My 2nd T6s has the same flaw.

[PajamaGuy]

While shooting one of my grandson's  AAU baseball game, my 3-week old T6s exhibited a flaw.  Although I can't recall the exact steps, and therefore can not duplicate the flaw on-demand, I've experienced it with my T3i, and both T6s'.

When using Back-Button-Focus in conjunction with AI Servo and Continuous Shutter and while taking rapid groups of sequential shots, the BBF button (AE/FE Lock) magically becomes a shutter-release button.  And when that happens, the actual shutter button sometimes triggers the Continuous Shutter action which then keeps shooting even when all buttons are released.  (flipping power off/on resets it).

When I explained the issue to Canon, they had me send in my 1st T6s, and they sent me a new one.  The same day I received the replacement it too exhibited the flaw. - BUT - I do love the camera and would buy it again!

The pitcher told me it did hit his elbow (immediately before this shot) - he actually got a pinch runner.

"The one good side of this problem is that it sounds like something that should be readily fixable in firmware, once the Canon technicians get their heads around what's happening."

I agree - I just wish I could identify the steps necessary to reproduce it "on demand".  I was an I/T Director for the Space Shuttle Program, and I know the frustration of, "It shouldn't happen, I believe it does, but I'd like to see it for myself!"

All of us who work in IT are familiar with that frustration. And we all know how easy it is for almost any embedded computer to fall victim to timing issues that can be very difficult to track down.
