Dallmeyer 2" (50.8mm) f/1.9 Dallcoated
cine lens with C mount. This is a later version of the Dallmeyer Kinematograph lens. If needed, the C-mount can be easily unscrewed to achieve larger image circle (about 1.2x crop on 35mm full frame to eliminate dark corners) and adapt to other cameras.
The lens is overall in near mint condition. Glass has no scratches, no cleaning marks, no haze (maybe a couple of extremely faint spots barely noticeable with a point light), no fungus, insignificant dust. Aperture opens and closes easily with no oil on blades. Focusing is smooth.
Cosmetically it looks very clean with no scratches or dents, only few very light tiny scuff marks on the focusing and aperture rings.
