Have you bought it second-hand?
Is your 1DMK3 "blue-dot"?
Otherwise, you can upgrade to latest firmware and it should give you more info about "whats wrong". Err99 usually meant its mirror issue (needs to be fixed by Canon, sorry), but ofc it might mean something else, unfortunately beyond our reach to find out "what is wrong".
It might or might not go worse. I wouldnt push it personally..
Thanks .. It's a yellow dot, and I did buy it used. It had 1.23 firmware and I upgraded to 1.3 a few days after first noticing the Err99 thinking that it may clear the problem, but it didn't.
And I think you're right about it being a mirror issue as after getting the message and turning the camera off the mirror goes up (like it would with MLU or sensor cleaning) .. then goes down again when you turn it back on.
And it does not have any problems on startup with no lens attached .. it just starts right up and works fine.
No lens attached without problem? Hm, might be some problem in AF circuit, but its just wild guess.
Have you tried fast shutter speeds at high f-stop? 1/8000 at f11-f16 - It can sometimes show if shutter is fine or not. If theres light-streak across pic, its dying shutter. But I think it doesnt work always, just saw it few times.
Really hard to say, service is best idea right now I think.
