Michael, Two things to know about the 24 f2.8/HN-1 combo: 1) Have you noticed that that HN-1 is threaded to accept a filter itself? Rather than mounting the filter onto the lens then mounting the HN-1 on the filter, mount the HN-1 onto the lens then screw the filter into the hood's threads. 2) If you're using a brand of filter other than a Nikon L37c or L1Bc that has a thick mounting ring, you'll likely experience vignetting. You really need a Nikon filter or one of the 'thin-mount' third-party filters for the 24mm f2.8. I hope this helps, Mark Peterson ________________________ Mark Peterson Ames, Iowa, USA mailto:[EMAIL PROTECTED]
