ZUIKO MACRO 50mm F3.5 Primarily designed for close focusing, this lens meets the photographer's most exacting definition demands for close-ups, copying work and macrophotography. Usually in lenses of this type the lens barrel tends to become elongated at the closest focusing distance, but the new design made a very compact configuration possible. Additionally, this is the first time that an automatic correction lens group that compensates for close distance aberrations has been built into a macro lens.  Because of this new design, this lens provides high resolution from infinity to close distances up to 0.5X magnification.  With the Extension Tube 25, the limitation is extended to 1X life size. But to get best results the use of 1: 1 Macro 80mm F4 in conjunction with Auto Bellows is recommended. Accepts a 49mm threaded filter .

• Correction of Aberrations at Close Distance Focusing (floating elements) In general, lenses are designed for maximum performance at infinity. Accordingly, when the lens barrel is fully extended to the shortest focusing distance, resolution is reduced. Although this is negligible for ordinary lenses, it becomes increasingly important in lenses specially designed for close distance photography. The new ZUIKO mechanism moves certain lens components as a unit automatically correcting for aberrations.  This assures high lens performance throughout the focusing range.
