Before Using Your Camera

• Records in the versatile JPEG format or the high quality and fully
editable RAW format. You can also select JPEG+RAW and record in
both formats. Pictures taken in RAW format can be easily processed
internally by the camera.
• Features Custom Image and White Balance which allow you to readjust
images shot in JPEG format without affecting the image quality.
• Supports the optional Battery Grip D-BG4 with vertical shutter release
button. If a battery (D-LI90) is inserted in both the camera and grip, the
battery with more power is prioritized. This enables you to get the best
camera performance for an extended period. A menu item also allows
you to prioritize a battery and use its full power before switching to the
other battery.
Shake Reduction (SR)
Shake Reduction (SR) on the Q features a PENTAX original system
which uses magnetic force to move the image sensor at high speeds,
compensating camera shake.
The camera may generate some operating noise when it is shaken, such
as when changing the composition of a picture. It is not a malfunction.
The captured area (view angle) will differ between the Q and 35 mm SLR
cameras even if the same lens is used because the format size for 35 mm film
and CMOS sensor are different.
Sizes for 35 mm film and CMOS sensor
35 mm film : 36×24 mm
Q CMOS sensor : 23.4×15.6 mm
Angles of view being equal, the focal length of a lens used with a 35 mm camera
must be approximately 1.5 times longer than that of Q. To obtain an angle
of view framing the same area, divide the focal length of the 35 mm lens by 1.5.
Example) To capture the same image as a 150 mm lens attached to a 35 mm
camera
150÷1.5=100
Use a 100 mm lens with the Q.
Inversely, multiply the focal length of the lens used with the Q by 1.5 to
determine the focal length for 35 mm cameras.
Example) If 300 mm lens is used with the Q
300×1.5=450
Focal length is equivalent to a 450 mm lens on a 35 mm camera.
