Going beyond this snapshot of core features and characteristics, what are the differences between the Nikon Z5 and the Olympus OM-D E-M5? 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

An illustration of the physical size and weight of the Nikon Z5 and the Olympus E-M5 is provided in the side-by-side display below. 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 measures are rounded to the nearest millimeter.

The E-M5 can be obtained in two different colors (black, silver), while the Z5 is only available in black.

Size Nikon Z5 vs Olympus E-M5
Compare Z5 versus E-M5 top
Comparison Z5 or E-M5 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 is notably smaller (20 percent) than the Nikon Z5. Moreover, the E-M5 is substantially lighter (37 percent) than the Z5. 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 Z5 gets 470 shots out of its EN-EL15c battery, while the E-M5 can take 360 images on a single charge of its BLN-1 power pack. The power pack in the Z5 can be charged via the USB port, so that it is not always necessary to take the battery charger along when travelling.

The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives. 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.

Note: Measurements and pricing do not include easily detachable parts, such as add-on or 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 was somewhat cheaper (by 7 percent) than the Z5 at launch, but both cameras fall into the same price category. 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.

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. 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 more expensive and lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Nikon Z5 features a full frame sensor and the Olympus E-M5 a Four Thirds sensor. The sensor area in the E-M5 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 Z5 has a native 3:2 aspect ratio, while the one in the E-M5 offers a 4:3 aspect.

Nikon Z5 and Olympus E-M5 sensor measures

With 24.2MP, the Z5 offers a higher resolution than the E-M5 (15.9MP), but the Z5 nevertheless has larger individual pixels (pixel pitch of 5.95μm versus 3.76μm for the E-M5) due to its larger sensor. Moreover, the Z5 is a much more recent model (by 8 years and 5 months) than the E-M5, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixels.

The resolution advantage of the Nikon Z5 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the Z5 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-M5 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 Z5 has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.

The Nikon Z5 has a native sensitivity range from ISO 100 to ISO 51200, which can be extended to ISO 50-102400. The corresponding ISO settings for the Olympus OM-D E-M5 are ISO 200 to ISO 25600 (no boost).

Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors. Both cameras use a Bayer filter for capturing RGB colors on a square grid of photosensors. This arrangement is found in most digital cameras.

Z5 versus E-M5 MP

Many modern cameras cannot only take still pictures, but also record videos. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the Z5 provides a higher video resolution than the E-M5. It can shoot video footage at 4K/30p, while the Olympus is limited to 1080/60i.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. The two cameras under consideration are similar with respect to both having an electronic viewfinder. However, the one in the Z5 offers a substantially higher resolution than the one in the E-M5 (3690k vs 1440k dots). The following table reports on some other key feature differences and similarities of the Nikon Z5, the Olympus E-M5, and comparable cameras.

Notes: *) Information refers to the mechanical shutter, unless the camera only has an electronic one.

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 Z5 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 Z5 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 Z5 and the E-M5 write their files to SDXC cards. The Z5 features dual card slots, which can be very useful in case a memory card fails. In contrast, the E-M5 only has one slot. The Z5 supports UHS-II cards (on both slots), while the E-M5 can use UHS-I cards.

Connectivity comparison

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 Z5 and Olympus OM-D E-M5 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the Z5 has a microphone port, which is missing on the E-M5. Such an external microphone input can help to substantially improve the quality of audio recordings when a good external microphone is used.

The Z5 is a recent model that features in the current product line-up of Nikon. In contrast, the E-M5 has been discontinued (but can be found pre-owned on ebay). As a replacement in the same line of cameras, the E-M5 was succeeded by the Olympus E-M5 II. Further information on the features and operation of the Z5 and E-M5 can be found, respectively, in the Nikon Z5 Manual (free pdf) or the online Olympus E-M5 Manual.

Review summary

So what is the bottom line? Is the Nikon Z5 better than the Olympus E-M5 or vice versa? A synthesis of the relative strong points of each of the models is listed below.

ilogo

ilogo

Reasons to prefer the Olympus OM-D E-M5:

  • Faster burst: Shoots at higher frequency (9 vs 4.5 flaps/sec) to capture the decisive moment.
  • More compact: Is smaller (122x89mm vs 134x101mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight (by 250g or 37 percent) and is thus easier to take along.
  • More heavily discounted: Has been around for much longer (launched in February 2012).

If the count of individual advantages (bullet points above) is taken as a guide, the Z5 is the clear winner of the match-up (24 : 4 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.

Z5 24:04 E-M5

How about other alternatives? Do the specifications of the Nikon Z5 and the Olympus E-M5 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 Z5 and the E-M5 in practical situations. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased.

Expert reviews

This is why hands-on reviews by experts are important. The following table reports the overall ratings of the cameras as published by some of the major 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.

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 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.
