it gets too hot to do the hq modes, the 4k60/120 and 8k with ease after shooting photos. . so only those options are locked out. everything else is fine. u have to be mindful of that if u do video and photos on one body.
You may not have seen my later post. Below are the results of my own test.
Battery Test of 7Dmk2 vs R5
Conditions: 80 Degrees, Intense sun at 6500 feet. Windy
Began test 11:35 am, Using interval timer on both cameras set to unlimited with 7 seconds between exposure.
7Dmk2, 40mm lens with AF on. Battery began test at 94%, it was an old battery with poor recharge performance, one square showing.
It ran for 2h09min before the battery died. 1015 shots.
R5 15-35mm lens with AF on, Battery was at 100 with 3 squares showing on the recharge performance. Brand new LP-E6NH, Electronic first curtain shutter, Rear LCD closed. Using only SD card, CF Express cards have not arrived.
It took 1145 shots before I it cut it off. It was showing 12 % battery at that point.
I then took 215 more shots in a several burst and 3 minutes of HD videos and checked several video formats for the time remaining. Total stills were 1360 plus 3 minutes of video
This is what was showing at that time.
FHD 29.97 IPB Rec time 7:42:56
FHS 58.94 All I Rec time 1:17:04
4k-u 29.97 All I Rec time 29:27
4k-u 29.97 IPB Rec time 01:55.39
4k u 59.94 IPB Rec Time 59:32
4k d 59.94 All-1 Rec time 29:05
8k-d 29.97 IPB Rec time 28:50
Other Formats were showing zero, I assume due to no CFexpress card.
At this point the Battery was showing 2%. I never saw a heat warning.
Knowing that I had a weak battery in the 7Dmk2 I was not surprised that it quit early. With a good battery it would easily get to 2k shots plus. My conclusion is that for me I should get 700-1000 shots with R5 on a good battery. I will be carrying 2 extras batteries not 1 when using the R5.
