Do you need a standard focal length for your Micro Four Thirds camera? Yongnuo has just announced the Yongnuo 25mm f/1.7 ASPH lens for the Micro Four Thirds mount. This new lens contains an aspherical element, which makes lenses more effective in how they manage light and aberrations. 

This is the first time that Yongnuo has produced an ASPH lens. This means that it should be better at handling chromatic aberration, which is the color fringing that can appear in the high contrast areas of an image.
