I also am looking out for a 50-150 after missing out on a second hand one that I had found got sold the day before I went to buy it!![]()
I have the original version (without OS), and it's an excellent lens. The new OS version is supposed to be even better, but is nearly twice as heavy and a lot bigger, which was enough to put me off.
Cool, I've subscribed to this thread as I was looking at these too. I have no plans to 'go full frame', despite getting the feeling that this is something everybody should be conscious of, or work towards...![]()

Yes I can't see myself going full frame any time soon either can't afford it or at least I can't afford the glass to make full frame worthwhile![]()

My point was that the 35mm won't work on that full frame body that I have no intention of buying, yet it still put me off it..![]()

what do you think of the d7k btw? I've pretty much decided this is the body I'm going to get.
