For only R1000 ($100) I got 2 ME supers, a P30, a K70 & a RICOH KR5 super all with their kit lenses plus Tokina M & Vivitar A 80-200mm lenses, an SMC Pentax M 28mm f2.8, Sunactinon A & Sigma A 28mm f2.8's, a Fujifilm S3000 digital, 2 large FOTIMA shoulder type gadget bags, a FOTIMA pouch camera bag plus a host of small odds & ends. I'll keep what I want & should realise some profit selling the balance individually. Perhaps I can find a better 80-200mm? I have already swapped the softish SMC Pentax A zoom from the P30 for an SMC Takumar 50mm f1.4.

If it was manufactured before sometime the mid 90's the first two digits
being 42 indicate that it was made by Bauer.  Now I always thought that
Bauer was a third party lens seller who bought their products from
someone else, I could be wrong about that.  By the way Mark Roberts has
the Vivitar serial number ID chart on his Vivitar Series 1 web page:
<http://www.robertstech.com/vivitar.htm#serialno> I saved off a copy
from the Third party Lens Megasite, but Mark's site is always up.

I haven't got a good solution to fungus, even if you were able to
disassemble the lens to get to it.  There was a thread some time ago,
(several years ago IIRC), on the PDML where someone, I forget who now,
cleaned the fungus from a lens with saliva, which removed the fungus
though the actual glass surface of the element had been etched.

It seems to me that you're going to a lot of effort for a 10 buck lens,
on the other hand if you enjoy doing it why not.

These things are not that common over here. R100 is about $10, so not too much. The lens serial no. is 42027419 - perhaps you can identify the manufacturer from that? Finally, you are right - it simply close focus, marked as 1.5x. Something about the fungus perhaps?

Also if you paid more than $10 bucks for it you were taken.  You can get
a pristine copy of one of those Vivitar f4, f4.5 maximum aperture zooms
for between $25 - $35, even in A mount. They were generally well built,
but not the best optically.  In fact I think I'd rather have the later
Cosina made manual focus Series one lenses that seem to be generally
dismissed, unless the thing was literally given to me.

Vivitar sold a number of 70~75mm - 200~210mm lenses made by a number of manufactures, it would help to know which particular one you were talking about. It could be that "Macro" just means close focus, (approximately 1:4 magnification), at it's maximum focal length.

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.
