I don't remember exactly but you have to set them either to 70mm or
210mm, (I can't remember which), press the white locking tabs and turn
the collar to the right, with the lens pointed tword the target, IIRC.

Someone just asked me a question about Version 1 (Kiron) of the Vivitar
70-210 Series 1 and I can't answer it because I only have version 3
(Komine). They want to know how you put it into "macro" mode.
Perhaps I should add this to my Vivitar page
