70mm mounted objective: $15 shipped **SOLD**

This is a metal cell with three 70mm lenses in it. With all three lenses the group has a very short focal length, probably about f/1 measured from the center of the cell. But if you remove one of the lenses and leave only two in the assembly the focal length is much more reasonable though still fairly fast on the order of f/4 or so (rough estimate only - I haven't done any accurate measuring.) $15 shipped in the conus.
