Body comparison

An illustration of the physical size and weight of the Fujifilm GFX 50S II and the Pentax K-1 is provided in the side-by-side display below. The two cameras are presented according to their relative size. Three consecutive perspectives from the front, the top, and the back are available. All width, height and depth measures are rounded to the nearest millimeter.

The K-1 can be obtained in two different colors (black, silver), while the GFX 50S II is only available in black.

Size Fujifilm GFX 50S II vs Pentax K-1
Compare GFX 50S II versus K-1 top
Comparison GFX 50S II or K-1 rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Pentax K-1 is somewhat smaller (3 percent) than the Fujifilm GFX 50S II. However, the K-1 is markedly heavier (12 percent) than the GFX 50S II. 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. Hence, you might want to study and compare the specifications of available lenses in order to get the full picture of the size and weight of the two camera systems.

Concerning battery life, the GFX 50S II gets 440 shots out of its Fujifilm NP-W235 battery, while the K-1 can take 760 images on a single charge of its Pentax D-LI90 power pack. The power pack in the GFX 50S II can be charged via the USB port, so that it is not always necessary to take the battery charger along when travelling.

The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives. In case you want to display and compare another camera duo, you can use the CAM-parator app to select your camera combination among a large number of options.

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 K-1 was launched at a markedly lower price (by 55 percent) than the GFX 50S II, which puts it into a different market segment. 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. 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. Moreover, a large sensor camera will give the photographer more control over depth-of-field in the image and, thus, the ability to better isolate a subject from the background. On the downside, larger sensors tend to be associated with larger, more expensive camera bodies and lenses.

Of the two cameras under consideration, the Fujifilm GFX 50S II features a medium format sensor and the Pentax K-1 a full frame sensor. The sensor area in the K-1 is 41 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 0.79 and 1.0. The sensor in the GFX 50S II has a native 4:3 aspect ratio, while the one in the K-1 offers a 3:2 aspect.

Fujifilm GFX 50S II and Pentax K-1 sensor measures

With 51.1MP, the GFX 50S II offers a higher resolution than the K-1 (36.2MP), but the GFX 50S II nevertheless has larger individual pixels (pixel pitch of 5.33μm versus 4.88μm for the K-1) due to its larger sensor. Moreover, the GFX 50S II is a much more recent model (by 5 years and 6 months) than the K-1, 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 neither of the two cameras has an anti-alias filter installed, so they are able to capture all the detail the sensor resolves.

The resolution advantage of the Fujifilm GFX 50S II implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the GFX 50S II for good quality output (200 dots per inch) amounts to 41.3 x 31 inches or 104.9 x 78.6 cm, for very good quality (250 dpi) 33 x 24.8 inches or 83.9 x 62.9 cm, and for excellent quality (300 dpi) 27.5 x 20.6 inches or 69.9 x 52.4 cm. The corresponding values for the Pentax K-1 are 36.8 x 24.6 inches or 93.5 x 62.4 cm for good quality, 29.4 x 19.6 inches or 74.8 x 49.9 cm for very good quality, and 24.5 x 16.4 inches or 62.3 x 41.6 cm for excellent quality prints.

Both cameras have the capacity to capture high quality composite images by combining multiple shots after shifting the sensor by miniscule distances. This multi-shot, pixel-shift mode is most suitable for photography of stationary objects (landscapes, studio scenes).

The Fujifilm GFX 50S II has a native sensitivity range from ISO 100 to ISO 12800, which can be extended to ISO 50-102400. The corresponding ISO settings for the Pentax K-1 are ISO 100 to ISO 204800 (no boost).

Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors. Both cameras use a Bayer filter for capturing RGB colors on a square grid of photosensors. This arrangement is found in most digital cameras.

Many modern cameras are not only capable of taking still images, but can also record movies. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the K-1 provides a faster frame rate than the GFX 50S II. 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 range of features. For example, the GFX 50S II has an electronic viewfinder (3690k dots), while the K-1 has an optical one. Both systems have their advantages, with the electronic viewfinder making it possible to project supplementary shooting information into the framing view, whereas the optical viewfinder offers lag-free viewing and a very clear framing image. The viewfinders of both cameras offer the same field of view (100%), but the viewfinder of the GFX 50S II has a higher magnification than the one of the K-1 (0.77x vs 0.70x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The following table reports on some other key feature differences and similarities of the Fujifilm GFX 50S II, the Pentax K-1, and comparable cameras.

padding

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The GFX 50S II has a touchscreen, while the K-1 has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.

