Fujifilm X-T4 vs Panasonic GH4

The Fujifilm X-T4 and the Panasonic Lumix DMC-GH4 are two enthusiast cameras that were announced, respectively, in February 2020 and February 2014. Both the X-T4 and the GH4 are mirrorless interchangeable lens cameras that are based on an APS-C (X-T4) and a Four Thirds (GH4) sensor. The Fujifilm has a resolution of 26 megapixels, whereas the Panasonic provides 15.9 MP.

Below is an overview of the main specs of the two cameras as a starting point for the comparison.

Going beyond this snapshot of core features and characteristics, what are the differences between the Fujifilm X-T4 and the Panasonic Lumix DMC-GH4? 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

The side-by-side display below illustrates the physical size and weight of the Fujifilm X-T4 and the Panasonic GH4. 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 dimensions are rounded to the nearest millimeter.

The X-T4 can be obtained in two different colors (black, silver), while the GH4 is only available in black.

Size Fujifilm X-T4 vs Panasonic GH4
Compare X-T4 versus GH4 top
Comparison X-T4 or GH4 rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Panasonic GH4 is somewhat smaller (1 percent) than the Fujifilm X-T4. Moreover, the GH4 is markedly lighter (8 percent) than the X-T4. 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 Fujinon X Lens Catalog (X-T4) and the Micro Four Thirds Lens Catalog (GH4). 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.

The power pack in the X-T4 can be charged via the USB port, so that it is not always necessary to take the battery charger along when travelling.

The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. If you want to switch the focus of the display and review another camera pair, you can move across to the CAM-parator tool and choose from the broad selection of possible camera comparisons there.

Notes: Measurements and pricing do not include easily detachable parts, such as add-on or interchangeable lenses or optional viewfinders.

Any camera decision will naturally be influenced heavily by the price. 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 GH4 was launched at a somewhat lower price (by 12 percent) than the X-T4, which makes it more attractive for photographers on a tight budget. Normally, street prices remain initially close to the MSRP, but after a couple of months, the first discounts appear. 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 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. Further, a large sensor camera will give the photographer additional creative options when using shallow depth-of-field to isolate a subject from its background. On the downside, larger sensors are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Fujifilm X-T4 features an APS-C sensor and the Panasonic GH4 a Four Thirds sensor. The sensor area in the GH4 is 39 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.5 and 2.0. The sensor in the X-T4 has a native 3:2 aspect ratio, while the one in the GH4 offers a 4:3 aspect.

Fujifilm X-T4 and Panasonic GH4 sensor measures

With 26MP, the X-T4 offers a higher resolution than the GH4 (15.9MP), but the X-T4 nevertheless has the same individual pixel size (pixel pitch of 3.76μm) as the GH4 due to its larger sensor. It is noteworthy in this context that the X-T4 is a mch more recent model (by 6 years) than the GH4, and its sensor will 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 X-T4 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The resolution advantage of the Fujifilm X-T4 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the X-T4 for good quality output (200 dots per inch) amounts to 31.2 x 20.8 inches or 79.2 x 52.8 cm, for very good quality (250 dpi) 25 x 16.6 inches or 63.4 x 42.3 cm, and for excellent quality (300 dpi) 20.8 x 13.9 inches or 52.8 x 35.2 cm. The corresponding values for the Panasonic GH4 are 23 x 17.3 inches or 58.5 x 43.9 cm for good quality, 18.4 x 13.8 inches or 46.8 x 35.1 cm for very good quality, and 15.4 x 11.5 inches or 39 x 29.3 cm for excellent quality prints.

The X-T4 has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.

The Fujifilm X-T4 has a native sensitivity range from ISO 160 to ISO 12800, which can be extended to ISO 80-51200. The corresponding ISO settings for the Panasonic Lumix DMC-GH4 are ISO 200 to ISO 25600, with the possibility to increase the ISO range to 100-25600.

One feature that differentiates the X-T4 and the GH4 is in-body image stabilization (IBIS). The X-T4 reduces the risk of handshake-induced blur with all attached lenses, while the GH4 offers no blur reduction with lenses that themselves do not provide optical image stabilization.

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 Fujifilm X-T4 and the Panasonic GH4 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 X-T4 and the GH4 write their files to SDXC cards. The X-T4 features dual card slots, which can be very useful in case a memory card fails. In contrast, the GH4 only has one slot. The X-T4 supports UHS-II cards (on both slots), while the GH4 can use UHS-I cards.

It is notable that the GH4 has a headphone jack, which makes it possible to attach external headphones and monitor the quality of sound during the recording process. The X-T4 lacks such a headphone port.

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

The X-T4 is a recent model that features in the current product line-up of Fujifilm. In contrast, the GH4 has been discontinued (but can be found pre-owned on eBay). As a replacement in the same line of cameras, the GH4 was succeeded by the Panasonic GH5. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Fujifilm and Panasonic websites.

Review summary

So what is the bottom line? Which of the two cameras – the Fujifilm X-T4 or the Panasonic GH4 – has the upper hand? Is one clearly better than the other? The listing below highlights the relative strengths of the two models.

ilogo

Arguments in favor of the Fujifilm X-T4:

  • More detail: Offers more megapixels (26 vs 15.9MP) with a 30% 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.
  • Richer colors: The sensor size advantage translates into images with better, more accurate colors.
  • More dynamic range: Larger sensor captures a wider spectrum of light and dark details.
  • Better low-light sensitivity: Larger sensor produces good images even in poorly lit environments.
  • Better video: Provides higher movie framerates (4K/60p versus 4K/30p).
  • Better live-view autofocus: Features on-sensor phase-detection for more confident autofocus.
  • More detailed viewfinder: Has higher resolution electronic viewfinder (3690k vs 2359k dots).
  • Larger viewfinder image: Features a viewfinder with a higher magnification (0.75x vs 0.67x).
  • More detailed LCD: Has a higher resolution rear screen (1620k vs 1036k dots).
  • Faster burst: Shoots at higher frequency (15 vs 12 flaps/sec) to capture the decisive moment.
  • Easier travel charging: Can be conveniently charged via its USB port.
  • Sharper images: Has hand-shake reducing image stabilization built-in.
  • Faster data transfer: Supports a more advanced USB protocol (3.1 vs 2.0).
  • 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.
  • Faster buffer clearing: Supports a more advanced SD data transfer standard (UHS-II vs UHS-I).
  • More modern: Reflects 6 years of technical progress since the GH4 launch.

ilogo

Advantages of the Panasonic Lumix DMC-GH4:

  • Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
  • Better sound control: Has a headphone port that enables audio monitoring while recording.
  • Easier fill-in: Has a small integrated flash to brighten shadows of backlit subjects.
  • Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
  • More affordable: Was released into a lower priced segment (12 percent cheaper at launch).
  • More heavily discounted: Has been around for much longer (launched in February 2014).

If the number of relative strengths (bullet points above) is taken as a guide, the X-T4 is the clear winner of the match-up (19 : 6 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 when reflecting and deciding on a new camera. 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.

X-T4 19:06 GH4

How about other alternatives? Do the specifications of the Fujifilm X-T4 and the Panasonic GH4 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 X-T4 and the GH4 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

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], 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.

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

Care should be taken when interpreting the review scores above, though. The ratings are only valid when referring to cameras in the same category and of the same age. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, and comparisons of ratings among very different cameras or across long time periods have little meaning. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
