The listed prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The Pentax K-5 II 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 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.
The Pentax K-5 II 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 K-5 II among the medium-sized sensor cameras that aim to strike a balance between image quality and portability.
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 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 K-5 II indeed provides movie recording capabilities. The highest resolution format that the K-5 II can use is 1080/25p.
Apart from body and sensor, cameras can and do differ across a range of features. For example, the K-5 II has an optical viewfinder that provides a field of view of 100% and a magnification of 0.61x. The adjacent tables list some of the other core features of the Pentax K-5 II along with similar information for a selection of comparators.

One convenient feature of the K-5 II 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 K-5 II and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the K-5 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 the spec-sheets of cameras can offer a general idea of their imaging potential, it says nothing about, for example, the handling, responsiveness, and overall imaging quality of the K-5 II in practical situations. 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 why hands-on reviews by experts are important. The following table reports the overall rankings of the cameras as published by some of the major camera review sites (amateurphotographer [AP], cameralabs [CL], dpreview [DPR], ephotozine [EPZ], photographyblog [PB]).

The above review scores should be interpreted with care, 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 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.
Pentax K-5 II FAQ
Below are some additional questions and answers concerning some particular features of the K-5 II.
What type of imaging sensor is used in the K-5 II?
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 K-5 II with the PRIME II image processor.
What is the ISO sensitivity range of the K-5 II?
The camera has a native sensitivity range from ISO 100 to ISO 12800, which can be extended to ISO 80-51200.
What is the life expectancy of the shutter in the Pentax K-5 II?
Pentax mentions a shutter rating of 100 000 actuations for the K-5 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-5 II over, say, three years, one would have to take about 100 pictures each and every day.
Do I need to purchase an external camera trigger to shoot time-lapse sequences?
No, the Pentax K-5 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.
Does the Pentax K-5 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-5 II's flash sync speed is 1/180 sec.
Which battery does the K-5 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-5 II?
Yes, Pentax offers the D-BG4 as an optional accessory to facilitate shooting in portrait orientation and to provide additional battery power.
