After seeing Moose's recent fly captures, I became interested in trying
an extension tube, though I don't have any of the modifying optics he
has been using. 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.
