Can some of you veterans out there share with me some wisdom when purchasing a new lens from any retail outlet?
Do u test several copies of the same lens to get the sharpest copy? What kind of tests do you perform?
Will the retailers allow this?
Any other stuff to look out for before taking the plunge?
