Confirmation of SR mechanism (When use different type of focal length)
The shutter speed of prevention for shaking is calculate with [1 / focal length of the lens]
For instance, if the focal length is 200mm: 1/ (200 x 1.5) = 1/300
* Size of picture for digital camera is 23.5 x 15.7mm and it is about 1.5 times when converting it into the
focal length of 35milli-size camera.
① Calculate the shutter speed of prevention for shaking as above.
For instance, if the focal length is 200mm: 1/ (200 x 1.5) = 1/300
② Converts above shutter speed to two step down
1/300 1/150 1/75 It is equal to approx 1/80
③ Set Tv 80 (or TV 90 and 1/2 EV step)
④ Follow the procedure of 27－6, ④～⑧
[Caution] The effect of the shake reduction is influenced by the focal length of the lens and the object
distance
and effect might not become visible in the short distance (D-FA50mm Macro 0.4m), also an enough effect
might not become visible at the low temperature.
