Hi there,
A couple of my OCT 18 lenses I'm currently using on my GH2 need a bit of TLC, namely - the aperture ring on the 35mm F2 (OKC 11 35 1) is stuck wide open and will no longer turn (focus still works) and my 28 F2 (OKC 4 28 2) when mounted on the ciecio7 OCT18 adaptor ( Adaptor ) is incredibly stiff to focus although when uncoupled from the mount, the focus ring performs very smoothly.
Any help would be most gratefully welcome!
Many thanks,
Lee
