Protar IIa, E. Kraus under license from Carl Zeiss
A new generation of lenses was born in 1890 with the Protars designed by Paul Rudolph in Jena, Germany for Carl Zeiss. They were anastigmatic, significantly improving the sharpness of images even far from the axis of the lens and even at its widest apertures.
1894
Ross, under license from Carl Zeiss, Protar VIIa
The pinnacle of Protar development, this lens is very complex and difficult to produce with its 8 elements in 2 groups (4+4). The result is astonishing and no one can imagine, looking at your photos, that this is a lens that is more than 100 years old.
