Product Description The Pentax 300mm f/4 ED (IF) manual focus lens is roughly equivalent to a 180mm lens in the 35mm format. It is suitable for portraits, fashion, sports and nature photography. Pentax lenses have been developed using the latest in computer-assisted optical design technology. Lens surfaces are treated with Pentaxs exclusive Super-Multi-Coating for sharp, high-contrast images. ED(IF) lenses are super high performance lenses incorporating special Extra-low Dispersion (ED) lens elements to assure the highest image quality and minimize chromatic aberrations. The Inner Focus (IF) mechanism minimizes lens extension when focusing, maintaining good balance and assuring smoother focus ring operation and a closer minimum focus distance.
