Have I got this right?
To use the lens disconnected as above you have to remove it from the camera while the camera is on otherwise the lens internal shutter is closed?
And we are stuck with full open aperture?

OK-- before someone else gets the same silly idea
-- I took a spare 40.5mm uv filter and smashed the glass out of it. I then took a Dmount to Q adapter and ground a little off the rim so I could then mount in in the female end of the filter ring. Presto-- a reversing ring for the 01 and 02. About 4mm depth between filter thread and mount..
But same result as Barondla-- way too close for the 01 and not much better for the 02 out at 15.
Of course it is a moot point how much extension that was because you need to know where the optical centre of the lens is.
I take it the focussing is electrical with no physical connection to the focuss ring--- So no focussing available.
So a total waste of cunning scheming
