Thanks, Bob. I still have a Soligor 80-200 f4.5 which works like that, but not the Vivitar. There must either be a trick I haven't yet discovered or perhaps one has to use an extension tube?

Run it out as close as you can focus then pull the front out about 2
mm and continue closer focus?  I had something that worked like that
once. Remember to be macro focusing, you will need to get extra
extension of the lens, moving the front farther from the camera body.
Hope this helps.

Picked up a Vivitar 75-200mm f4.5 MC MACRO FOCUSING ZOOM for a song. It is
an "A" lens & works well but unfortunately has a bit of fungus inside (which
doesn't seem to affect it's performance). Is there any easy way I can get
rid of it without stripping the lens? I read on the web that the spores can
get out & "infect" other lenses so I don't know if that's a problem too.
Lastly, maybe I'm dof, but I can't figure out how to get into macro mode. It
doesn't "pop" like a similar Soligor lens.
