Description
Dedicated to extreme close-up imaging, this lens is a specialized macro lens for photographing subjects at magnifications greater than life-size.

Carefully designed to extend the short working distance of traditional 25mm lens in order to provide sufficient room for lighting hitting the subject. Operating within a 2.5:1 to 5:1 range, this lens has a minimum focus distance of just 6.8″ at the 5:1 magnification along with a comfortable 1.6″ working distance. (40mm @ 5:1 , 45mm @ 2.5:1)
Complementing the close-up capabilities, the optical design incorporates 8 elements in 6 groups with a extra-low dispersion element to deliver an unprecedented corner to corner sharpness. The extra-low dispersion element reduces color fringing and chromatic aberrations for a high degree of clarity.

Wide-angle design with magnification range from 2.5 to 5X benefits the high magnification design by providing greater depth of field compared to telephoto or long lens designs. Moreover, manual focus operation for precise control over focusing distance when working with close-up subjects.
