(3) About Digital Camera mount and Film Camera mount
This lens has been adjusted at the factory so that it can be used with a digital camera.
The flange focal length, distance from the flange (mounting surface) of the camera to the focal plane, differs
between a digital camera (including a compensa-tion prism) and a film camera (not including a compen-sation
prism).
Therefore, if the lens is installed onto a film camera as it is, the original optical performance is not derived.
To use the lens with a film camera, we recommend using a
"mount for film camera" (optional accessory, equipped with a
compensation prism).
Note 1. The adjustment matched to an individual lens is
required for the "mount for film camera," there-
fore the lens has to be returned to the factory.
Note 2. The mount for film camera and the mount for
digital camera can be exchanged by removing
the eight screws on the mount part.
