This high-resolution macro lens is designed for 4x~12x magnifications (object sizes 8x5mm~3x2mm). High-magnification macrophotography. This lens must be used in conjunction with the Auto Bellows and Objective Lens Mount PM-MTob.
Because the aperture is manual, stopped down metering is required; focusing is easier with the aperture wide open.
Compatible focusing screens: 1-11, 1-12.
