Todd & Tanya,
Yes I am confused too. As I said in an earlier post I used to own a Tamron
135 2.5 close focus (Stolen 3 yrs ago). But IIRC mine had an A setting on
the aperture ring. And I thought thats what the A in PKA mount stood for.
Not so in this case it seems.
OK so the original (Whoosh) should still apply. Trouble is it's 2am here
now (UK) and my brain is definitely starting to hurt. I may try to apply
Erwins rules to your specifics - 400 asa film & f2.5 max aperture if I ever
get my clever head back but it wont work at present. Going to bed now.
Peter
