A six element, six group optical design maintains even sharpness and illumination from edge to edge, the recommended working aperture is f/11, and its recommended scale range of 2x to 10x benefits making mini enlargements up to mural-sized prints. Additionally, for ease of use, the lens is fitted with an illuminated f/stop scale, a convenient preset aperture setting, and a click-stop diaphragm that can be de-clicked depending on preference.
