To catch a glimpse of what I have been having fun with the last couple of days you are invited to view a "slide" presentation with text of how I modified the back of a Canon FD lens so that it would fit on a Canon EOS-type body while maintaining focal length, image quality and infinity focus ability. See at: http://www.rit.edu/~andpph/text-adapt-canon-lens.html I think the file size for this PowerPoint prepared presentation is much larger than I would prefer but I don't know how to set PP to make a smaller file. If you know how or have a suggestion let me know! ;) AndyD
