Shake Reduction (SR)
Shake Reduction (SR) on the e/y 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.
Help Function
The guides displayed for the e/y help function have been
designed for use in combination with a DA or DA L lens.
When using another lens with the aperture ring not set to the s (Auto)
position, some of the guides displayed may not match the actual
conditions.
The captured area (view angle) will differ between the e/y and 35
mm SLR cameras even if the same lens is used because the format size for 35
mm film and CCD are different.
Sizes for 35 mm film and CCD
35 mm film : 36×24 mm
e/y CCD : 23.5×15.7 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
e
/
y
. 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 e/y.
Inversely, multiply the focal length of the lens used with the e/y by
1.5 to determine the focal length for 35 mm cameras.
Example) If 300 mm lens is used with the e/y
300×1.5=450
Focal length is equivalent to a 450 mm lens on a 35 mm camera.
