Pentax K-1 vs Sony RX10 IV
The Pentax K-1 and the Sony Cyber-shot DSC-RX10 IV are two enthusiast cameras that were announced, respectively, in February 2016 and September 2017. The K-1 is a DSLR, while the RX10 IV is a fixed lens compact. The cameras are based on a full frame (K-1) and an one-inch (RX10 IV) sensor. The Pentax has a resolution of 36.2 megapixels, whereas the Sony provides 20 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 Pentax K-1 and the Sony Cyber-shot DSC-RX10 IV? 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 Pentax K-1 and the Sony RX10 IV 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 dimensions are rounded to the nearest millimeter.
The K-1 can be obtained in two different colors (black, silver), while the RX10 IV 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 Sony RX10 IV is notably smaller (17 percent) than the Pentax K-1. 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 and possibly misleading, as the RX10 IV has a lens built in, whereas the K-1 is an interchangeable lens camera that requires a separate lens. Attaching the latter will add extra weight and bulk to the setup.
Concerning battery life, the K-1 gets 760 shots out of its D-LI90 battery, while the RX10 IV can take 400 images on a single charge of its NP-FW50 power pack. The power pack in the RX10 IV can be charged via the USB port, which can be very convenient when travelling.
The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones.

Any camera decision will naturally be influenced heavily by the price. The manufacturer’s suggested retail prices give an idea on the placement of the camera in the maker’s lineup and the broader market. The RX10 IV was launched at a lower price than the K-1, despite having a lens built in. 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 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 tend to have larger individual pixels that provide better low-light sensitivity, wider dynamic range, and richer color-depth than smaller pixel-units 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-1 features a full frame sensor and the Sony RX10 IV an one-inch sensor. The sensor area in the RX10 IV is 87 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.0 and 2.7. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.
With 36.2MP, the K-1 offers a higher resolution than the RX10 IV (20MP), but the K-1 nevertheless has larger individual pixels (pixel pitch of 4.88μm versus 2.41μm for the RX10 IV) due to its larger sensor. However, the RX10 IV is a somewhat more recent model (by 1 year and 6 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 pixels. Coming back to sensor resolution, it should be mentioned that the K-1 has no anti-alias filter installed, so that it can capture all the detail its 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 Sony RX10 IV are 27.4 x 18.2 inches or 69.5 x 46.3 cm for good quality, 21.9 x 14.6 inches or 55.6 x 37.1 cm for very good quality, and 18.2 x 12.2 inches or 46.3 x 30.9 cm for excellent quality prints.
The RX10 IV has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.
Unlike the RX10 IV, 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 Pentax K-1 has a native sensitivity range from ISO 100 to ISO 204800. The corresponding ISO settings for the Sony Cyber-shot DSC-RX10 IV are ISO 100 to ISO 12800, with the possibility to increase the ISO range to 64-25600.
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 following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.

Many modern cameras are not only capable of taking still images, but also of capturing video footage. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the RX10 IV provides a better video resolution than the K-1. It can shoot movie footage at 4K/30p, while the Pentax is limited to 1080/60i.
Beyond body and sensor, cameras can and do differ across a range of features. For example, the RX10 IV has an electronic viewfinder (2359k 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%), as well as the same magnification (0.70x). The adjacent table lists some of the other core features of the Pentax K-1 and Sony RX10 IV along with similar information for a selection of comparators.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The RX10 IV 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 RX10 IV 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-1 has 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.
The K-1 writes its imaging data to SDXC cards, while the RX10 IV uses SDXC or Memory Stick PRO Duo cards. The K-1 features dual card slots, which can be very useful in case a memory card fails. In contrast, the RX10 IV only has one slot. Both cameras can use UHS-I cards, which provide for Ultra High Speed data transfer of up to 104 MB/s.
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 Pentax K-1 and Sony Cyber-shot DSC-RX10 IV and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Studio photographers will appreciate that the Pentax K-1 (unlike the RX10 IV) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.
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 RX10 IV is a recent model that features in the current product line-up of Sony. 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 Pentax and Sony websites.
So what is the bottom line? Which of the two cameras – the Pentax K-1 or the Sony RX10 IV – has the upper hand? Is one clearly better than the other? The listing below highlights the relative strengths of the two models.

If the number of relative strengths (bullet points above) is taken as a guide, the K-1 emerges as the winner of the contest (18 : 15 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.
How about other alternatives? Do the specifications of the Pentax K-1 and the Sony RX10 IV place the cameras among the top in their class? Find out in the latest Best DSLR Camera and Best Superzoom 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 K-1 or the RX10 IV perform in practice. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased.
This is where reviews by experts come in. The following table reports the overall ratings of the cameras as published by some of the major camera review sites (amateurphotographer [AP], cameralabs [CL], 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.

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. 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, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
