Body comparison

An illustration of the physical size and weight of the Pentax K-70 and the Fujifilm GFX 50S is provided in the side-by-side display below. The two cameras are presented according to their relative size. Three successive views from the front, the top, and the rear are shown. All size dimensions are rounded to the nearest millimeter.

The K-70 can be obtained in two different colors (black, silver), while the GFX 50S is only available in black.

Size Pentax K-70 vs Fujifilm GFX 50S
Compare K-70 versus GFX 50S top
Comparison K-70 or GFX 50S rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Fujifilm GFX 50S is notably larger (19 percent) than the Pentax K-70. Moreover, the GFX 50S is markedly heavier (8 percent) than the K-70. 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 K-70 gets 410 shots out of its Pentax D-LI109 battery, while the GFX 50S can take 400 images on a single charge of its Fujifilm NP-T125 power pack.

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.

The price is, of course, an important factor in any camera decision. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The K-70 was launched at a markedly lower price (by 90 percent) than the GFX 50S, 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.

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 tend to lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Pentax K-70 features an APS-C sensor and the Fujifilm GFX 50S a medium format sensor. The sensor area in the GFX 50S is 296 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.5 and 0.79. The sensor in the K-70 has a native 3:2 aspect ratio, while the one in the GFX 50S offers a 4:3 aspect.

Pentax K-70 and Fujifilm GFX 50S sensor measures

With 51.1MP, the GFX 50S offers a higher resolution than the K-70 (24MP), but the GFX 50S nevertheless has larger individual pixels (pixel pitch of 5.33μm versus 3.91μm for the K-70) due to its larger sensor. Moreover, the GFX 50S is a somewhat more recent model (by 3 months) than the K-70, 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.

The resolution advantage of the Fujifilm GFX 50S implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the GFX 50S 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-70 are 30 x 20 inches or 76.2 x 50.8 cm for good quality, 24 x 16 inches or 61 x 40.6 cm for very good quality, and 20 x 13.3 inches or 50.8 x 33.9 cm for excellent quality prints.

The K-70 has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.

Unlike the GFX 50S, the K-70 has the capacity to capture high quality composite images by combining multiple shots after shifting its sensor by miniscule distances. This multi-shot, pixel-shift mode is most suitable for photography of stationary objects (landscapes, studio scenes).

The Pentax K-70 has a native sensitivity range from ISO 100 to ISO 102400. The corresponding ISO settings for the Fujifilm GFX 50S are ISO 100 to ISO 12800, with the possibility to increase the ISO range to 50-102400.

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.

K-70 versus GFX 50S MP

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, but the K-70 provides a higher frame rate than the GFX 50S. It can shoot video 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 K-70 has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the GFX 50S relies on live view and the rear LCD for framing. That said, the GFX 50S can be equipped with an optional viewfinder – the EVF-TL1. The table below summarizes some of the other core capabilities of the Pentax K-70 and Fujifilm GFX 50S in connection with corresponding information for a sample of similar cameras.

One difference between the cameras concerns the presence of an on-board flash. The K-70 has one, while the GFX 50S does not. While the built-in flash of the K-70 is not very powerful, it can at times be useful as a fill-in light.

The K-70 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 GFX 50S 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, the GFX 50S 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 Pentax K-70 and the Fujifilm GFX 50S 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 K-70 and the GFX 50S write their files to SDXC cards. The GFX 50S features dual card slots, which can be very useful in case a memory card fails. In contrast, the K-70 only has one slot. The GFX 50S supports UHS-II cards (on both slots), while the K-70 can use UHS-I cards.

Connectivity comparison

For some imaging applications, the extent to which a camera can communicate with its environment can be an important aspect in the camera decision process.

It is notable that the GFX 50S has a headphone jack, which makes it possible to attach external headphones and monitor the quality of sound during the recording process. The K-70 lacks such a headphone port.

Studio photographers will appreciate that the Fujifilm GFX 50S (unlike the K-70) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Both the K-70 and the GFX 50S have been discontinued, but can regularly be found used on ebay. The GFX 50S was replaced by the Fujifilm GFX 50S II, while the K-70 does not have a direct successor. Further information on the features and operation of the K-70 and GFX 50S can be found, respectively, in the Pentax K-70 Manual (free pdf) or the online Fujifilm GFX 50S Manual.

Review summary

So what conclusions can be drawn? Which of the two cameras – the Pentax K-70 or the Fujifilm GFX 50S – has the upper hand? Is one clearly better than the other? A synthesis of the relative strong points of each of the models is listed below.

ilogo

Reasons to prefer the Pentax K-70:

  • High quality composites: Can combine several shots after pixel-shifting its sensor.
  • Better video: Provides higher movie framerates (1080/60i versus 1080/30p).
  • Better live-view autofocus: Features on-sensor phase-detection for more confident autofocus.
  • Easier framing: Has an optical viewfinder for image composition and settings control.
  • More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
  • Faster shutter: Has higher mechanical shutter speed (1/6000s vs 1/4000s) to freeze action.
  • Faster burst: Shoots at higher frequency (6 vs 3 flaps/sec) to capture the decisive moment.
  • More compact: Is smaller (126x93mm vs 148x94mm) and thus needs less room in the bag.
  • Sharper images: Has hand-shake reducing image stabilization built-in.
  • Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
  • More affordable: Was introduced into a lower priced category (90 percent cheaper at launch).
  • More heavily discounted: Has been on the market for longer (launched in June 2016).

ilogo

Advantages of the Fujifilm GFX 50S:

  • More detail: Has more megapixels (51.1 vs 24MP), which boosts linear resolution by 43%.
  • Better image quality: Features bigger pixels on a larger sensor for higher quality imaging.
  • Richer colors: The pixel size advantage translates into images with better, more accurate colors.
  • More dynamic range: Larger pixels capture a wider spectrum of light and dark details.
  • Better low-light sensitivity: Larger pixels means good image quality even under poor lighting.
  • Better sound control: Has a headphone port that enables audio monitoring while recording.
  • Easier setting verification: Features a control panel on top to check shooting parameters.
  • Larger screen: Has a bigger rear LCD (3.2" vs 3.0") for image review and settings control.
  • More detailed LCD: Has a higher resolution rear screen (2360k vs 921k dots).
  • Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
  • Less disturbing: Has an electronic shutter option for completely silent shooting.
  • More legacy lens friendly: Can use many non-native lenses via adapters.
  • Faster data transfer: Supports a more advanced USB protocol (3.0 vs 2.0).
  • Better studio light control: Has a PC Sync socket to connect to professional strobe lights.
  • 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: Was introduced somewhat (3 months) more recently.

If the count of relative strengths (bullet points above) is taken as a measure, the GFX 50S is the clear winner of the contest (17 : 12 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.

K-70 12:17 GFX 50S

How about other alternatives? Do the specifications of the Pentax K-70 and the Fujifilm GFX 50S place the cameras among the top in their class? Find out in the latest Best DSLR Camera and Best Mirrorless Interchangeable Lens 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 K-70 or the GFX 50S. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased.

Expert reviews

This is where reviews by experts come in. The table below provides a synthesis of the camera assessments of some of the best known photo-gear 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.

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.
