MS Optical, a Japanese one-man business best known for their lens conversions, are about to introduce what is probably the tiniest lens ever made for Leica M-mount: the Super Triplet Perar 28mm f4. Successor to the very popular and critically acclaimed Super Triplet Perar 35mm f3.5, the new Perar 4/28 manages to beat its already minute predecessor in terms of size and weight. Coming in at only 45 g (1.58 oz), the lens is based on a triplet design comprising only three lens elements. To make the optical formula even more compact, the lens’ aperture is placed before the front element. More details after the jump.
