Manufacturer description

Aberrations reduced to the ultimate value along with the TAKUMAR 83mm lens. Even with the diaphragm full open, the resolving power is excellent, producing brilliant brightness to every corner of the picture. Indispensable for long distance or portraits. Capable of close-ups of animals or plants at a distance.