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, the GFX 50S II is one of those camera that have an additional 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 GFX 50S II and the Pentax K-1 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 GFX 50S II and the K-1 write their files to SDXC cards. Both cameras feature dual card slots, which can be very useful in case a memory card fails. The GFX 50S II supports UHS-II cards (on both slots), while the K-1 can use UHS-I cards.

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

Travel and landscape photographers will find it useful that the K-1 has an internal geolocalization sensor and can record GPS coordinates in its EXIF data.

The GFX 50S II is a recent model that features in the current product line-up of Fujifilm. In contrast, the K-1 has been discontinued (but can be found pre-owned on ebay). As a replacement in the same line of cameras, the K-1 was succeeded by the Pentax K-1 II. Further information on the features and operation of the GFX 50S II and K-1 can be found, respectively, in the Fujifilm GFX 50S II Manual (free pdf) or the online Pentax K-1 Manual.

  • More framing info: Has an electronic viewfinder that displays shooting data.
  • Larger viewfinder image: Features a viewfinder with a higher magnification (0.77x vs 0.70x).
  • More detailed LCD: Has a higher resolution rear screen (2360k vs 1037k dots).
  • Fewer buttons to press: Is equipped with a touch-sensitive rear screen to facilitate handling.
  • Less disturbing: Has an electronic shutter option for completely silent shooting.
  • Less heavy: Is lighter (by 110g or 11 percent) and hence easier to carry around.
  • Easier travel charging: Can be conveniently charged via its USB port.
  • More legacy lens friendly: Can take a broad range of non-native lenses via adapters.
  • Faster data transfer: Supports a more advanced USB protocol (3.2 vs 2.0).
  • Faster buffer clearing: Supports a more advanced SD data transfer standard (UHS-II vs UHS-I).
  • More modern: Reflects 5 years and 6 months of technical progress since the K-1 launch.

ilogo

Arguments in favor of the Pentax K-1:

  • Better video: Provides higher movie framerates (1080/60i versus 1080/30p).
  • Brighter framing: Features an optical viewfinder for clear, lag-free composition.
  • Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/4000s) to freeze action.
  • Faster burst: Shoots at higher frequency (4.4 vs 3 flaps/sec) to capture the decisive moment.
  • Longer lasting: Gets more shots (760 versus 440) out of a single battery charge.
  • Easier geotagging: Features an internal GPS sensor to log localization data.
  • More affordable: Was introduced into a lower priced category (55 percent cheaper at launch).
  • More heavily discounted: Has been around for much longer (launched in February 2016).

If the number of relative strengths (bullet points above) is taken as a guide, the GFX 50S II is the clear winner of the match-up (16 : 8 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 wedding photographer will view the differences between cameras in a way that diverges from the perspective of a travel photog, and a person interested in cityscapes has distinct needs from a macro shooter. Hence, the decision which camera is best and worth buying is often a very personal one.

GFX 50S II 16:08 K-1

How about other alternatives? Do the specifications of the Fujifilm GFX 50S II and the Pentax K-1 place the cameras among the top in their class? Find out in the latest Best Mirrorless Interchangeable Lens Camera and Best DSLR Camera listings whether the two cameras rank among the cream of the crop.

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 shooting experience and imaging performance when actually working with the GFX 50S II or the K-1. At times, user reviews, such as those published at amazon, address these issues in a useful manner, but such feedback is on many occasions incomplete, inconsistent, and unreliable.

Expert reviews

This is why expert reviews are important. The adjacent summary-table relays the overall verdicts of several of the most popular 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.

padding

The review scores listed above should be treated 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. Hence, a score should always be seen in the context of the camera's market launch date and its price, and comparisons of ratings among very different cameras or across long time periods have little meaning. Also, please note that some of the review sites have changed their methodology and reporting over time.
