I'm considering getting either a Canon 100-400 or the Sigma 150-500.
I would like to try a few first though, and am wondering if anyone has experience with good shops around Boston to go to when you want to take a few test shots.
Ideally i would like to take a couple shots from several copies of each lens. Will they laugh at me and tell me to take a hike? I know they don't mind a few shots to test a lens. But can i try 3 100-400 and make a note of the serial numbers, then come back after pixel peeping at home?
I would think they might be eager to sell the lens, but not so eager to have me handling them all.
So... any comments on this plan? Places to go? Suggestions for smooth talking a clerk?
