Bright f1.2 Aperture Splashproof, Dustproof, Freezeproof Construction Z Coating Nano Manual Focus Clutch Programmable Lens Function Button 50mm Focal Length (35mm equiv.) Ultra-High Speed AF Mechanism MSC Movie & Still Compatible Lens Hood included 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. We've assembled 19 lens elements into 14 groups to create the most complex Micro Four Thirds lens ever made, including Super ED, ED, E-HR, HR, and aspherical elements. Spherical and chromatic aberrations that often occur in fast, prime lenses are eliminated. Color fringing is thoroughly suppressed. All that's left are clear, crisp images you can't wait to show off. The Most 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 in both focused and defocused areas, even with a wide open f1.2 stop. Paired with the ultra-high resolution of the focused areas, the defocused background creates a natural looking three-dimensional effect. Shoot stunning portraits with sharp details and beautiful bokeh that emphasizes your subject in both bright and low light. Exhilaratingly-Fast Autofocus Many autofocus lenses have a trade-off: they use multiple moving elements to reduce aberration, but their focusing speed slows down as a result. Fortunately, there are no sacrifices with the 25mm f1.2 PRO. At the heart of its design is a lightweight inner focusing mechanism that uses a single lens element. It provides ultra-fast ultra-sharp autofocus performance, even at the lens' widest f1.2 aperture. The Movie and Still Compatible mechanism provides quiet, smooth focusing - a must have for videographers. Technology Creates Versatility The 25mm f1.2 PRO uses a tandem of coatings for ultimate shooting versatility.
