Macro Switar on Alpha.jpg

Kern Palliard (Bolex) 12mm Macro Switar

This lens is a preset type. That is there are two large levers, one is at the selected
f/stop and the other is moved to the selected position to stop down the lens quickly and
without looking at the lens f/stop scale.

This lens has a custom movable tube which allows two positions of extension.
A PVC tube is threaded to fit the front filter ring of the lens and a pentax screw body cap
is bored out to accept the tube. The assembly threads into a standard Maxxum T mount adapter.
Magnification at max extension about 6X

Konica-Minolta Maxxum 7 Digital
1/30s f/5.6 at 75.0mm iso400 full exif

other sizes: small medium original auto
