The original KOWA Anamorphic prime lenses have been produced until the 1970s and usually for four different primes are available: 40mm, 50mm, 75mm, 100mm. The Kowa Evolutions expand on this set with two additional focal lengths, a wide-angle and a telephoto 135mm, which match the Look of the original set.
The look and bokeh of the Evolution lenses is matches the genuine anamorphic look of the original lenses. The optical design is based on original optical design and the front anamorphic principles. They are low in contrast and warm in color and can be made to flare. The lenses are built in a compact, lightweight housing with modern cam driven internal focus mechanics. The focus throw has changed significantly compared to the originals. The Evolution lenses offer a 200° angle on the focus ring and a 100° on the aperture ring.
The 80mm front diameter offers ease-of-use of a clip-on matte box and a 77mm thread was added for use of screw-in filters. That makes them ideal anamorphic lenses for handheld, Steadicam or drone camera work.
