One of the more exciting announcements to come out of Photokina is the arrival of the new Olympus 25mm f1. 2 PRO lens. This surely is a lens that many have been waiting for for a long time and considering the design, it seems very worth it.
Olympus went through the trouble of completely redesigning the lens to make only a single element move when it focuses. This ensures that the lens has fast focusing. Surely, you also get the light gathering benefits of f1. 2 and weather sealing. With the Four Thirds crop, you're getting the equivalent of f2. 4 on a full frame camera--which means that there is no real reason to stop the lens down when shooting portraits or anything for that matter. . thephoblographer.com
