Would be good if Canon could design some kind of a lock mechanism to prevent pressing the lens release button by accident.

I'd like that too, in the meantime I'd be happy with an option for a much stiffer spring behind the current button; I'd be happy to pay a nickel for the part the next time I spent hundreds sending bodies back for service.

I'd probably do better to invest more time and less money.

Similar case but very different, I was doing the dirty "lens barely not locked in" trick on my 5DII once to prevent the camera from auto adjusting the Aperture in video mode. I had neglicted the fact that the lens was not locked in and at one point I needed to shift focus and whack, I didn't have a proper grip and dropped my 35mm lens... luckily it just dented the mount and the optics/AF are totally fine. But to say, at least in your case it wasn't the lens that dropped.

Also I do think the lens release button was accidentally pressed in your case

These are good stories, we'll bad actually, but good in the sense that I and I'm sure others will learn from your experiences.   Thanks for sharing, I will be more careful and mindful of this in the future.

I would be horrified to watch and listen to my 300 2.8 fall to the ground, :-*

Yes agree on a physical lock for the lens release button. Or an option to have to press the focus preview button at the same time to release the lens.

I often cover weddings, events and have somehow released both 70-200 m2 and 28-70 m2 lenses by accident. I am often holding the camera in different positions, above my head pointing down, from below, side etc.  Canon, please create an additional lock or safety measure!

While waiting for Canon to reinforce the lens release button, I strongly recommend getting a set of Optech Uni-loops and connecting them to the lug of your camera plate and to the BR carabiner.
Costs $6 and provides great insurance, without altering the position of your camera+lens combo.
