Zeiss Ikon Voigtlander Icarex 35S/ Carl Zeiss Ultron 50mm F1.8

Zeiss Ikon Voigtlander Icarex 35/ Carl Zeiss Ultron 50mm F1.8

Mount: Icarex BM

The camera is not in working condition. Winds and fires but not tested or offered as working. The lens is in amazing condition, glass is clean. Lens has original screw on rubber hood.

The beauty about this lens is that you can always shoot it wide open at f1.8. While some lenses will be soft when shot wide open, the Ultron still delivers outstanding sharp and detail rich images and vivid colours. Combine that with the unique creamy bokeh and you have the perfect portrait lens.

It performs much better than all other 50mm prime lenses and always delivers outstanding image sharpness combined with an outstanding bokeh. I therefore think this is one of the best 50mm prime lenses that you can get. With a minimum focusing distance of 45cm, the Ultron is also a good macro performer, which can also be useful for portraiture.

Unfortunately it is rare and expensive.


This particular lens design makes it a unique and exciting lens to own for collectors and photographers alike. No other lenses utilise the same optical formula. Color-Ultron 50mm f1.8 succeeded this lens and was designed by Dr Erhard Glatzel. It had a slightly convex front element, as opposed to concave glass element present in this lens.
