Datasheet

When the central sensor is selected as a select point, the eight
neighboring sensors are used to assist the tracking. The activated
sensors are highlighted in pink on the status screen.
The sensor point shifts automatically (as does the superimposed
select point), as the subject moves away. (Note: Only the in-focus
point is displayed on the actual status screen.)
Thanks to the incorporation of a high-quality glass pentaprism, the K-50’s optical
viewfinder offers an approximately 92% magnification to assure a large, clear view of the
subject — even with the fast-moving subjects found in sports. In addition, the
viewfinder offers a nearly 100% field of view for quick, accurate image composition.
The K-50’s advanced metering system makes extremely accurate measurement of
illumination levels across the image field. By assessing such factors as the camera’s
alignment (horizontal or vertical), the subject’s distance and position, and the lens’s
magnification, it then calculates the optimum exposure level for a given scene, assuring
the best balance between subject and background, highlights and shadows. The K-50
also offers the option of center-weighted and spot metering.
With its top speed of 1/6000 second, the K-50’s high-speed shutter lets you freeze the
split-second action of fast-moving subjects, such as athletes and pets. When shooting in
bright sunshine, it also lets you open up an aperture to intentionally throw the
background out of focus without overexposing the subject.
The surface of the CMOS image sensor is treated with PENTAX-original SP (Special
Protect) coating to minimize the clinging of dust. Any dust that does adhere to the
surface is then effectively removed by the DR (Dust Removal) mechanism, which shakes
the dust off the sensor using high-speed vibration to prevent any annoying dust spot
from appearing on captured images.
Newly added to the WR series, the DA L 18-55mm F3.5-5.6AL WR and DA L 50-200mm
F4-5.6ED WR lenses feature a simplified weather-resistant construction to repel a light
splash of water. A selection of the DA
H
AW series featuring a more rugged
weather-resistant, dustproof construction is also available. By coupling the K-50 with any
of these lenses, you can create a highly dependable, all-weather digital imaging system.
In addition to the standard rechargeable lithium-ion battery, the K-50 can also be
powered by four AA-size batteries using the optional battery holder. Even when the
standard battery runs out of charge, you can easily replace it with easy-to-obtain
AA-size batteries and resume shooting without any delay.
With its 11 sensor points, the K-50’s AF system lets you compose the image exactly the
way you like it. It features nine cross-type sensors in the middle for accurate, unfailing
detection of the subject.
The K-50 features the state-of-the-art SAFOX IX i+ as its AF module. It assures
extra-accurate autofocusing by minimizing chromatic aberrations within the
module with the use of a refraction lens. Its light source sensor also
compensates for the minute focusing errors caused by the different
wavelengths of various sources. Because of this, the K-50 captures the subject
in sharp, crisp focus, even under artificial light sources.
When photographing a moving subject in the AF.C (Continuous) mode, this function
keeps tracking the subject even when it moves away from a pre-assigned select point
by assessing the distance data collected by neighboring focus sensors. This prevents
erroneous focusing on the background.

The K-50’s burst shooting mode captures a maximum of six images in a single second.*
Whether it’s composition, focus or expression, this mode gives you a better chance of
capturing the best shot of a moving subject within a series of recorded images.
The SP coating applied to the sensor (low-pass filter) prevents
adhesion of foreign substances.
The SR mechanism’s vertical vibration
