Body comparison

The side-by-side display below illustrates the physical size and weight of the Olympus E-M1 II and the Sony A7R V. 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.

Size Olympus E-M1 II vs Sony A7R V
Compare E-M1 II versus A7R V top
Comparison E-M1 II or A7R V rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Sony A7R V is somewhat larger (4 percent) than the Olympus E-M1 II. Moreover, the A7R V is markedly heavier (26 percent) than the E-M1 II. 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. 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 Micro Four Thirds Lens Catalog (E-M1 II) and the Sony FE Lens Catalog (A7R V). Mirrorless cameras, such as the two under consideration, have the additional advantage of having a short flange to focal plane distance, which makes it possible to mount many lenses from other systems onto the camera via adapters.

Concerning battery life, the E-M1 II gets 440 shots out of its Olympus BLH-1 battery, while the A7R V can take 530 images on a single charge of its Sony NP-FZ100 power pack. The power pack in the A7R V can be charged via the USB port, 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.

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-M1 II was launched at a markedly lower price (by 49 percent) than the A7R V, 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.

Sensor comparison

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

Of the two cameras under consideration, the Olympus E-M1 II features a Four Thirds sensor and the Sony A7R V a full frame sensor. The sensor area in the A7R V is 278 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.0 and 1.0. The sensor in the E-M1 II has a native 4:3 aspect ratio, while the one in the A7R V offers a 3:2 aspect.

Olympus E-M1 II and Sony A7R V sensor measures

With 60.2MP, the A7R V offers a higher resolution than the E-M1 II (20.2MP), but the A7R V nevertheless has larger individual pixels (pixel pitch of 3.76μm versus 3.34μm for the E-M1 II) due to its larger sensor. Moreover, the A7R V is a much more recent model (by 6 years and 1 month) than the E-M1 II, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixel-units. 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 Sony A7R V implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the A7R V for good quality output (200 dots per inch) amounts to 47.5 x 31.7 inches or 120.7 x 80.5 cm, for very good quality (250 dpi) 38 x 25.3 inches or 96.6 x 64.4 cm, and for excellent quality (300 dpi) 31.7 x 21.1 inches or 80.5 x 53.6 cm. The corresponding values for the Olympus E-M1 II 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.

Both cameras have the capacity to capture high quality composite images by combining multiple shots after shifting the sensor by miniscule distances. This multi-shot, pixel-shift mode is most suitable for photography of stationary objects (landscapes, studio scenes).

The Olympus OM-D E-M1 Mark II has a native sensitivity range from ISO 200 to ISO 25600, which can be extended to ISO 64-25600. The corresponding ISO settings for the Sony Alpha A7R V are ISO 100 to ISO 32000, with the possibility to increase the ISO range to 50-102400.

In terms of underlying technology, the E-M1 II is build around a CMOS sensor, while the A7R V uses a BSI-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.

E-M1 II versus A7R V 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 consideration, the A7R V offers substantially better image quality than the E-M1 II (overall score 20 points higher). The advantage is based on 2.8 bits higher color depth, 2 EV in additional dynamic range, and 1.3 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.

Both cameras have an articulated rear screen that can be turned to be front-facing. This feature will be particularly appreciated by vloggers and photographers who are interested in taking selfies.

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 Olympus E-M1 II and the Sony A7R V 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 E-M1 II writes its imaging data to SDXC cards, while the A7R V uses CFexpress (type A) or SDXC cards. Both cameras feature dual card slots, which can be very useful in case a memory card fails. Both cameras support UHS-II cards, which provide for Ultra High Speed data transfer of up to 312 MB/s (the second slot of the E-M1 II supports only UHS-I, though).

  • Faster burst: Shoots at higher frequency (18 vs 10 flaps/sec) to capture the decisive moment.
  • Less heavy: Is lighter (by 149g or 21 percent) and hence easier to carry around.
  • More affordable: Was introduced into a lower priced category (49 percent cheaper at launch).
  • More heavily discounted: Has been available for much longer (launched in September 2016).

ilogo

Advantages of the Sony Alpha A7R V:

  • More detail: Has more megapixels (60.2 vs 20.2MP), which boosts linear resolution by 76%.
  • Better image quality: Scores substantially higher (20 points) in the DXO overall evaluation.
  • Richer colors: Generates noticeably more natural colors (2.8 bits more color depth).
  • More dynamic range: Captures a broader range of light and dark details (2 EV of extra DR).
  • Better low-light sensitivity: Can shoot in dim conditions (1.3 stops ISO advantage).
  • Better video: Provides higher definition movie capture (8k/24p vs 4K/30p).
  • More detailed viewfinder: Has higher resolution electronic viewfinder (9440k vs 2360k dots).
  • Larger viewfinder image: Features a viewfinder with a higher magnification (0.9x vs 0.74x).
  • 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 1037k dots).
  • Longer lasting: Gets more shots (530 versus 440) out of a single battery charge.
  • Easier travel charging: Can be conveniently charged via its USB port.
  • More solid recording: Has a full-sized HDMI port for a sturdy connection to an external recorder.
  • Easier wireless transfer: Supports Bluetooth for image sharing without cables.
  • More modern: Reflects 6 years and 1 month of technical progress since the E-M1 II launch.

If the count of individual advantages (bullet points above) is taken as a guide, the A7R V is the clear winner of the contest (15 : 4 points). However, the relative importance of the various individual camera aspects will vary according to personal preferences and needs, so that you might like to apply corresponding weights to the particular features before making a decision 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.

E-M1 II 04:15 A7R V

How about other alternatives? Do the specifications of the Olympus E-M1 II and the Sony A7R V 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 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 E-M1 II or the A7R V. 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 where reviews by experts come in. 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.

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. 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.
