Hey all, just changed over the backend after 15 years I figured time to give it a bit of an update, its probably gonna be a bit weird for most of you and i am sure there is a few bugs to work out but it should kinda work the same as before... hopefully :)
Hello Pat
The front of the lenses moves in and out with focus but does not turn. It is 80mm front and the front shade can be unscrewed and they have diopters that screw in place of the shade and they are also 80mm.
