The Rodenstock 45mm f/4.5 Apo-Sironar digital Lens with Copal Shutter & Lens Board from Arca Swiss is optimized for digital imaging sensors and chips. It comes with a mechanical Copal shutter and lens board. Also, the lens produces a 125 mm image circle for formats up to 72 x 96 mm in size. This allows for large movements without a decrease in image quality.
The lens is designed for use with medium and smaller format digital sensors, which are sensitive to diffraction and low-light conditions. This is done by optimizing the working aperture to between f/8-11, minimizing diffraction while still letting in a moderate amount of light. Additionally, this lens has been specially corrected to nearly eliminate distortion and curvature of field.
The Copal shutter is a purely mechanical stepless shutter with manual cocking. It features bulb and timed shutter features. Also, it comes with a lens board for mounting to a view camera.
