Panasonic GX800 versus Fujifilm X-H1

The Panasonic Lumix DMC-GX800 (called Panasonic GX850 in some regions) and the Fujifilm X-H1 are two digital cameras that were officially introduced, respectively, in January 2017 and February 2018. Both the GX800 and the X-H1 are mirrorless interchangeable lens cameras that are based on a Four Thirds (GX800) and an APS-C sensor. The Panasonic has a resolution of 15.8 megapixel, whereas the Fujifilm provides 24 MP.

Body comparison

An illustration of the physical size and weight of the Panasonic GX800 and the Fujifilm X-H1 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 use the toggle button 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 side – the GX800 – 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 Fujifilm X-H1 is considerably larger (95 percent) than the Panasonic GX800. Moreover, the X-H1 is substantially heavier (150 percent) than the GX800. It is noteworthy in this context that the X-H1 is splash and dust-proof, while the GX800 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. A larger imaging sensor will tend to go along with bigger and heavier lenses, although exceptions exist. You can find an overview of optics for the two cameras in the Micro Four Thirds Lens Catalog (GX800) and the Fujinon X Lens Catalog (X-H1). 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 GX800 gets 210 shots out of its DMW-BLH7 battery, while the X-H1 can take 310 images on a single charge of its NP-W126S 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 comparisons there.

The listed prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The GX800 was launched at a markedly lower price (by 71 percent) than the X-H1, 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 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. 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 Panasonic GX800 features a Four Thirds sensor and the Fujifilm X-H1 an APS-C sensor. The sensor area in the X-H1 is 64 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.0 and 1.5. The sensor in the GX800 has a native 4:3 aspect ratio, while the one in the X-H1 offers a 3:2 aspect.

Sensor size

With 24MP, the X-H1 offers a higher resolution than the GX800 (15.8MP), but the X-H1 nevertheless has larger individual pixels (pixel pitch of 3.92μm versus 3.77μm for the GX800) due to its larger sensor. Moreover, the X-H1 is a somewhat more recent model (by 1 year and 1 month) than the GX800, and its sensor might 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.

Sensor resolution

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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"). The adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-cameras.

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, and both provide the same movie specifications (4K/30p).

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. For example, the X-H1 has an electronic viewfinder (3690k dots), which can be very helpful when shooting in bright sunlight. In contrast, the GX800 relies on live view and the rear LCD for framing. The table below summarizes some of the other core capabilities of the Panasonic GX800 and Fujifilm X-H1 in connection with corresponding information for a sample of similar cameras. The full specs-sheets can be found in the camera manual or, for example, in the dpreview camera hub.

Summary

So what conclusions can be drawn? Which of the two cameras – the Panasonic GX800 or the Fujifilm X-H1 – has the upper hand? A synthesis of the relative strong points of each of the models is listed below.


logo checkmark

Reasons to prefer the Panasonic Lumix DMC-GX800:

  • More compact: Is smaller (107x65mm vs 140x97mm) and thus needs less room in the bag.
  • Less heavy: Is lighter (by 404g or 60 percent) and hence easier to carry around.
  • Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
  • More affordable: Was introduced into a lower priced category (71 percent cheaper at launch).
  • More heavily discounted: Has been on the market for longer (launched in January 2017).

logo checkmark

Arguments in favor of the Fujifilm X-H1:

  • More detail: Has more megapixels (24 vs 15.8MP), which boosts linear resolution by 26%.
  • Better image quality: Is equipped with a larger and more technologically advanced sensor.
  • Easier framing: Has an electronic viewfinder for image framing and settings control.
  • Easier setting verification: Has a control panel on top to check shooting parameters.
  • More flexible LCD: Has full-flex screen for odd-angle shots in portrait or landscape orientation.
  • Faster shutter: Has higher mechanical shutter speed (8000/sec vs 500/sec) to freeze action.
  • Faster burst: Shoots at higher frequency (14 vs 10 flaps/sec) to capture the decisive moment.
  • Longer lasting: Gets more shots (310 versus 210) out of a single battery charge.
  • Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
  • Sharper images: Has stabilization technology build-in to reduce the impact of hand-shake.
  • More modern: Was introduced somewhat (1 year and 1 month) more recently.

If the count of relative strengths (bullet points above) is taken as a measure, the X-H1 is the clear winner of the contest (11 : 5 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.

GX800 05:11 X-H1

In any case, while the comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it remains partial and cannot reveal, for example, the handling experience and imaging performance when actually working with the GX800 or the X-H1. 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 where reviews by experts come in. 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. 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.
