35mm 1.4 prime Auto Focus not working

Hello! 

 

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.

Why do so many people say "FER-tographer"? Do they take "fertographs"?

No I tried that. Even took of the lens and back on, took out my battery, switched lenses, all that and nothing.
