This is an interesting lens that was made for an Oscilloscope. It was designed to be able to make images at very close focusing distances. It is also optimized for a 1:2 reproduction ratio. I've read that it can be mounted on a mirrorless camera, and you could even try it on a 4x5 (it produces "liquid" bokeh!) Keep in mind that it will not focus to infinity on a 4x5 camera.
It is in excellent- condition with light to moderate wear and works perfectly. There is some minor separation behind the glass element, and it does not come with the electronic shutter cable. Otherwise, the glass is clean and scratch-free with no haze, fungus, nor other issues. The shutter is strong and accurate at all speeds.
Lens caps are included.
