A couple of weeks ago Aperture suddenly didn't recognize my lens anymore. It has always did before. I use Aperture version 3.2. The lens is Canon EF 135mm f/2L USM, but now it only shows up as "Unknown (174)  135mm". My camera is 5D Mark II. When the lens is mounted, I can go into the camera's menu and read that the camera recognize my lens correctly. So why doesn't Aperture? Is the problem my lens, or is it Aperture?
