Aperture/Iris control stopped working?

PostFri Mar 29, 2013 6:51 pm

Hi all,

I'm hoping you can help soon. I'm currently on a shoot out in Marbella with the BMC. I've been shooting with the Canon 16-35mm 2.8 L and 50mm 1.8

Generally the camera has been fine BUT, this morning the aperture control on the 16-35mm randomly stopped working. I tried remounting the lens and restarting the camera but it still wouldn't come back. I also cleaned the contacts and this did nothing.

I put the lens straight onto my 60D and continued to shoot with that and had absolutely no problems at all which struck me as strange. When we finished on set (approx. an hour later) I put the 16-35mm back onto the BMC and it started working again with no issues whatsoever. However later on we were shooting outdoors and it's happened again and nothing seems to be solving the problem.

Can someone point me in the right direction?

Many thanks!
