Fujifilm GFX 50S versus Panasonic GM1

The Fujifilm GFX 50S and the Panasonic Lumix DMC-GM1 are two digital cameras that were officially introduced, respectively, in September 2016 and October 2013. Both the GFX and the GM1 are mirrorless interchangeable lens cameras that are based on a medium format (GFX) and a Four Thirds sensor. The Fujifilm has a resolution of 51.1 megapixel, whereas the Panasonic provides 15.8 MP.

Body comparison

An illustration of the physical size and weight of the Fujifilm GFX 50S and the Panasonic GM1 is provided in the side-by-side display below. Three successive views from the front, the top, and the rear are shown. All size dimensions are rounded to the nearest millimeter. You can also toggle the display to switch to a percentage comparison if you prefer that the measures are being expressed in relative terms (in this case, the camera on the left – the GFX – represents 100 percent 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 Panasonic GM1 is considerably smaller (61 percent) than the Fujifilm GFX 50S. Moreover, the GM1 is substantially lighter (72 percent) than the GFX. Cameras that are aimed at professionals or semi-pros tend to be a bit bulkier in order to give them the necessary environmental and shock resistance. It is worth mentioning in this context that the GFX is splash and dust resistant, while the GM1 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 the specifications of available lenses in order to get the full picture of the size and weight of the two camera systems.

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 comparisons there.

The listed prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The GM1 was launched at a markedly lower price (by 88 percent) than the GFX, 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. 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 are more costly to manufacture and tent to 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 Panasonic GM1 a Four Thirds sensor. The sensor area in the GM1 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.

Sensor size

With 51.1MP, the GFX offers a higher resolution than the GM1 (15.8MP), but the GFX nevertheless has larger individual pixels (pixel pitch of 5.33μm versus 3.77μm for the GM1) due to its larger sensor. Moreover, the GFX is a somewhat more recent model (by 2 years and 11 months) than the GM1, and its sensor might have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixels. Coming back to sensor resolution, it should be mentioned that the GFX has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

Many modern cameras are not only capable of taking still images, but also of capturing video footage. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the GM1 provides a faster frame rate than the GFX. It can shoot movie footage at 1080/60i, while the Fujifilm is limited to 1080/30p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. The GFX and the GM1 are similar in the sense that neither of the two has a viewfinder. The images are, thus, framed using live view on the rear LCD. The adjacent table lists some of the other core features of the Fujifilm GFX 50S and Panasonic GM1 along with similar information for a selection of comparators. If needed, the dpreview camera hub, for example, contains further detail on the cameras' specs.

The GFX is a current model that online retailers, such as amazon, will have in stock. In contrast, the GM1 has been discontinued (but it can be found pre-owned on ebay). As a replacement in the same line of cameras, the GM1 was succeeded by the Panasonic GM5.

Summary

So how do things add up? Which of the two cameras – the Fujifilm GFX 50S or the Panasonic GM1 – has the upper hand? The listing below highlights the relative strengths of the two models.


logo checkmark

Arguments in favor of the Fujifilm GFX 50S:

  • More detail: Offers more megapixels (51.1 vs 15.8MP) with a 80% higher linear resolution.
  • Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
  • Better image quality: Features a larger and more technologically advanced imaging sensor.
  • Easier setting verification: Has 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 1036k dots).
  • More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
  • Faster shutter: Has a higher mechanical shutter speed (4000/sec vs 500/sec) to freeze action.
  • Longer lasting: Can take more shots (400 versus 230) on a single battery charge.
  • Better sealing: Is weather sealed to enable shooting in dusty or wet environments.
  • More modern: Reflects 2 years and 11 months of technical progress since the GM1 launch.

Advantages of the Panasonic Lumix DMC-GM1:

  • Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
  • Better video: Provides higher movie framerates (1080/60i vs 1080/30p).
  • Faster burst: Shoots at higher frequency (5 vs 3 flaps/sec) to capture the decisive moment.
  • More compact: Is smaller (99x55mm vs 148x94mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight (by 536g or 72 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 (88 percent cheaper at launch).
  • More heavily discounted: Has been around for much longer (launched in October 2013).

If the count of individual advantages (bullet points above) is taken as a guide, the GFX emerges as the winner of the contest (11 : 8 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.

GFX 11:08 GM1

In any case, while the specs-based evaluation of cameras is instructive in revealing their potential as photographic tools, it remains partial and cannot reveal, for example, the handling experience and imaging performance when actually working with the GFX or the GM1. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased. This is why expert reviews are important. The table below summarizes the assessments of some of the best known camera review sites. The detailed reviews can be accessed, respectively, on the websites of cameralabs.com, dpreview.com, ephotozine.com, imaging-resource.com, and photographyblog.com.

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. 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. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
