product description

SOLD OUT!!!

Vixen’s original high performance 4-element lens is employed. Despite its short focal length, spherical aberration and image field curvature are reduced to 1/3～1/5 of the original amount by dispersing the power to each element of the lens. Sharp central images and excellent peripheral images (1/3 of achromatic, less than 60 microns) are obtained.
