The Schneider-Kreuznach Xenotar 135mm f/3.5 is a fast large format lens with a 5-element, 4-group design and 59-degree angle of view. With a 153mm image circle covering 4x5in format as a slight wide-angle, at 380g with an M 58 filter thread in a Compound I shutter, it provides a bright focusing image. The Xenotar 135mm was valued for portrait work on 4x5 cameras where its fast aperture and smooth rendering excelled.
