Asking $3700 as it is in mint condition with original box and pouch.
In addition to the Phase One camera platform, this lens can be used on the Leica S and Sony A7/A7r with adapters due to manual aperture control. I believe it has a 96mm focal length equivalent in 35mm format.
Great for still life photography as it offers Tilt & Shift capability. Amazingly sharp optics!
