Going beyond this snapshot of core features and characteristics, what are the differences between the Olympus OM-D E-M5 Mark II and the Panasonic Lumix DC-GH5s? 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: Olympus E-M5 II vs Panasonic GH5s

The physical size and weight of the Olympus E-M5 II and the Panasonic GH5s are illustrated 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 II can be obtained in two different colors (black, silver), while the GH5s is only available in black.

Compare E-M5 II versus GH5s top
Comparison E-M5 II or GH5s rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Panasonic GH5s is notably larger (29 percent) than the Olympus E-M5 II. Moreover, the GH5s is substantially heavier (41 percent) than the E-M5 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. In this particular case, both cameras feature the same lens mount, so that they can use the same lenses. You can compare the optics available in the Micro Four Thirds Lens Catalog. 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-M5 II gets 310 shots out of its BLN-1 battery, while the GH5s can take 440 images on a single charge of its DMW-BLF19 power pack.

Note: Measurements and pricing do not include easily detachable parts, such as interchangeable lenses or optional viewfinders.

Any camera decision will obviously take relative prices into account. 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 56 percent) than the GH5s, 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: Olympus E-M5 II vs Panasonic GH5s

The imaging sensor is at the core of digital cameras and its size is one of the main determining factors 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 associated with larger, more expensive camera bodies and lenses.

Both cameras under consideration feature a Four Thirds sensor and have a format factor (sometimes also referred to as "crop factor") of 2.0. Within the spectrum of camera sensors, this places the review cameras among the medium-sized sensor cameras that aim to strike a balance between image quality and portability. Both cameras feature a native aspect ratio (sensor width to sensor height) of 4:3.

Olympus E-M5 II and Panasonic GH5s sensor measures

While the two cameras under review share the same sensor size, the E-M5 II offers a higher resolution of 15.9 megapixels, compared with 9.9 MP of the GH5s. This megapixels advantage translates into a 25 percent gain in linear resolution. On the other hand, these sensor specs imply that the E-M5 II has a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 3.76μm versus 4.77μm for the GH5s). Moreover, it should be noted that the GH5s is much more recent (by 2 years and 11 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 individual pixels. Coming back to sensor resolution, it should be mentioned that the GH5s has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The resolution advantage of the Olympus E-M5 II implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the E-M5 II for good quality output (200 dots per inch) amounts to 23 x 17.3 inch or 58.5 x 43.9 cm, for very good quality (250 dpi) 18.4 x 13.8 inch or 46.8 x 35.1 cm, and for excellent quality (300 dpi) 15.4 x 11.5 inch or 39 x 29.3 cm. The corresponding values for the Panasonic GH5s are 18.4 x 13.5 inch or 46.7 x 34.3 cm for good quality, 14.7 x 10.8 inch or 37.4 x 27.4 cm for very good quality, and 12.3 x 9 inch or 31.2 x 22.9 cm for excellent quality prints.

Unlike the GH5s, 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 Olympus OM-D E-M5 Mark II has a native sensitivity range from ISO 200 to ISO 25600, which can be extended to ISO 100-25600. The corresponding ISO settings for the Panasonic Lumix DC-GH5s are ISO 160 to ISO 51200, with the possibility to increase the ISO range to 80-204800.

One feature that differentiates the E-M5 II and the GH5s is in-body image stabilization (IBIS). The E-M5 II reduces the risk of handshake-induced blur with all attached lenses, while the GH5s has to rely on optical image stabilization in OIS-equipped lenses to achieve the same effect.

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-M5 II and the Panasonic GH5s 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 E-M5 II and the GH5s write their files to SDXC cards. The GH5s features dual card slots, which can be very useful in case a memory card fails. In contrast, the E-M5 II only has one slot. Moreover, both cameras support UHS-II cards (Ultra High Speed data transfer of up to 312 MB/s).

 

Connectivity comparison: Olympus E-M5 II vs Panasonic GH5s

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 Olympus OM-D E-M5 Mark II and Panasonic Lumix DC-GH5s and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the GH5s has a headphone jack, which makes it possible to attach external headphones and monitor the quality of sound during the recording process. The E-M5 II lacks such a headphone port.

Both cameras feature a PC Sync terminal to control professional strobe lights, which will be appreciated by studio photographers.

Both the E-M5 II and the GH5s are recent models that are part of the current product line-up. The E-M5 II replaced the earlier Olympus E-M5, while the GH5s 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 Olympus and Panasonic websites.


Review summary: Olympus E-M5 II vs Panasonic GH5s

So how do things add up? Which of the two cameras – the Olympus E-M5 II or the Panasonic GH5s – has the upper hand? Is one clearly better than the other? Below is a summary of the relative strengths of each of the two contestants.

ilogo

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

  • More detail: Offers more megapixels (15.9 vs 9.9MP) with a 26% higher linear resolution.
  • Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
  • High quality composites: Can combine several shots after pixel-shifting its sensor.
  • More compact: Is smaller (124x85mm vs 139x98mm) and thus needs less room in the bag.
  • Less heavy: Is lighter (by 191g or 29 percent) and hence easier to carry around.
  • Sharper images: Has hand-shake reducing image stabilization built-in.
  • More affordable: Was introduced into a lower priced category (56 percent cheaper at launch).
  • More heavily discounted: Has been available for much longer (launched in February 2015).

ilogo

Arguments in favor of the Panasonic Lumix DC-GH5s:

  • Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
  • Better video: Provides higher definition movie capture (4K/60p vs 1080/60p).
  • Better sound control: Has a headphone port that enables audio monitoring while recording.
  • More detailed viewfinder: Has higher resolution electronic viewfinder (3680k vs 2360k dots).
  • Larger viewfinder image: Features a viewfinder with a higher magnification (0.76x 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 (1620k vs 1037k dots).
  • Faster burst: Shoots at higher frequency (12 vs 10 flaps/sec) to capture the decisive moment.
  • Longer lasting: Gets more shots (440 versus 310) out of a single battery charge.
  • Faster data transfer: Supports a more advanced USB protocol (3.1 vs 2.0).
  • 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.
  • Greater peace of mind: Features a second card slot as a backup in case of memory card failure.
  • More modern: Reflects 2 years and 11 months of technical progress since the E-M5 II launch.

If the number of relative strengths (bullet points above) is taken as a guide, the GH5s is the clear winner of the contest (14 : 8 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.

E-M5 II 08:14 GH5s

How about other alternatives? Do the specifications of the Olympus E-M5 II and the Panasonic GH5s 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 says little about, for example, the shooting experience and imaging performance of the E-M5 II and the GH5s in practical situations. 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: Olympus E-M5 II vs Panasonic GH5s

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.

Notes: (+ +) highly recommended; (+) recommended; (o) reviewed; (-) not available.

The review scores listed above should be treated with care, 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.
