Manufacturer description #1
When the total length of a telephoto lens is shortened, aberrations tend to increase so that it has been considered optically very difficult to produce a compact lens free of aberrations. Mamiya's own optical technology has been able to surmount those design perplexities and the 500mm f/6 is proof of that innovation. It is 20.5mm shorter than the RB500mm and like the 350mm, combines two lenses that use ultra low dispersion glass with four that use anomalous dispersion glass: all chromatic aberrations within the 400 to 1,000nm range have been eliminated. In addition, all longitudinal distortions in the form of spherical aberrations, astigmatism and curvature of the field, have been corrected to less than 0.1mm: coma and flare are a thing of the past. Thus, crystal sharp, high contrast, high resolution images are generated. Picture deterioration due to distortion caused by spherical aberration and curvature of the field in short distance photography have been rectified and likewise are a thing of the past. Pincushion distortion is less than 1%.
Manufacturer description #2
The 500mm f/6 APO is the longest telephoto 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. The 500mm APO lens includes tripod support bracket. Applications include long distance landscape, aerial, industrial and wildlife photography.
