Lens Description: The Horseman 135mm f/5.6 Apo-Sironar-S Lens is a Rodenstock 135mm Apo-Sironar-S with a standard Copal #0 shutter, but built into a Horseman-specific helical focusing mount and barrel assembly made to fit upon their SW612/SW612 Professional medium format cameras. Used with a 6x12 film back, this lens produces a 45° x 23° field of view, with a normal perspective and plenty of shift capacity when used upon the 612 Professional.rnrnThe Sironar-S stands head & shoulders above the rest of the tried and true 6-element/4-group large format lenses thanks to its ED glass. This lens can be used with exceptional sharpness even at apertures which are far from ideal in the world of large format.
