The apochromatically corrected high-performance lenses of the ApoRodagon-N series guarantee perfect results which will satisfy the highest demands.

The correction of the 7 element lenses (6 elements for focal length 50 mm) was given highest priority and so ensures the full elimination of irritating visible colour fringes on high-contrast borders. Al1 monochromatic imaging errors have also been greatly reduced to give this lens type its unsurpassed image reproduction performance.

The advantages are clearly visible in both colour and black and white enlargements. The Apo-Rodagon-N is therefore the amateur's and professional's first choice whenever the very highest reproduction quality is required.

The optimal working aperture is reached by stopping down by only 1 to 2 stops.

All Apo-Rodagon-N models have a click-stop diaphragm and an illuminated aperture display. Up to focal length 150 mm they also offer a pre-set aperture and allow the click-stop to be disengaged for stepless control.
