JML 56mm F1.9 Lens in Prontor-Press Shutter
This is the legendary JML (made by Steinheil) 56mm F1.9 lens. Originally, it was designed to be used as an extreme macro lens for 4X5, with magnification of 1:1 and more.
Covers 4X5 at close up, but has a smaller image circle when focused at infinity.
An amazing super wide lens for a pack film conversion project, or extreme macro use on any camera.
Some minor dust specs inside. Otherwise, multi-coated glass is clean.
Shutter is good and responsive at all speeds. Speeds sound accurate throughout the range.
Aperture position indication chart manually inscribed.
