Shake Reduction (SR)
Shake Reduction (SR) on the I(-1" 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.
Additionally Saving as a RAW Image
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 by pressing the []Av button during playback.
If the image was shot using any of the following settings, the
corresponding RAW image listed is saved.
• Cross Processing RAW image without Cross Processing
• Digital Filter RAW image without filter effect
• HDR Capture RAW image with standard exposure
• Multi-exposure RAW image with Multi-exposure
The captured area (view angle) will differ between the I_-_" 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: 36x24 mm
I_-t" CMOS sensor: 23.6x15.8 mm
The focal length of a lens used with a 35 mm camera is about 1.5 times longer
than that of the/_-_". 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 I_-_".
Inversely, multiply the focal length of the lens used with the I_-t" by 1.5 to
determine the focal length for 35 mm cameras.
Example) If 300 mm lens is used with the I_-t"
300x 1.5=450
Focal length is equivalent to a 450 mm lens on a 35 mm camera.
