I tried to send you a pm a couple of days ago but probably screwed something up. The info you told me about was great. I figured what the IS and USM stood for but couldn't find out what the S stood for. My other question was what do you think of buying any of these used and what would you consider being a good price? Do you know of any good web sites that mite help me out with my decisions on buying and using my future hobby?
I tore my rotator cuff in my right shoulder at work recently and the MRI showed it was not repairable and I'm looking at a replacement shoulder down the road, the farther down down the road the better. So it looks like the only thing I'll be shooting this season will be a camera. Do you know any body who switched from shooting right handed to left?
