p.1 #1 · p.1 #1 · 1D Mark IV mount problems - what to do? {RESOLVED} | |
Another one bites the dust!..
Today, in the middle of a shoot, my camera stopped communicating with the lens (my new 16-35/4 L IS), giving 00 for aperture on the top display, and Err 01 (lens-camera communication failure) when attempting to fire the shutter. At first I blamed the dirty contacts on the lens and decided to clean them afterwards, but the failure persisted when I switched to another lens, the old 70-200/2.8 IS. With it mounted, I noticed a more ominous behaviour: the lens would wobble slightly, as I was able to rotate it on the bayonet a very small amount. When I did so and rotated it - with an audible click - counterclockwise, the contact resumed and I was able to shoot normally. When I spun it - whether intentionally or not - back clockwise a little, the aperture went 00 again.
When I came home, I tried most of my other lenses (16-35/4, 24/1.4, 50/1.8) on. The behaviour is the same with every one of them, but none (save the old, and presumably well worn) 70-200 give any noticeable (nor audible) rotation: there's just a tiny bit of movement that brings the contacts out of touch and the error sets in.
So what are my options (short of ignoring the problem and just shooting on, carefully checking whether the lens is in the "right" position everytime - which I'd rather avoid, as there's a high chance of failure whenever I become less attentive)? Cleaning the contacts anyway, trying to tighten the mount screws on the camera (and the screws that keep the contact pad in place down in the bayonet's throat), or just sending the camera in for repairs?
