Have used now 2 different D300 bodies, with my 17-55 f2.8 Nikkor lens... On both of these bodies, I see something that I can only describe as a halo effect around anything shiny [reflections off painted surfaces, chrome, metals etc]. Kind of like what I would see from cheap glass. OK I also shot with my 50mm f1.4 and guess what........ same thing. I don;t see this using a D200, or a D80..... Back to back shots using different camera bodies, with these lens.. Big differences. GRRRRR. I shot with the camera store guy standing over my shoulder, then inside to print. OK I can only assume they all are like that? I can keep taking back camera bodies but it is a waste of time. Looks like I will wait until Nikon gets it together with their sensor to step up beyond the 2/200 series? Anyone else notice? I dunno bout you but I want to ee a crisp reflection, not a blurry halo..
