Fujifilm X-H1 vs Pentax K-1
The Fujifilm X-H1 and the Pentax K-1 are two enthusiast cameras that were officially introduced, respectively, in February 2018 and February 2016. The X-H1 is a mirrorless interchangeable lens camera, while the K-1 is a DSLR. The cameras are based on an APS-C (X-H1) and a full frame (K-1) sensor. The Fujifilm has a resolution of 24 megapixels, whereas the Pentax provides 36.2 MP.
Below is an overview of the main specs of the two cameras as a starting point for the comparison.
Going beyond this snapshot of core features and characteristics, what are the differences between the Fujifilm X-H1 and the Pentax K-1? Which one should you buy? Read on to find out how these two cameras compare with respect to their body size, their imaging sensors, their shooting features, their input-output connections, and their reception by expert reviewers.
The physical size and weight of the Fujifilm X-H1 and the Pentax K-1 are illustrated 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 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 X-H1 is only available in black.
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 notably larger (11 percent) than the Fujifilm X-H1. Moreover, the K-1 is substantially heavier (50 percent) than the X-H1. 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 X-H1 gets 310 shots out of its NP-W126S battery, while the K-1 can take 760 images on a single charge of its D-LI90 power pack. The power pack in the X-H1 can be charged via the USB port, so that it is not always necessary to take the battery charger along when travelling.

Any camera decision will obviously take relative prices into account. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The K-1 was somewhat cheaper (by 5 percent) than the X-H1 at launch, but both cameras fall into the same price category. 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.
The size of the sensor inside a digital camera is one of the key determinants 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. 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 more expensive and lead to bigger and heavier cameras and lenses.
Of the two cameras under consideration, the Fujifilm X-H1 features an APS-C sensor and the Pentax K-1 a full frame sensor. The sensor area in the K-1 is 134 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.5 and 1.0. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.
In terms of underlying technology, both cameras are build around CMOS sensors.
With 36.2MP, the K-1 offers a higher resolution than the X-H1 (24MP), but the K-1 nevertheless has larger individual pixels (pixel pitch of 4.88μm versus 3.92μm for the X-H1) due to its larger sensor. However, the X-H1 is a somewhat more recent model (by 1 year and 11 months) than the K-1, and its sensor might 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 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 Pentax K-1 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the K-1 for good quality output (200 dots per inch) amounts to 36.8 x 24.6 inches or 93.5 x 62.4 cm, for very good quality (250 dpi) 29.4 x 19.6 inches or 74.8 x 49.9 cm, and for excellent quality (300 dpi) 24.5 x 16.4 inches or 62.3 x 41.6 cm. The corresponding values for the Fujifilm X-H1 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 X-H1 has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.
Unlike the X-H1, the K-1 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 X-H1 has a native sensitivity range from ISO 200 to ISO 12800, which can be extended to ISO 100-51200. The corresponding ISO settings for the Pentax K-1 are ISO 100 to ISO 204800 (no boost).
Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. This service assesses and scores the color depth ("DXO Portrait"), dynamic range ("DXO Landscape"), and low-light sensitivity ("DXO Sports") of camera sensors, and also publishes an overall camera score. The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

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 X-H1 provides a higher video resolution than the K-1. It can shoot video footage at 4K/30p, while the Pentax is limited to 1080/60i.
Apart from body and sensor, cameras can and do differ across a variety of features. For example, the X-H1 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 X-H1 has a higher magnification than the one of the K-1 (0.75x 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 X-H1, the Pentax K-1, and comparable cameras.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The X-H1 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 X-H1 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 X-H1 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 X-H1 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 X-H1 supports UHS-II cards (on both slots), while the K-1 can use UHS-I cards.
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. The table below provides an overview of the connectivity of the Fujifilm X-H1 and Pentax K-1 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the K-1 has a headphone jack, which makes it possible to attach external headphones and monitor the quality of sound during the recording process. The X-H1 lacks such a headphone port.
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 X-H1 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 two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Fujifilm and Pentax websites.
So what is the bottom line? Is there a clear favorite between the Fujifilm X-H1 and the Pentax K-1? Which camera is better? A synthesis of the relative strong points of each of the models is listed below.

If the count of individual advantages (bullet points above) is taken as a guide, the X-H1 comes out slightly ahead of the K-1 (13 : 12 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 before making a decision 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.
How about other alternatives? Do the specifications of the Fujifilm X-H1 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 specs-based evaluation of cameras can be instructive in revealing their potential as photographic tools, it says little about, for example, the shooting experience and imaging performance of the X-H1 and the K-1 in practical situations. 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.
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 (cameralabs, dpreview, ephotozine, imaging-resource, and photographyblog). 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.

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. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, 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.
