R1 overheated and shutdown shooting stills

[WDonnelly]

Shooting a Lacrosse game today with an R1, RF100-300/2.8 with a Canon 2x extender, Lexar Pro card, monopod. I saw the overheating symbol but thought that was for video. In the middle of the 4th quarter (~2,300 activations), the camera displayed a message indicating it had overheated and was shutting down. It did. WTH??? There were still 4 minutes in the game. 

A cloudless, 80-degree day, a little after high noon. As I recall the settings, high-speed (not H+), evaluative metering, AV priority, fixed ISO, used the EVF not the display, autofocus, electronic shutter. 

This is shocking. As I get into HS playoffs in May, it will be 90+ degrees. Imagine a close game in the 4th and needing to shoot post-game trophy presentations. Or, like a baseball game last year, a bases loaded squeeze bunt to win the game and the camera shuts down!!! It would have been a disaster. 

There was another post on overheating but the shooting situation was a lot different than mine. 

Anyone else experience this?

FYI on real-world R1 battery life. I've attached the current battery status on the camera. I haven't recharged it since yesterday's game. I know your experience is different, but I can usually get 2 games on one R1 battery charge.

How long do these shooting sesssion last>. The manual has overheating warnings all over the place.  If the setting below is not disabled then I suggest that you disable it.  Keeping it enabled is not all that different from shooting video continuously for hours on end.

“ Over 2300 activations over about three hours is a LOT.  Does that number reflect how many images you captured or how many bursts you initiated? “

We never got an answer to that question. To say “activations”, instead of “shots”, is an interesting choice of words. It still sounds like high speed bursts, not individual shots.

Over the course of say close to a three hour game, that’s almost 800 bursts per hour and more than 12 per minute.  Or, a new burst is activated roughly once every five seconds!

Furthermore, if “Pre-Continuous AF” is enabled, then you’re practically recording non-stop video for nearly three hours.  No wonder the camera overheats.
