Subject: [OM] macro doubler
> I very gingerly attempted to mate a 90/2 macro to a 2X-A and discovered
that the 90/2 has a tiny metal tab that seems to have been specifically
designed to prevent use of the lens with the 2X-A. I infer the reason for
that is that if the lens were to be focused at infinity, the rear element
would come into contact with parts in the 2X-A, a potential disaster. (I
think older lenses like the 55/1.2 do not have this tab feature).

> I very gingerly tested the 90/2 with a Tokina doubler and it seems to work
without any contact occurring. I think it yields a 180/4 1:1 macro.
