The listed prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The Pentax K-1 II was launched in the US market at a price of $1,999. 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 with a 35mm slide
The imaging sensor is at the core of digital cameras and its size is one of the main determining factors 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 are more costly to manufacture and tent to lead to bigger and heavier cameras and lenses.
The Pentax K-1 II features a full frame sensor and has a format factor (sometimes also referred to as "crop factor") of 1.0. Within the spectrum of camera sensors, this places the Pentax K-1 II among the large-sensor cameras that aim for top notch image quality.
Consistent information on actual sensor performance is available from DXO Mark for most cameras. 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 table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

Many modern cameras are not only capable of taking still images, but can also record movies. The K-1 II indeed provides movie recording capabilities. The highest resolution format that the K-1 II can use is 1080/60i.
Beyond body and sensor, cameras can and do differ across a range of features. For example, the K-1 II has an optical viewfinder that provides a field of view of 100% and a magnification of 0.70x. The tables below summarize some of the other core capabilities of the Pentax K-1 II in connection with corresponding information for a sample of similar cameras.

One useful feature of the K-1 II is a presence of 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.
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 II and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the K-1 II has a microphone port. Such an external microphone input can help to substantially improve the quality of audio recordings when a good external microphone is used.
While the comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it remains incomplete and does no justice, for example, to the way the K-1 II handle or 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 rankings of the cameras as published by some of the major camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, photographyblog).

|Notes: (+ +) highly recommended; (+) recommended; (o) reviewed; (-) not available.|
The above review scores should be interpreted with care, though. The assessments were made in relation to similar cameras of the same technological generation. Hence, a score should always be seen in the context of the camera's market launch date and its price, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, please note that some of the review sites have changed their methodology and reporting over time.
Pentax K-1 II FAQ
Below are some additional questions and answers concerning some particular features of the K-1 II.
What technology is the imaging sensor in the K-1 II based on?
The camera features a CMOS (Complementary Metal–Oxide–Semiconductor) sensor.
Which image processing chip is used to convert the raw signal into an image file and perform noise reduction and image sharpening?
Pentax equipped the K-1 II with the PRIME IV image processor.
What is the ISO sensitivity range of the K-1 II?
The camera has a native sensitivity range from ISO 100 to ISO 819200.
What is the life expectancy of the shutter in the Pentax K-1 II?
Pentax mentions a shutter rating of 300 000 actuations for the K-1 II. This number represents a Mean Time before Failure, that is an average value. The shutter might fail earlier, or it might last longer. Anyway, in order to exhaust the expected shutter life of the K-1 II over, say, three years, one would have to take about 300 pictures each and every day.
How do I find the shutter count on my Pentax K-1 II?
Pentax embeds the number of shutter actuations in image metadata. You can check the number of shots that your K-1 II has taken up to now by uploading a recent image to the online shutter count app.
Do I need to purchase an external camera trigger to shoot time-lapse sequences?
No, the Pentax K-1 II has an intervalometer built-in, so that low frequency shooting (for example, flower blooming, sunset, moon rise) can be undertaken without the need to purchase a separate external intervalometer and related software.
Is it difficult to use manual focus lenses with the Pentax K-1 II?
The K-1 II offers focus peaking as a manual focus aid. This feature works by placing a colored highlight on in-focus zones within the image.
Does the Pentax K-1 II feature an autofocus assist light?
Yes, the camera has a lamp built-in that can illuminate the subject and improve autofocus in low-light settings.
What is the fastest shutter speed that can be used with flash?
The K-1 II's flash sync speed is 1/200 sec.
Does the Pentax K-1 II support the Ultra High Speed (UHS) bus interface for SD cards?
Yes, the camera can indeed use UHS-I cards (data transfer speed of up to 104 MB/s).
Which battery does the K-1 II use?
The camera gets its power from the D-LI90 (here at amazon), which is a rechargeable Lithium-Ion power pack.
Is there a vertical grip available for the K-1 II?
Yes, Pentax offers the D-BG6 as an optional accessory to facilitate shooting in portrait orientation and to provide additional battery power.
Does the Pentax K-1 II support geotagging?
The K-1 II has a built-in GPS (Global Positioning System) module and can embed location information in the EXIF data of the captured image.
