The listed prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The Pentax K-50 was launched in the US market at a price of $599. 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 sensor inside a digital camera is one of the key determinants 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 are more costly to manufacture and tent to lead to bigger and heavier cameras and lenses.
The Pentax K-50 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-50 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 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 adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of alternative cameras.

Many modern cameras are not only capable of taking still images, but can also record movies. The K-50 indeed provides movie recording capabilities. The highest resolution format that the K-50 can use is 1080/30p.
Beyond body and sensor, cameras can and do differ across a range of features. For example, the K-50 has an optical viewfinder that provides a field of view of 100% and a magnification of 0.61x. The tables below summarize some of the other core capabilities of the Pentax K-50 in connection with corresponding information for a sample of similar cameras.

One convenient feature of the K-50 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-50 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

While the specs-based evaluation of cameras is instructive in revealing their potential as photographic tools, it remains incomplete and does no justice, for example, to the way the K-50 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 why hands-on reviews by experts are important. The table below summarizes the assessments of some of the best known camera review sites (amateurphotographer [AP], cameralabs [CL], digitalcameraworld [DCW], dpreview [DPR], ephotozine [EPZ], photographyblog [PB]).

|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. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, and comparisons of ratings among very different cameras or across long time periods have little meaning. Also, please note that some of the review sites have changed their methodology and reporting over time.
Pentax K-50 FAQ
Below are some additional questions and answers concerning some particular features of the K-50.
What technology is the imaging sensor in the K-50 based on?
The camera is build around 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-50 with the PRIME M image processor.
What is the ISO sensitivity range of the K-50?
The camera has a native sensitivity range from ISO 100 to ISO 51200.
What is the life expectancy of the shutter in the Pentax K-50?
Pentax does not publish a shutter rating for the K-50. Yet, shutters in comparable cameras from other manufacturers are said to be good for at least 100 000 actuations. It should be noted, though, that this number represents a Mean Time before Failure. The shutter might fail earlier, or it might last longer. Anyway, in order to exhaust an expected shutter life of 100 000 shots 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 K-50?
Pentax embeds the number of shutter actuations in image metadata. You can check the number of shots that your K-50 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?
No, the Pentax K-50 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-50?
The K-50 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-50 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-50's flash sync speed is 1/180 sec.
Which battery does the K-50 use?
