and despite yet another wordy Don rant...you fail to answer the crux of the issue at hand. answer the question....
what exactly are you asking for ? every manufacturer to stock every retailer with all of their premium glass ?
as for trying out the 70-200 lens. thats yet another arguement devoid of logic. the lens' i have bought are all sealed/ if i get an unsealed box i can sure as hell tell you its going back. i'm buying NEW, not a display model where every man and his dog can handle it, play with it, shoot with it, get dust in it and put their grubby mits all over it. bugger that for a joke.
so by your logic, the retailer would have to say to you...FINE Don, you PAY for the lens before i break the seal and if its defective then i'll get you another one...but if you wanna handle it, you BUY it.
you'll have to do alot better than type out such nonsense to make your point with me.
