Thank you I will I'm always glad to hear advices ! It maybe bad settings as you suggest. Just to get clear the shows I shoot are far from professional concerts which usualy have lot bigger budgets for the lights than the tiny french theaters I go in.
For info another user is reporting this issue.
I did not became aware of this behaviour myself, I read this post:

Before finding that post, I have spent days reading about focusing techniques, manual, auto, focus traps, try tripod, crouching, proning, shooting faster, all possible SEL 1-2-3 and almost all sensors and sensors disposition in AF.S and AF.C but never touched shutter priority and never used the live view so much (always in the same conditions, light, angle, lens..). I never asked on this forum because I was convinced I was the problem and my technique and/or settings were bad. I read that thread, try to disable focus priority, and got 85% of focused pics instead of 85% of strange focused pics. Nothing else but that setting changed.
Originally posted by monochrome Not my experience at all. I have used back button AF while holding the shutter button down in Focus Priority. I've not noticed a lag in any light conditions for AF.S / AF.C.
I never talked about the back AF button, maybe it works, but it's a choice to use it or not, maybe a workaround but not a solution, the lag i'm talking about is concerning the main shutter button paired with the view finder. My AF back button is set to allow manual focus for screwdrive lens like FA 50mm 1.4 as it doesn't support quick manual adjsutement when autofocus is on..
