Egami Spots Olympus Patents for Ultra-Fast Lenses
Japanese camera and imaging blog Egami has spotted Olympus patent applications for two 12mm f/1 and two 14mm f/1 AF lenses. The Micro Four Thirds (MFT) system already offers an assortment of f/0.95 lenses, courtesy of Cosina and SLRmagic - but these are all manual-focus lenses, whereas the patent-pending Olympus designs would allow for the incorporation of auto focus. Filed on 19 August 2012 and published on 20 February 2014, these patent applications include elaborate technical drawings that reveal some extremely complex optical designs, prompting Egami to speculate that software correction might be necessary to elminate chromatic aberrations and geometric distortions. In addition to the two 12mm and two 14mm MFT lens designs, Olympus has also filed patent applications for similarly fast lenses intended for smaller-sensor cameras - a 9mm f/1 lens covering an 1" sensor and a 5.46mm f/0.95 lens matching a 1/1.7" imager.
