Realizing a truly wide perspective, the Super Wide-Heliar 15mm f/4.5 Aspherical III Lens from Voigtlander features an updated design that is enhanced for use on mirrorless digital cameras as well as classic M-mount rangefinder film cameras. The 11-elements-in-9-groups optical design incorporates one rear aspherical element to control chromatic aberrations and minimize distortion, and also helps to produce consistent peripheral illumination void of color fringing. The manual focus design affords a minimum focusing distance of 1.6′, which pairs with the wide depth of field for sharp imaging from near to far. Rounding out this versatile, super-wide optic is an integrated lens hood to reduce lens flare and ghosting, rounded 10-blade diaphragm, and the ability to accept 58mm screw-in filters.
