Nikon thoughtfully makes their polariziers wider than the filter thread - ie a 52 mm Nikkor polarizer has a front diameter larger than 52mm. My experience is that I can use this polarizer without vignetting on the 24/2.8 AiS. I don't use any other filter at the same time. If anyone is having vignetting perhaps it's because they left/put some other filter behind the polarizer. The HN-12 hood for the polarizer clearly indicates that it should be used only with lenses longer than 35mm - I've never checked. I just trust Nikon and don't try to use the hood with the 24! Now, regarding the Nikon/Canon BS going on here: It's of absolutely no value. I believe the purpose of this list is to share information about Nikon camera equipment. If I still shot with Kodak instamatics, I'd look for an Instamatic news list. I wouldn't be trying to convert you all to 127 cartridge film and focus free cameras. The purpose here is to learn to make the best photographs you can with the [Nikon] equipment you have - not to prove that what you have is the ultimate. Most camera equipment is better than most photographers. Peace and good light to you, no matter the color of your 300/2.8.
