Panasonic GH4 versus Fujifilm X-T1

The Panasonic Lumix DMC-GH4 and the Fujifilm X-T1 are two digital cameras that were announced, respectively, in February 2014 and January 2014. Both the GH4 and the X-T1 are mirrorless interchangeable lens cameras that are based on a Four Thirds (GH4) and an APS-C sensor. The Panasonic has a resolution of 15.9 megapixel, whereas the Fujifilm provides 16 MP.

Body comparison

The side-by-side display below illustrates the physical size and weight of the Panasonic GH4 and the Fujifilm X-T1. Three successive views from the front, the top, and the rear are shown. All width, height and depth measures 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 side – the GH4 – 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-T1 is somewhat smaller (6 percent) than the Panasonic GH4. Moreover, the X-T1 is markedly lighter (21 percent) than the GH4. Cameras intended for semi-professional or professional use tend to be a bit bulkier in order to give them the necessary ruggedness. 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 find an overview of optics for the two cameras in the Micro Four Thirds Lens Catalog (GH4) and the Fujinon X Lens Catalog (X-T1). 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 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 GH4 was launched at a somewhat lower price (by 12 percent) than the X-T1, 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. 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 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. 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 GH4 features a Four Thirds sensor and the Fujifilm X-T1 an APS-C sensor. The sensor area in the X-T1 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 GH4 has a native 4:3 aspect ratio, while the one in the X-T1 offers a 3:2 aspect.

Sensor size

With 16MP, the X-T1 offers a higher resolution than the GH4 (15.9MP), but the X-T1 nevertheless has larger individual pixels (pixel pitch of 4.82μm versus 3.75μm for the GH4) 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 sensor resolution, it should be mentioned that the X-T1 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

Many modern cameras cannot only take still pictures, but also record videos. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the GH4 provides a higher video resolution than the X-T1. It can shoot video footage at 4K/30p, while the Fujifilm is limited to 1080/60p.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. The two cameras under review are similar with respect to both having an electronic viewfinder. However, the one in the X-T1 offers a slightly higher resolution than the one in the GH4 (2360k vs 2359k dots). The following table reports on some other key feature differences and similarities of the Panasonic GH4, the Fujifilm X-T1, and comparable cameras. If you need more detail on the specs, you can find comprehensive listings, for example, in the dpreview camera hub.

Both the GH4 and the X-T1 have been discontinued, but can regularly be found used on ebay. The X-T1 was replaced by the Fujifilm X-T2, while the GH4 was followed by the Panasonic GH5.

Summary

So what conclusions can be drawn? Is there a clear favorite between the Panasonic GH4 and the Panasonic GH4? A synthesis of the relative strong points of each of the models is listed below.


logo checkmark

Arguments in favor of the Panasonic Lumix DMC-GH4:

  • Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
  • Better video: Provides higher definition movie capture (4K/30p vs 1080/60p).
  • More flexible LCD: Has a swivel screen for odd-angle shots in portrait or landscape orientation.
  • Fewer buttons to press: Is equipped with a touch-sensitive rear screen to facilitate handling.
  • Faster shutter: Has a higher mechanical shutter speed (8000/sec vs 4000/sec) to freeze action.
  • Faster burst: Shoots at higher frequency (12 vs 8 flaps/sec) to capture the decisive moment.
  • Longer lasting: Can take more shots (500 versus 350) on a single battery charge.
  • Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
  • More affordable: Was introduced into a lower priced segment (12 percent cheaper at launch).

Reasons to prefer the Fujifilm X-T1:

  • Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
  • Better low-light imaging: Features bigger pixels on a larger sensor for better high-ISO images.
  • More detailed viewfinder: Has a higher resolution electronic viewfinder (2360k vs 2359k dots).
  • Less heavy: Has a lower weight (by 120g or 21 percent) and is thus easier to take along.

If the number of relative strengths (bullet points above) is taken as a guide, the GH4 is the clear winner of the match-up (9 : 4 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.

GH4 09:04 X-T1

In any case, while the comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it remains incomplete and does no justice, for example, to the way the GH4 or the X-T1 handle or perform in practice. 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 where reviews by experts come in. The adjacent table relays the overall verdicts of several of the most popular 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.

Care should be taken when interpreting the review scores above, though. The ratings are only valid when refering to cameras in the same category and of the same age. 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.
