I've asked this quest but haven't gotten a straight answer yet. I have a 1270 nice little unit . Thinking of upgrading but also read about the lens flapping mod, does this make that much of a difference in sharpness? Would it be compatible with lets say electromagnetic focus? If so would this be the mod to do? Which would keep me from upgrading . Then if the mod is so good why then change units? would like to hear from someone thats done the mod, and see what they have to say.
