Need advice on a problem that came up last night while I was shooting a basketball game in AV mode. I couldn't get a good shutter speed, meaning it would default to like 30 instead of something around 500-1000 shutter speed I have seen in the past based on the 1.8 aperture setting I had with my 85mm lens. I initially got a message that said the lens and camera conection was bad and to clean the contacts? The gold contacts look clean to me. Tried two other lenses( 50mm and 70-200) and no luck. Went back to the 85mm lens and shot some in shutter mode.


Switced lenses to the 70-200 at half time and shoot in shutter mode. Then I tried AV mode one more time with this lens and it worked fine? But I had this same lens in the camera when the problem first came up to rule out the 85mm lens being the problem.


Any thoughts?
