Information from Leica:
With an imaging performance even greater than that of the COLORPLAN-PRO, this projection lens becomes the top-of-the-line product that meets the very highest demands. It's highly corrected optical system, with five multi-coated lens elements, produces excellent resolving power as well as uniformly high contrast and crisp sharpness across the entire image area.
