Does anyone have experiences (good or bad) with this vintage? I bought one to
compliment my 3.5 Zuiko for concert shots. At <$40
including a hard case, why not? Did Tamron ever make an "SP" 135? This is a
late vintage ("BBAR" coatings) but it's not an "SP"
model and it's only a 4 element design! Yikes!
3.5 is 2/3 stop slower than 2.8, right? Is 2.5 another 1/3 faster still or
something less? My real question is when I switch from
the 3.5 to the 2.5, is it a full stop's more light? The Zuiko is just barely
sharp enough to use wide open but I'm not expecting
miracles from a fast, 4 element design. "It's not in the numbers" as Captain
Furillo would say.
Besides the Series1 f/2.3, are there other speed demons in OM mount that have
some claim to image quality? (Besides the Tamron
80-200 f/2.8, and Tokina 80-200 f/2.8)
Can I interest anyone in an Adaptall2 mount for a Konica? I didn't think so.
:)
People, let's be CAREFUL out there.
