Vespa Twins -- Canon 1D Mark III & Pentax Ultra-Achromatic-Takumar 300mm f5.6. Larger Picture.
Tried out a very rare lens today -- Pentax Ultra Achromatic Takumar 300mm f5.6. One of a small number of lenses designed for infrared and other scientific uses. As a normal lens, it's very sharp even at f5.6, but I don't see anything special other than that it's made with two fluorite elements. Unless you have a very specific use, this lens is not worth the money (which was $1600USD in the 70s when introduced).
