The ISCO lenses are extremely high quality, lightweight, and beautiful lenses. They are essentially the exact same as Schneider Cinelux Ultra MC, except without an unscrewable barrel design.
It is rumored that the ISCO Ultra MC is slightly higher image quality than the Schneider Cinelux, although we won’t attest either way.
These lenses are sharp, produce beautiful, smooth bokeh, and offer a largest aperture of f/2.
Focal lengths for medium format film adaptation range from 90mm-170mm.
