Don't forget that the little filters that screw onto the back element of the lens are part of the optical formula of the lens, so if you can't focus to infinity, the little clear (I assume it's a skylight or UV) filter may not be on. I got one of these suckers last year (and I love it!): http://photo.net/photodb/photo?photo_id=3410615&size=lg http://photo.net/photodb/photo?photo_id=3393035&size=lg http://photo.net/photodb/photo?photo_id=3130444&size=lg but I did notice that I couldn't focus to infinity when I first got it - I had taken off the clear filter, but I figured it was just a bad sample or a cheap lens or something, and thought that as long as I stopped down, it wouldn't be a real problem. Sharpness is not my Holy Grail anyways <LOL>. Then someone on this list (forget who) told me about the filter thing, I put it on, and voila, problem solved! I'm not saying that's why yours couldn't focus to infinity, and maybe you already know all of this, but I'm letting you know just in case, or possibly for the benefit of others with the lens. cheers, frank -- "Sharpness is a bourgeois concept." -Henri Cartier-Bresson
