Body comparison

An illustration of the physical size and weight of the Fujifilm GFX 100 and the Pentax K-70 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 dimensions are rounded to the nearest millimeter.

The K-70 can be obtained in two different colors (black, silver), while the GFX 100 is only available in black.

Size Fujifilm GFX 100 vs Pentax K-70
Compare GFX 100 versus K-70 top
Comparison GFX 100 or K-70 rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Pentax K-70 is considerably smaller (48 percent) than the Fujifilm GFX 100. Moreover, the K-70 is substantially lighter (48 percent) than the GFX 100. 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 100 gets 800 shots out of its Fujifilm NP-T125 battery, while the K-70 can take 410 images on a single charge of its Pentax D-LI109 power pack. As can be seen in the images above, the GFX 100 has a battery grip built in. This facilitates image-taking in portrait orientation and gives it additional battery power. The power pack in the GFX 100 can be charged via the USB port, so that it is not always necessary to take the battery charger along when travelling.

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. 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 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-70 was launched at a markedly lower price (by 94 percent) than the GFX 100, which puts it into a different market segment. 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. 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 tend to be more expensive and lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Fujifilm GFX 100 features a medium format sensor and the Pentax K-70 an APS-C sensor. The sensor area in the K-70 is 75 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 0.79 and 1.5. The sensor in the GFX 100 has a native 4:3 aspect ratio, while the one in the K-70 offers a 3:2 aspect.

Fujifilm GFX 100 and Pentax K-70 sensor measures

With 101.8MP, the GFX 100 offers a higher resolution than the K-70 (24MP), but the GFX 100 has smaller individual pixels (pixel pitch of 3.76μm versus 3.91μm for the K-70). However, the GFX 100 is a much more recent model (by 2 years and 11 months) than the K-70, and its sensor will have benefitted from technological advances during this time that 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 100 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the GFX 100 for good quality output (200 dots per inch) amounts to 58.2 x 43.7 inches or 147.9 x 110.9 cm, for very good quality (250 dpi) 46.6 x 34.9 inches or 118.3 x 88.8 cm, and for excellent quality (300 dpi) 38.8 x 29.1 inches or 98.6 x 74 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.

Unlike the GFX 100, 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 Fujifilm GFX 100 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-70 are ISO 100 to ISO 102400 (no boost).

In terms of underlying technology, the GFX 100 is build around a BSI-CMOS sensor, while the K-70 uses a CMOS imager. Both cameras use a Bayer filter for capturing RGB colors on a square grid of photosensors. This arrangement is found in most digital cameras.

GFX 100 versus K-70 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.

Many modern cameras cannot only take still pictures, but also record videos. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the GFX 100 provides a higher video resolution than the K-70. It can shoot video footage at 4K/30p, while the Pentax is limited to 1080/60i.

Feature comparison

Beyond 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 100 relies on live view and the rear LCD for framing. That said, the GFX 100 can be equipped with an optional viewfinder – the EVF-GFX2. The following table reports on some other key feature differences and similarities of the Fujifilm GFX 100, the Pentax K-70, and comparable cameras.

One feature that is present on the GFX 100, but is missing on the K-70 is a top-level LCD. While being, of course, smaller than the rear screen, the control panel conveys some of the essential shooting information and can be convenient for quick and easy settings verification.

The K-70 has an articulated screen that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in taking selfies. In contrast, the GFX 100 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 100 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 100 and the Pentax K-70 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 100 and the K-70 write their files to SDXC cards. The GFX 100 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 100 supports UHS-II cards (on both slots), while the K-70 can use UHS-I cards.

It is notable that the GFX 100 has a headphone jack, which is not present on the K-70 This port makes it possible to attach external headphones and monitor the quality of sound during the recording process.

Studio photographers will appreciate that the Fujifilm GFX 100 (unlike the K-70) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Both the GFX 100 and the K-70 have been discontinued, but can regularly be found used on ebay. The GFX 100 was replaced by the Fujifilm GFX 100 II, while the K-70 does not have a direct successor. Further information on the features and operation of the GFX 100 and K-70 can be found, respectively, in the Fujifilm GFX 100 Manual (free pdf) or the online Pentax K-70 Manual.

  • More compact: Is smaller (126x93mm vs 156x144mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight (by 632g or 48 percent) and is thus easier to take along.
  • Easier fill-in: Has a small integrated flash to brighten shadows of backlit subjects.
  • More affordable: Was introduced into a lower priced category (94 percent cheaper at launch).
  • More heavily discounted: Has been around for much longer (launched in June 2016).

If the count of relative strengths (bullet points above) is taken as a measure, the GFX 100 is the clear winner of the match-up (22 : 10 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 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 100 22:10 K-70

How about other alternatives? Do the specifications of the Fujifilm GFX 100 and the Pentax K-70 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 specs-based evaluation of cameras can be instructive in revealing their potential as photographic tools, it remains incomplete and does no justice, for example, to the way the GFX 100 or the K-70 perform in practice. 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 hands-on reviews by experts are important. 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.

padding

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. A score, therefore, has to be seen in close connection to the price and market introduction time 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.
