pixels (pixel pitch of 4.35μm versus 3.76μm for the E-M5 II) due to its larger sensor. Moreover, the Z7 is a much more recent model (by 3 years and 6 months) than the E-M5 II, 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 the Z7 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The resolution advantage of the Nikon Z7 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the Z7 for good quality output (200 dots per inch) amounts to 41.3 x 27.5 inch or 104.9 x 69.9 cm, for very good quality (250 dpi) 33 x 22 inch or 83.9 x 55.9 cm, and for excellent quality (300 dpi) 27.5 x 18.3 inch or 69.9 x 46.6 cm. The corresponding values for the Olympus E-M5 II 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 Z7 has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.

Unlike the Z7, the E-M5 II has the capacity to capture high quality composite images (40MP) by combining multiple shots after shifting its sensor by miniscule distances. This multi-shot, pixel-shift mode is most suitable for photography of stationary objects (landscapes, studio scenes).

The Nikon Z7 has a native sensitivity range from ISO 64 to ISO 25600, which can be extended to ISO 32-102400. The corresponding ISO settings for the Olympus OM-D E-M5 Mark II are ISO 200 to ISO 25600, with the possibility to increase the ISO range to 100-25600.

Z7 versus E-M5 II MP

Consistent information on actual sensor performance is available from DXO Mark for many cameras. This service determines an overall sensor rating, as well as sub-scores for low-light sensitivity ("DXO Sports"), dynamic range ("DXO Landscape"), and color depth ("DXO Portrait"). Of the two cameras under review, the Z7 provides substantially higher image quality than the E-M5 II, with an overall score that is 26 points higher. This advantage is based on 3.3 bits higher color depth, 2.1 EV in additional dynamic range, and 1.7 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.

One feature that is present on the Z7, but is missing on the E-M5 II 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 E-M5 II 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 Z7 does not have a selfie-screen.

The reported shutter speed information refers to the use of the mechanical shutter. Yet, some cameras only have an electronic shutter, while others have an electronic shutter in addition to a mechanical one. In fact, the E-M5 II is one of those camera that have an additional electronic shutter, which makes completely silent shooting possible. However, this mode is less suitable for photographing moving objects (risk of rolling shutter) or shooting under artificial light sources (risk of flickering).

The Nikon Z7 and the Olympus E-M5 II 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.

The Z7 writes its imaging data to XQD cards, while the E-M5 II uses SDXC cards.

 

Connectivity comparison: Nikon Z7 vs Olympus E-M5 II

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 Z7 has a headphone jack, which is not present on the E-M5 II This port makes it possible to attach external headphones and monitor the quality of sound during the recording process.

Studio photographers will appreciate that the Olympus E-M5 II (unlike the Z7) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Both the Z7 and the E-M5 II are recent models that are part of the current product line-up. The E-M5 II replaced the earlier Olympus E-M5, while the Z7 does not have a direct predecessor. 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 Z7 is the clear winner of the match-up (17 : 10 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.

Z7 17:10 E-M5 II

How about other alternatives? Do the specifications of the Nikon Z7 and the Olympus E-M5 II place the cameras among the top in their class? Find out in the latest Best Mirrorless Interchangeable Lens Camera listing whether the two cameras rank among the cream of the crop.

In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it remains incomplete and does no justice, for example, to the way the Z7 or the E-M5 II perform in practice. 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: Nikon Z7 vs Olympus E-M5 II

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 assessments were made in relation to similar cameras of the same technological generation. 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, please note that some of the review sites have changed their methodology and reporting over time.
