Wobble on F* 300 f4.5

2005-03-16 Thread jtainter
I know several of you have this lens. Could you let me know how much wobble there is in the barrel? The wobble will be centered under the autofocus/manual focus shift ring. Does wobble seem to affect image sharpness? I just returned one that had so much wobble here that I thought the lens had

Could you snap a pic to indicate where exact the wobble is? Is the whole lens barrel loose, or you just hearing the sound inside? - Alan, I no longer have the lens. I returned it. If you go to Boz's site, there is a photo of the lens. Be sure to pull up the F version. Immediately
