well i tried the new lens , and i think its much better . idealy i should be using a macro lens though caus i cant get as close as i would like. i still had a bit of trouble getting the eye in focus . it almost looks like it focuses a little closser than where the red dot lights up. if i focus on the eye , thenose is sharp . in this pic i focused slightly behind the eye. just my luck , there is no focus adjustment on the t4i lol.
