I have used the 80-200 f/2.8 Nikkor in the past. I have NEVER noticed any halo or light falloff of any kind. Perhaps it is there, but in the pictures I have taken it is simply not a factor in the quality of the photo. Perhaps, the next time I have access to this lens (I sold mine a while back) I will take a test shot of the sky just out of curiousity. But anybody who eschews this lens for that reason, really is being misled. <Well, well... why am I not surprised? 'Cuz <Cameraworld has the infamous reputation for phucking <with customers. Do they? I have ordered many times from CWO and had nothing but fine experiences. They will even match B&H prices except for grey market. I think the use of foul language indicates the overall low level of quality and thought that went into the above comment. _________________________________________________________ Do You Yahoo!?
