• Records images 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 simultaneously. When the file format of the last captured
image is JPEG, and its data still remains in the buffer memory, you can
additionally save the image in RAW format. RAW images can be easily
processed internally by the camera.
• Up to five setting patterns can be saved in A mode. In addition,
functions for the |/Y button and the e-dials can also be
customized, enabling speedy operation by any type of photographer.
• 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.
The captured area (view angle) will differ between the X and 35 mm SLR
cameras even if the same lens is used because the format sizes for 35 mm film
and CMOS sensor are different.
Sizes for 35 mm film and CMOS sensor
35 mm film : 36×24 mm
X CMOS sensor : 23.7×15.7 mm
The focal length of a lens used with a 35 mm camera is about 1.5 times longer
than that of the X. To shoot images with 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 X.
Inversely, multiply the focal length of the lens used with the X by 1.5 to
determine the focal length for 35 mm cameras.
Example) If 300 mm lens is used with the X
300×1.5=450
Focal length is equivalent to a 450 mm lens on a 35 mm camera.
Shake Reduction (SR)
Shake Reduction (SR) on the X features a PENTAX original
system which uses magnetic force to move the image sensor at high
speeds, compensating for camera shake.
The camera may generate some operating noise when it is shaken,
such as when changing the composition of a picture. This is normal
and not a malfunction.
