Compare Z7 versus E-M10 IV top
Comparison Z7 or E-M10 IV 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 IV is notably smaller (24 percent) than the Nikon Z7. Moreover, the E-M10 IV is substantially lighter (43 percent) than the Z7. It is worth mentioning in this context that the Z7 is splash and dust resistant, while the E-M10 IV 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. 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 Nikon EN-EL15b battery, while the E-M10 IV can take 360 images on a single charge of its Olympus BLS-50 power pack. The battery packs of both cameras can be charged via USB, which can be very convenient when travelling.

The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. In case you want to display and compare another camera duo, you can use the CAM-parator app to select your camera combination among a large number of options.

Any camera decision will naturally be influenced heavily by the price. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The E-M10 IV was launched at a markedly lower price (by 79 percent) than the Z7, 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

The size of the sensor inside a digital camera is one of the key determinants 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 associated with larger, more expensive camera bodies and lenses.

Of the two cameras under consideration, the Nikon Z7 features a full frame sensor and the Olympus E-M10 IV a Four Thirds sensor. The sensor area in the E-M10 IV 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-M10 IV offers a 4:3 aspect.

Nikon Z7 and Olympus E-M10 IV sensor measures

With 45.4MP, the Z7 offers a higher resolution than the E-M10 IV (20.2MP), but the Z7 nevertheless has larger individual pixels (pixel pitch of 4.35μm versus 3.34μm for the E-M10 IV) due to its larger sensor. However, the E-M10 IV is a somewhat more recent model (by 1 year and 11 months) than the Z7, and its sensor might 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 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 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 inches or 104.9 x 69.9 cm, for very good quality (250 dpi) 33 x 22 inches or 83.9 x 55.9 cm, and for excellent quality (300 dpi) 27.5 x 18.3 inches or 69.9 x 46.6 cm. The corresponding values for the Olympus E-M10 IV are 25.9 x 19.4 inches or 65.8 x 49.4 cm for good quality, 20.7 x 15.6 inches or 52.7 x 39.5 cm for very good quality, and 17.3 x 13 inches or 43.9 x 32.9 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.

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-M10 Mark IV are ISO 200 to ISO 25600, with the possibility to increase the ISO range to 100-25600.

In terms of underlying technology, the Z7 is build around a BSI-CMOS sensor, while the E-M10 IV uses a CMOS imager. Both cameras use a Bayer filter for capturing RGB colors on a square grid of photosensors. This arrangement is found in most digital cameras.

Z7 versus E-M10 IV 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"). The adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-cameras.

One feature that is present on the Z7, but is missing on the E-M10 IV 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-M10 IV 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, both cameras under consideration feature an 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-M10 IV 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-M10 IV uses SDXC cards.

It is notable that the Z7 has a microphone port, which is missing on the E-M10 IV. Such an external microphone input can help to substantially improve the quality of audio recordings when a good external microphone is used.

The E-M10 IV is a recent model that features in the current product line-up of Olympus. In contrast, the Z7 has been discontinued (but can be found pre-owned on ebay). As a replacement in the same line of cameras, the Z7 was succeeded by the Nikon Z7 II. Further information on the features and operation of the Z7 and E-M10 IV can be found, respectively, in the Nikon Z7 Manual (free pdf) or the online Olympus E-M10 IV Manual.

Review summary

So how do things add up? Is there a clear favorite between the Nikon Z7 and the Olympus E-M10 IV? Which camera is better? Below is a summary of the relative strengths of each of the two contestants.

ilogo

Advantages of the Nikon Z7:

  • More detail: Offers more megapixels (45.4 vs 20.2MP) with a 53% higher linear resolution.
  • Better image quality: Features bigger pixels on a larger sensor for higher quality imaging.
  • Richer colors: The pixel size advantage translates into images with better, more accurate colors.
  • More dynamic range: Larger pixels capture a wider spectrum of light and dark details.
  • Better low-light sensitivity: Larger pixels means good image quality even under poor lighting.
  • Better live-view autofocus: Features on-sensor phase-detection for more confident autofocus.
  • Better sound: Can connect to an external microphone for higher quality sound recording.
  • Better sound control: Has a headphone port that enables audio monitoring while recording.
  • More detailed viewfinder: Has higher resolution electronic viewfinder (3690k vs 2360k dots).
  • Larger viewfinder image: Features a viewfinder with a higher magnification (0.80x vs 0.62x).
  • Easier setting verification: Features an LCD display on top to control shooting parameters.
  • Larger screen: Has a bigger rear LCD (3.2" vs 3.0") for image review and settings control.
  • More detailed LCD: Has a higher resolution rear screen (2100k vs 1040k dots).
  • Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/4000s) to freeze action.

  • Faster data transfer: Supports a more advanced USB protocol (3.1 vs 2.0).
  • More heavily discounted: Has been on the market for longer (launched in August 2018).

ilogo

Arguments in favor of the Olympus OM-D E-M10 Mark IV:

  • More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
  • Faster burst: Shoots at higher frequency (15 vs 9 flaps/sec) to capture the decisive moment.
  • More compact: Is smaller (122x84mm vs 134x101mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight (by 292g or 43 percent) and is thus easier to take along.
  • Easier fill-in: Has a small integrated flash to brighten shadows of backlit subjects.
  • More affordable: Was introduced into a lower priced category (79 percent cheaper at launch).
  • More modern: Was introduced somewhat (1 year and 11 months) more recently.

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 : 7 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 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 17:07 E-M10 IV

How about other alternatives? Do the specifications of the Nikon Z7 and the Olympus E-M10 IV 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 says little about, for example, the shooting experience and imaging performance of the Z7 and the E-M10 IV 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.

Expert reviews

This is why hands-on reviews by experts are important. The adjacent summary-table relays the overall verdicts of several of the most popular camera review sites (amateurphotographer [AP], cameralabs [CL], digitalcameraworld [DCW], 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 above review scores should be interpreted 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 comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
