Finally ready to purchase a Tokina 11-16. I have decided on this over the Canon mainly because I do mostly video for now and the 2.8 will be very helpful. My question is should I buy a used Version 1 or go for a new Version 2 copy. Apparently it has better coating to decrease the flare issue but I have never had a chance to try the 11-16 in 'flare-ey' situations to even tell if it would be an issue for me. Has anyone tried both? Other than flare is there any other reason to go with new? I'm on a budget so I'm fine with the used V1 copy, but If the V2's usability warrant the price then I'm all for that as well..
