I have another one of these on another auction, both are in a very similar condition...

A nice piece of glass... 4" (100mm) f2 projector lens.. these are (NOT) Double Gauss design (thanks to ebayer messaging) and are in fact a Petzval design... quite heavy weighs just under 600grams, glass has no fungus or scratches but there's some haze and cleaning marks, dust and some dirt right around the very edge.

Large image circle, covers full frame and even medium format digital with ease.

The examples shown were just take with a Sony A7 full frame camera just by holding lens to an extension tube to camera.

Distance from rear element to film plane is approx 45mm so gives enough space to adapt to digital.

Please ask any questions - there are highly regarded projector lenses.

NO OFFERS PLEASE
