Hi, I just got my olympus 12-40 pro lens and I love the darn thing! So here is the problem. Right when I am about to shoot the fireworks, I went to focus and nothing. So I thought the focus ring was on manual but it wasn't the case. So, I decided to remount the lens and nothing Also, reseted the setting on the camera nothing again. I am guessing its a firmware issue since the camera is on firmware 2.0 and the lens is on 1.0. Or the lens is defective. Any suggestions? Thanks!
