M.Zuiko ED 25mm f1.2 PRO at a Glance: One of the most versatile high-performing prime lenses ever manufactured. High Performance: M.Zuiko PRO lenses are built for the highest level of performance, incorporating fast apertures and weathersealed construction. Exceptional Sharpness: It's all about the glass. Our 25mm f1.2 PRO achieves spectacular edge-to-edge sharpness - even at the maximum f1.2 aperture - thanks to its incredible collection of glass. Beautiful Bokeh: If you love shooting with shallow depth of field, the 25mm f1.2 PRO does it beautifully. Its high optical performance eliminates aberrations, distortion, and fringing. Fast and Accurate AF: Many autofocus lenses have a trade-off: they use multiple moving elements to reduce aberration, but their focusing speed slows down as a result.
