Hi Nikooneers, I kept some Cokin filters from my previous gear (a Canon A1). I tried to mount the filter holder with a polarizer filter onto my Nikkor 28-105 lens: The result was awful: huge vignetting! I have heard that some AF-D lenses accept the "HB-4 bayonet mount lens hood" that is supposed to snap onto the outside of the lens barrel -- not to the filter ring -- allowing a variety of filters to be used unimpeded and undisturbed. Do you know any adapter wich could mount on the bayonet and hold Cokin filters? Alternatively, I'm wondering which polarizer filter I could mount on this lens. Vignetting is already noticeable with the UV filter I mounted on it and I wouldn't it to increase with one filter ring more on it. By the way, I have got a F100 (I'm specifyin it since I read in the user's guide that the standard (?) Nikon Polar polarizer filter cannot be used with it. Only the Nikon C-PL circular polarizer filter is supposed to be ok (Why the hell I don't know!). Thanks in advance for any information, Thierry
