Manufacturer description

The beauty of nature from spring to summer can be captured using this new angle of view combined with color film.

From the editor

The only lens with the Leica screw mount produced by Olympus.

Optically, the lens consists of 5 elements in 4 groups: three separate elements at the front and a cemented doublet at the rear.

The serial numbers of known copies of the lens are in the range 60xxx - 61xxx, therefore, no more than 2000 lenses were produced in total.

The lens came with a dedicated viewfinder and both front and rear caps.
