Dear all,
I have a Steinheil Orthostigmat that seems to be a convertible design. Front and back combined gives a focal length of 13.5 cm with max aperture of 6.7, front has a focal length go 26cm and back 22cm.
If I want to use just front or back element, what kind of aperture will I get? It is not indicated on the shutter as some of the old convertible lenses seem to have.
Thanks
TY
