My only extension tubes are M42, so I attached the 9.5mm tube to my Takumar 135/3.5 lens. The usable focusing range seemed to be approximately 2 - 5 feet, not bad for butterflies. To get a few more MP, I used my Oly E-510. This gave me the equivalent of a 270/3.5 lens. This female Spicebush Swallowtail flew up and rested for about five minutes on the greenery on my fence. This was the only view and lighting that I had available. I tried focusing at several stops, and it was not too difficult. I suspect this was taken at f/8. http://www.gallery.leica-users.org/v/OldNick/Spicebush+Swallowtail+Female.tif.html Comments and critiques welcomed and appreciated. -- Jim Nichols Tullahoma, TN USA
