A3 F-MOUNT ADAPTER
A3.1 PCO F-MOUNT ADAPTER
PCO's proprietary F-mount adapter for lenses
with automatic diaphragm. Sets manually the
lens aperture by turning the ring on the
adapter.
F-mount lenses
without automatic
diaphragm can be
fastened to the
camera's mount but
the
aperture not
changed.
Adjust Back Focal Length
To adjust the back focal length (e.g. you
cannot focus to infinity or to the minimum
object distance of your lens), proceed as
follows:
Set the focus of your lens to infinity. Look at
an object in infinity and generate a sharp
image by turning the adapter. Use the
rearmost ring to fix the setting.
Matching Lenses with Automatic Diaphragm

is only electronic).
