Manual focus - Adaptall mount

This lens establishes a benchmark as a standard lens, extending from a wide 28mm all the way to 105mm telephoto, all with a fast constant 2.8 maximum aperture. The use of four large diameter aspherical elements and three LD glass elements reduces various aberrations while minimizing the fall-off of light at the corners.
