The listed prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The Pentax KP was launched in the US market at a price of $1,099. 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. 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 tent to lead to bigger and heavier cameras and lenses.
The Pentax KP features an APS-C sensor and has a format factor (sometimes also referred to as "crop factor") of 1.5. Within the spectrum of camera sensors, this places the Pentax KP among the medium-sized sensor cameras that aim to strike a balance between image quality and portability.
Consistent information on actual sensor performance is available from DXO Mark for most cameras. This service is based on lab testing and assigns an overall score to each camera sensor, as well as ratings for dynamic range ("DXO Landscape"), color depth ("DXO Portrait"), and low-light sensitivity ("DXO Sports"). 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 can also record movies. The KP indeed provides movie recording capabilities. The highest resolution format that the KP can use is 1080/60i.
Apart from body and sensor, cameras can and do differ across a variety of features. For example, the KP has an optical viewfinder that provides a field of view of 100% and a magnification of 0.63x. The following tables report on some other key feature differences and similarities of the Pentax KP and comparable cameras.

One convenient feature of the KP is the presence of an on-board flash. While this built-in flash is not very powerful, it can at times be useful as a fill-in light to brighten deep shadow areas.
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 KP and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the KP 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 partial and cannot reveal, for example, the handling experience and imaging performance when actually working with the KP. 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 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).
The review scores listed above should be treated 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. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
Pentax KP FAQ
Below are some additional questions and answers concerning some particular features of the KP.
What is the technology behind the imaging sensor in the KP?
The camera has a CMOS (Complementary Metal–Oxide–Semiconductor) sensor at its core.
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 KP with the PRIME IV image processor.
What is the ISO sensitivity range of the KP?
The camera has a native sensitivity range from ISO 100 to ISO 819200.
What is the life expectancy of the shutter in the Pentax KP?
Pentax mentions a shutter rating of 100 000 actuations for the KP. 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 KP over, say, three years, one would have to take about 100 pictures each and every day.
How do I find the shutter count on my Pentax KP?
Pentax embeds the number of shutter actuations in image metadata. You can check the number of shots that your KP has taken up to now by uploading a recent image to the online shutter count app.
Is completely silent shooting possible with the Pentax KP?
The camera has an electronic shutter option, so that it is indeed feasible to capture images without any shutter noise.
Do I need to purchase an external camera trigger to shoot time-lapse sequences?
No, the Pentax KP 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 KP?
The KP 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 KP 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 KP's flash sync speed is 1/180 sec.
Does the Pentax KP 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 KP use?
The camera gets its power from the D-LI109 (here at amazon), which is a rechargeable Lithium-Ion power pack.
Is there a vertical grip available for the KP?
Yes, Pentax offers the D-BG7 as an optional accessory to facilitate shooting in portrait orientation and to provide additional battery power.
