I'm still not sure I'm with you Dan. Past infinity? Surely not - we'll
have someone chiming in with Buzz Lightyear comments if we ain't careful!
Perhaps what you are seeing is the ability to bring the lens into focus on
something in the distance, and then go out of focus again - but that would
be because "in the distance" actually isn't at infinity. That's a
phenomenon I experienced when first using a 500mm mirror lens - it's as if
infinity has syuddenly jumped back a mile or ten. But not a 'fault' with
either lens or camera.

Subject: RE: [OM] Focusing Screens
What focus screen are you using?
Dan
I think its fine, just getting the right screen I think.
It will go just a bit past infinity in focus, after reaching it, I can still
go a little more noticing the focus screen split image shift.
Common for Tamrons?
Just took some pictures but maybe I need to get use to it because it sure is
sweet and handy lens.
Seems that the lens is critical it focus much like a macro that can cause
everything around it to be out of focus quickly.
That must be how it achieves that out of focus look around a portrait so
well?

I borrowed a 180/2.5 that wouldn't reach infinity. Perhaps it's a common
problem with the lenses?
Skip
I'll chime in. It's my 180 that Skip borrowed and found unable to focus to
infinity. After Skip alerted me to the problem, I sent it off to Tamron,
who said the focusing helicoid had been damaged and needed to be replaced.
I had it done (it did cost a few), but the lens works fine now. I never
really checked infinity focus on it before because I use it more as a long
macro lens.
So maybe it is a problem unique to this lens. Its worth fixing, though.
Takes great images.
Best,
