Rodenstock Apo Sironar N 300mm f/5.6 Lens in Compur electronic #3 (Sinaron S)
Latest version of the Apo Sironar N line.
APO glass, one of the most advanced LF lenses ever made.
Apo Sinaron S branding was for sale under Sinar's own brand.
Lens in good, used condition.
Compur electronic shutter works as it should. Fresh battery installed. Uses standard, readily available batteries. Battery is good for thousands of exposures, so this should last a good few years either way. This shutter features electronically timed exposure settings, from 1/200th all the way to 32 full seconds. 30% better accuracy than mechanical shutters. No mechanical escapement, never requires service.
Aperture scale was adjusted to conform to this 300mm lens and is now spot on.
Includes retaining ring and both front and rear caps.
We have many lens boards in stock, for most cameras - just ask.
Please see detailed photos.
