Shutter release lag
I have a 350D and use a variety of lenses with the body. Recently after about an hour of shooting, my shutter release lags anywhere from 1-3 seconds. If I keep the shutter release button pressed down, it will eventually work. I attempted to change batteries when this happens with a fully charged unit, but the issue persists. I have also cleaned the contacts on the lens to body connections, reseated the CF card and ensured the CF card door is closed. I have also moved my lenses to manual focusing to see if that is the issue, but it does not. I also remove and reinsert the lens to see if that helps, sometimes it does, sometimes it does not.
I am using the following lenses with my camera body:
Canon EF 70-200 L 2.8 IS
Canon EF 24-105 L 4.0 IS
Any insight would be greatly appreciated.
