This Rodenstock 40mm Rodagon-WA is designed for short column enlargers. It has a shorter focal length and larger angle of view than with standard focal lengths.
At any given enlarger height it yields an almost 70% larger projected image area than a standard focal length lens. This is useful for enlargements well above 10x magnification. This is achieved by using highly refracting glass types in the lens construction.
- Wide angle lens of superior quality for 35mm enlarging
