Just wondering what is the difference between the recently mentioned
Vivitar 90mm/2.8 someone bought from eBay and the
Vivitar 90mm/2.5 macro, series 1 in Gary's lens_test page ?
more/less plastic, different filter size (what does the 2.5 has ?)
is only the 2.5 a macro version, and what might a 2.5 be worth
and is the something like a package 90/2.5 and some kind
of a converter/tube/what-so-ever once sold from Vivitar ?
