Body comparison

The side-by-side display below illustrates the physical size and weight of the Panasonic GH3 and the Fujifilm X-T3. 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 X-T3 can be obtained in two different colors (black, silver), while the GH3 is only available in black.

Compare GH3 versus X-T3 top
Comparison GH3 or X-T3 rear

In this particular case, the Panasonic GH3 and the Fujifilm X-T3 have exactly the same width and height, and, thus, have identically-sized bodies. However, the Fujifilm is slightly lighter (2 percent) than the Panasonic. 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 Micro Four Thirds Lens Catalog (GH3) and the Fujinon X Lens Catalog (X-T3). 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 GH3 gets 540 shots out of its Panasonic DMW-BLF19 battery, while the X-T3 can take 390 images on a single charge of its Fujifilm NP-W126S power pack. The power pack in the X-T3 can be charged via the USB port, which can be very convenient when travelling.

The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones.

Any camera decision will naturally be influenced heavily by the price. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The GH3 was launched at a somewhat lower price (by 13 percent) than the X-T3, which makes it more attractive for photographers on a tight budget. 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

The size of the imaging sensor is a crucial determinant 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. 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 Panasonic GH3 features a Four Thirds sensor and the Fujifilm X-T3 an APS-C sensor. The sensor area in the X-T3 is 63 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 GH3 has a native 4:3 aspect ratio, while the one in the X-T3 offers a 3:2 aspect.

Panasonic GH3 and Fujifilm X-T3 sensor measures

With 26MP, the X-T3 offers a higher resolution than the GH3 (15.9MP), but the X-T3 nevertheless has the same individual pixel size (pixel pitch of 3.76μm) as the GH3 due to its larger sensor. Moreover, the X-T3 is a much more recent model (by 5 years and 11 months) than the GH3, and its sensor will have benefitted from technological advances during this time that enhance the light gathering capacity of its pixel-units. Coming back to sensor resolution, it should be mentioned that the X-T3 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The resolution advantage of the Fujifilm X-T3 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the X-T3 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 GH3 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-T3 has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.

The Panasonic Lumix DMC-GH3 has a native sensitivity range from ISO 200 to ISO 12800, which can be extended to ISO 125-25600. The corresponding ISO settings for the Fujifilm X-T3 are ISO 160 to ISO 12800, with the possibility to increase the ISO range to 80-51200.

In terms of underlying technology, the GH3 is build around a CMOS sensor, while the X-T3 uses a BSI-CMOS imager. Like most digital cameras, the GH3 uses a Bayer filter for capturing RGB colors on a square grid of photosensors. In contrast, the X-T3 employs a more randomized X-Trans layout of photosites, which according to Fujifilm helps to minimize moiré.

GH3 versus X-T3 MP

For many cameras, data on sensor performance has been reported by DXO Mark. 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.

Note: *) Information refers to the mechanical shutter, unless the camera only has an electronic one.

One difference between the cameras concerns the presence of an on-board flash. The GH3 has one, while the X-T3 does not. While the built-in flash of the GH3 is not very powerful, it can at times be useful as a fill-in light.

The GH3 has an articulated LCD that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in snapping selfies. In contrast, the X-T3 does not have a selfie-screen.

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 Panasonic GH3 and the Fujifilm X-T3 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 GH3 and the X-T3 write their files to SDXC cards. The X-T3 features dual card slots, which can be very useful in case a memory card fails. In contrast, the GH3 only has one slot. The X-T3 supports UHS-II cards (on both slots), while the GH3 can use UHS-I cards.

  • More affordable: Was introduced into a lower priced segment (13 percent cheaper at launch).
  • More heavily discounted: Has been available for much longer (launched in September 2012).

ilogo

Reasons to prefer the Fujifilm X-T3:

  • More detail: Has more megapixels (26 vs 15.9MP), which boosts linear resolution by 30%.
  • Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
  • Better image quality: Is equipped with a larger and more technologically advanced 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 definition movie capture (4K/60p vs 1080/60p).
  • Better live-view autofocus: Features on-sensor phase-detection for more confident autofocus.
  • More detailed viewfinder: Has higher resolution electronic viewfinder (3690k vs 1746k 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 (1040k vs 614k dots).
  • Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/4000s) to freeze action.
  • Faster burst: Shoots at higher frequency (11 vs 6 flaps/sec) to capture the decisive moment.
  • Easier travel charging: Can be conveniently charged via its USB port.
  • 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 5 years and 11 months of technical progress since the GH3 launch.

If the number of relative strengths (bullet points above) is taken as a guide, the X-T3 is the clear winner of the contest (19 : 6 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 sports photographer will view the differences between cameras in a way that diverges from the perspective of a street photog, and a person interested in family portraits has distinct needs from a landscape shooter. Hence, the decision which camera is best and worth buying is often a very personal one.

GH3 06:19 X-T3

How about other alternatives? Do the specifications of the Panasonic GH3 and the Fujifilm X-T3 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 comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the GH3 or the X-T3. 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], digitalcameraworld [DCW], 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.

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

The above review scores should be interpreted with care, though. The ratings are only valid when referring to cameras in the same category and of the same age. Hence, a score should always be seen in the context of the camera's market launch date and its price, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, please note that some of the review sites have changed their methodology and reporting over time.
