Hello all,
Wondering if anyone has ever experienced this problem before? Just picked up a Canon EF 75-300mm III lens and it seems to work fine on all my cameras when shooting indoors. As soon as I get outside, error 99 comes up on my digital camera, and a flashing bc code comes up on my film camera. As soon as I go back into my house, we're back to normal. No hesitation or error codes. What the heck does that mean? Do I have gremlins? Camera and lens only seem to work properly in full auto mode. If I switch to Manual or AV, camera goes into error 99. I go back to full auto, I'm fine again. All my other lenses work as they should in all modes. Hoping someone might have an answer.
Mike
