The 6mm f2.8 and 8mm f2.8, however, work with the mirror in place, and actually let you view the image through the viewfinder! The 15mm f5.6 ultra wide, 13mm f5.6 ultra wide, and 15mm f3.5 ultra wide all seem to work with the mirror in place. And, in fact, everything introduced since 1972 does. I don't own any of these exotics, the info is from Moose Peterson's Nikon System Handbook. -- David Dyer-Bennet, <mailto:dd-b@xxxxxxxx>, <http://www.dd-b.net/dd-b/> RKBA: <http://noguns-nomoney.com/> <http://www.dd-b.net/carry/> Pics: <http://dd-b.lighthunters.net/> <http://www.dd-b.net/dd-b/SnapshotAlbum/> Dragaera/Steven Brust: <http://dragaera.info/>
