"Nothing notable is ever accomplished by a reasonable person."

I think RA Heinlein wrote that, so it must be true.

I loved that David Carradine show---btw, nobody woulld have been caught dead using words like these in that show--no enlightened being, that is--no way Rico.

krp Thanks for your replies everyone. Jewel I usually take a ton of 30 second pictures of the stars and put them together to avoid DFS, so that's why a faster lens would be beneficial. I haven't heard much about the that 24-135 lens. I think I would rather have wider than longer though.
Kevin--one more thing, the 24-135 is built like a tank, even better than the 17-50--it has a nicely dampened focus ring too--The 17-50 is built better than I need though.

Can't get better value for money than that. Enjoy the lens.

LBA we must; all others eat dust.

Well I got my lens in 4 days with free shipping from Japan. It's used but it looks completely new. I'm noticing a ff/bf problem. I'm wondering/hoping that it's a problem with my K-x because then I can fix it myself in debug menu. This is my fastest af lens and I haven't taken that many close up shots before so maybe I'm just noticing it more now with the Tamron having a shallower dof? Testing my kit lens it does seem to front focus a little at the long end and back focus some on the wide end. It's the same with the Tamron but it's more pronounced presumably because of less dof. Does this sound possible or did I test it wrong? I shot a ruler on a table at a 45 degree angle on a tripod with mirror lockup and a remote. I also made sure the focus point was aligned exactly at 15 cm on the ruler. I really want to keep this lens. The ebay shop has had great service and they have a 7 day return policy that says they will exchange it if the buyer pays return shipping. If I try the debug menu is it risky?
Thanks for your help.

I think I may have fixed with an adjustment of +60 in debug mode. I'll have to do more testing tomorrow to be sure.
