I'm increasingly getting the Error 01 code (The communication between the camera and lens is faulty) with both my lenses, so I'm guessing it's the body. Removing the lenses and putting them back on helps for a few shots, but then it's back to the err...
Not noticing light leaks. Could it be humidity? It's been rainy and humid here, but today is dry, and I've tried changing the lenses and turning the camera on and off several times, and haven't had the problem (so far).
