Fujifilm GFX 50S versus Olympus E-M1 II

The Fujifilm GFX 50S and the Olympus OM-D E-M1 Mark II are two digital cameras that were officially introduced in September 2016. Both the GFX 50S and the E-M1 II are mirrorless interchangeable lens cameras that are based on a medium format (GFX 50S) and a Four Thirds (E-M1 II) sensor. The Fujifilm has a resolution of 51.1 megapixel, whereas the Olympus provides 20.2 MP. Read on to find out how these two cameras compare with respect to their size, their sensors, their features, and their reception by expert reviewers.

Body comparison: Fujifilm GFX 50S vs Olympus E-M1 II

An illustration of the physical size and weight of the Fujifilm GFX 50S and the Olympus E-M1 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 width, height and depth dimensions are rounded to the nearest millimeter. If you prefer, you can also use the toggle button to switch to a comparison in percentage terms (in this case, the camera on the left side – the GFX 50S – represents the basis for the calculations across all the size and weight measures).

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Olympus E-M1 II is notably smaller (12 percent) than the Fujifilm GFX 50S. Moreover, the E-M1 II is markedly lighter (22 percent) than the GFX 50S. 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 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 GFX 50S gets 400 shots out of its NP-T125 battery, while the E-M1 II can take 440 images on a single charge of its BLH-1 power pack.

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.

The price is, of course, an important factor in any camera decision. The retail prices at the time of the camera’s release place the model in the market relative to other models in the producer’s line-up and the competition. The E-M1 II was launched at a markedly lower price (by 69 percent) than the GFX 50S, 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: Fujifilm GFX 50S vs Olympus E-M1 II

The imaging sensor is at the core of digital cameras and its size is one of the main determining factors 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. 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 Fujifilm GFX 50S features a medium format sensor and the Olympus E-M1 II a Four Thirds sensor. The sensor area in the E-M1 II is 85 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 0.79 and 2.0. Both cameras feature a native aspect ratio (sensor width to sensor height) of 4:3.

In terms of underlying technology, both cameras are build around CMOS sensors.

Fujifilm GFX 50S and Olympus E-M1 II sensor measures

With 51.1MP, the GFX 50S offers a higher resolution than the E-M1 II (20.2MP), but the GFX 50S nevertheless has larger individual pixels (pixel pitch of 5.33μm versus 3.34μm for the E-M1 II) due to its larger sensor. It is noteworthy in this context that the two cameras were released in close succession, so that their sensors are from the same technological generation. 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.

Unlike the GFX 50S, the E-M1 II has the capacity to capture high quality composite images (50MP) 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).

Many modern cameras are not only capable of taking still images, but also of capturing video footage. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, but the E-M1 II provides a better video resolution than the GFX 50S. It can shoot movie footage at 4K/30p, while the Fujifilm is limited to 1080/30p.

 

Feature comparison: Fujifilm GFX 50S vs Olympus E-M1 II

Beyond body and sensor, cameras can and do differ across a range of features. For example, the E-M1 II has an electronic viewfinder (2360k dots), which can be very helpful when shooting in bright sunlight. In contrast, the GFX 50S relies on live view and the rear LCD for framing. That said, the GFX 50S can be equipped with an optional viewfinder – the EVF-TL1. The adjacent table lists some of the other core features of the Fujifilm GFX 50S and Olympus E-M1 II along with similar information for a selection of comparators. The full specs-sheets can be found in the camera manual or in the dpreview camera hub.

One feature that is present on the GFX 50S, but is missing on the E-M1 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 reported shutter speed and shutter burst refer to the use of the mechanical shutter. In addition, both cameras feature an electronic shutter, which makes completely silent shooting possible. However, this mode is less suitable for photographing moving objects (rolling shutter) or shooting under artificial light sources (flickering).

Both the GFX 50S and the E-M1 II write their imaging data to SDXC cards. Both cameras feature dual card slots, which can be very useful in case a memory card fails.

Both the GFX 50S and the E-M1 II are current models that good online retailers will have in stock. You can check the latest prices, for example, at amazon. The E-M1 II replaced the earlier Olympus E-M1, while the GFX 50S does not have a direct predecessor.

Review summary: Fujifilm GFX 50S vs Olympus E-M1 II

So what is the bottom line? Is the Fujifilm GFX 50S better than the Olympus E-M1 II or vice versa? Below is a summary of the relative strengths of each of the two contestants.

ilogo

Advantages of the Fujifilm GFX 50S:

  • More detail: Offers more megapixels (51.1 vs 20.2MP) with a 59% higher linear resolution.
  • Better low-light imaging: Features bigger pixels on a larger sensor for better high-ISO images.
  • 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 (2360k vs 1037k dots).

ilogo

Arguments in favor of the Olympus OM-D E-M1 Mark II:

  • High quality composites: Can combine several shots after pixel-shifting its sensor.
  • Better video: Provides higher definition movie capture (4K/30p vs 1080/30p).
  • Easier framing: Has an electronic viewfinder for image framing and settings control.
  • Faster shutter: Has higher mechanical shutter speed (8000/sec vs 4000/sec) to freeze action.
  • Faster burst: Shoots at higher frequency (18 vs 3 flaps/sec) to capture the decisive moment.
  • More compact: Is smaller (134x91mm vs 148x94mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight (by 166g or 22 percent) and is thus easier to take along.
  • Sharper images: Has stabilization technology build-in to reduce the impact of hand-shake.
  • More affordable: Was introduced into a lower priced category (69 percent cheaper at launch).

If the count of individual advantages (bullet points above) is taken as a guide, the E-M1 II is the clear winner of the contest (9 : 5 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.

GFX 50S 05:09 E-M1 II

In any case, while the specs-based evaluation of cameras is instructive in revealing their potential as photographic tools, it says nothing about, for example, the handling, responsiveness, and overall imaging quality of the GFX 50S and the E-M1 II 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. This is why hands-on reviews by experts are important. The adjacent table relays the overall verdicts of several of the most popular camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, photographyblog).

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 comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
