Just picked one of these up from my local camera shop for $359. The manager threw in a free Hoya 67MM HMC UV(0) filter which I thought was cool. I checked B&H and they have it for $29.99 on their site. I have a filter for my 18-200 also but I have never used it so maybe I put them on both of my Tamron lenses. Just thought I would see what people thought of the lense. I wish I could afford the beast but its not in my budget at this point in time. Any suggestions to see if I have a sharp copy?
