Super wide angle lens with the widest angle of view in 645 lenses for photography with expansive width

To achieve matching with digital images, the latest optical system uses two aspherical lenses (including one double-sided aspherical lens) and the new Aero Bright Coating for significantly reducing the surface reflections. This minimizes the various types of aberrations while also providing a unique expressive result based on the strong perspective, wide angle of view, and impressive depth of field that is possible only with super wide angle lenses. A round iris diaphragm up to F8 is used for natural rendering of out-of-focus (bokeh) effect for point sources of light (Note). This lens includes an ultrasonic motor for smooth AF drive (SDM) operation, Quick-Shift Focus System enabling AF/MF switching in realtime, inner focus system, dust-resistant and drip-proof construction, SP coating for repelling dirt and oil on the lens surface, and more features, for combining superior functions with high operability.
