The apochromatically
corrected high-performance lenses of the Apo-Rodagon-
N series guarantee perfect results which will satisfy the highest
demands.
The correction
up to 8 element lenses was taken to the absolute limits and so ensures
the full elimination of irritating visible color fringes on high-contrast
borders. All 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 color 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. |
