Dear All, For those of you who need a copy of the Nikon OTF files (40x, 60x and 100x lenses) I have placed these, along with the Zeiss and Olympus OTF files in a folder on zeus (zeus/ninewells/otffiles). I have also written brief instructions on how to use the OTF file. If you have any questions, please let me know. Cheers, Sam
