Here you a very handy lens made by the german company Emil Busch Rathenow. This specimen features the well known Aplanat layout, which also was marketed under the name 'Rapid Rectilinear'. The focal lenght is 340mm (or 13.4") at a max. aperture of F8.

The Aplanat is a very well corrected and super sharp lens design, which was highly praised in the early days of photography.

The condition of the lens is very good. The brass is authentic and shows only minimal wear here and there, but also a fantastic and authentic patina. The glass is in a good condition, only minimal cleaning marks here. There is no haze and no fungus. The aperture is complete and moving freely.


The lens comes with a fitting flange.
