The listed prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The Pentax K-5 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. 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-5 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 among the medium-sized sensor cameras that aim to strike a balance between image quality and portability.
For most cameras, data on sensor performance has been reported by DXO Mark. 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 alternatives.

It is notable that the K-5 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.
Further information on the features and operation of the K-5 can be found in the free online Pentax K-5 Manual or on the Pentax support site.
Expert reviews
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-5 handle or perform in practice. 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 why expert reviews are important. The adjacent table relays the overall verdicts of several of the most popular camera review sites (amateurphotographer [AP], cameralabs [CL], digitalcameraworld [DCW], dpreview [DPR], ephotozine [EPZ], photographyblog [PB]).

The review scores listed above should be treated 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 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 FAQ
Below are some additional questions and answers concerning some particular features of the K-5.
What type of imaging sensor is used in the Pentax K-5?
The camera has a CMOS (Complementary Metal–Oxide–Semiconductor) sensor at its core.
Which image processing chip is used in the Pentax K-5 to convert the raw signal into an image file and perform noise reduction and image sharpening?
Pentax equipped the K-5 with the PRIME II image processor.
What is the ISO sensitivity range of the Pentax K-5?
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?
Pentax mentions a shutter rating of 100 000 actuations for the K-5. 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 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 K-5?
Pentax embeds the number of shutter actuations in image metadata. You can check the number of shots that your K-5 has taken up to now by uploading a recent image to the free online shutter count finder app.
Do I need to purchase an external camera trigger to shoot time-lapse sequences with the Pentax K-5?
No, the Pentax K-5 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 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 the Pentax K-5 for flash photography?
The K-5's flash sync speed is 1/180 sec.
Which battery does the Pentax K-5 use?
The camera gets its power from the Pentax D-LI90 (here at amazon), which is a rechargeable Lithium-Ion power pack.
Is there a vertical grip available for the Pentax K-5?
Yes, Pentax offers the D-BG4 as an optional accessory to facilitate shooting in portrait orientation and to provide additional battery power.
