My 35mm 1.4 acting up on me in the middle of a photoshoot. I always leave in auto focus and the red censors suddently stopped focusing or even making a noise. Manual mode worked fine. I took off the lens and placed back on and still same problem.

Occasionally I bump the AF/MF switch on my 35mm while getting the camera out of the bag. Did you click it to MF by accident? Try clicking to MF and back to AF.
