Manufacturer description #1

By combining two lenses which use ultra low dispersion glass with one that uses anomalous dispersion glass, the utmost in chromatic aberration correction has been achieved. Since spherical aberration is negligible, halo or aberration flare has been eliminated while coma and astigmatism have also been corrected to a significant extent. Chromatic aberration free, the 210mm assures high contrast image quality over the entire plane at open aperture. Even when stopped down to small apertures, resolving power and contrast remain almost unchanged. At f/11, however, there may be an indication of some deterioration in quality due to diffraction. The spherical aberrations and fluctuations that result from the curvature of the field in close-up or short distance photography have also been eliminated. Pincushion distortion is less than 1%.

Manufacturer description #2

The 210mm f/4.5 APO is the shortest focal length in the Mamiya RB APO series, utilizing ultra-low dispersion glass and computer aided design to eliminate chromatic abberation common to telephoto lenses over 200mm focal length. Resolution, color reproduction and overall sharpness are enhanced at all apertures because chromatic abberation is eliminated. Applications include fashion, beauty, portraiture, commercial, advertising and industrial photography.
