The apochromatically corrected high-performance lenses of the Rodenstock Apo-Rodagon-N series guarantee perfect results which satisfy even the highest demands.
The correction of these excellent lenses with up to 8 elements was taken to the absolute limits and so ensures the full elimination of irritating visible color fringes on high-contrast structures. All monochromatic aberrations 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 amateurs' and professionals' 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.
Use 50mm lens for enlarging 35mm negatives.
