Dumb R5 Questions (for stills)

After having shot with a 5R over the last few weeks I've noticed a couple things. I'm not sure if they are bugs or working as intended. I've shot with the 5D series of cameras since the original 5D way back when and most recently with the 5D4. This is my first experience with mirrorless and the R5 a great deal of depth to its settings - not sure if I missed something.

1. Every time the camera powers down or I switch cards I have to refocus. Is this just a mirrorless thing? This certainly isn't game breaking, but its an inconvenience
- Fixed with camera settings

2. 12 FPS - When I first got the camera I would get the GREEN H+ icon with a couple of my lenses. I understand that only the newer lenses can achieve this. Now I only get the WHITE H+ icon - no matter what. I've double checked all my settings and it should be good to go for 12 fps - fully charged LP-E6NH, etc. Any ideas for me to check?
- Fixed with camera reset

3. Using an ETTL flash/trigger disables Exposure Simulation. Is there a work around for this? When shooting for ambient and flash mixed this is and inconvenience. Right now I setup the shot with the trigger off then turn it on. Its a bit clunky solve.

4. Shooting tethered in a studio setting the camera with throw up the over-heating warning after about 30 minutes or so. Should I be concerned with the high temp damaging the camera or adversely effecting the image quality? Everything seems fine shooting stills.
- Fixed with firmware 1.1.0

Thanks for reading through this if you've made it this far. Any insight you could share will be appreciated.

The white thermometer icon displaying is an indication by Canon that "image quality of still photos will decline".

Which icon were you seeing displayed during your tethered studio shoot?

It would be interesting to

1. set a very high ISO and take a shot in low light with a cold camera,
   
2. and the after the camera is flashing the overheat warning (white thermometer) take another shot in the same low light with the hot camera,
   
3. and then compare the noise content of the two images.
   

It seems to be just the red icon - right away. This has happened every time I've done a studio shoot and I haven't noticed the white icon at all.

So do I understand correctly, that after 30 minutes of tethered shooting, the red thermometer icon, every time (not literally 'right away' as you just stated, but) more like your opening post? and no appearance ever of the white icon?

Sorry. Right away as in skipping the white icon and going directly to red.

Thanks.

Holy Crapola

O hope you are doing something wrong....This IS BS if true

Were you running the camera in live view the whole time?
I imagine that could set off the over heat warning.
Did the camera also shut down, or keep running?

100% liveview. Camera didn’t shutdown and was still performing fine. Body was warm to the touch at the grip but not hot by any stretch.

Btw, this is a frequent workflow I use and I’ve logged hundreds of hours shooting this way with my 5D mk 4.

So the unit is RED thermometer, which means it is 'more serious' than the white thermometer would indicate. In that event, following the test procedure that i outlined in my Post 2 would still be very revelevant...to get concrete examples of the 'increased noise' that Canon advises about. That is of great interest to umphotography in his decision about getting an R5 for his wedding coverage work.
I realize that your studio work likely involves the use of sufficient artificial lighting whose placement and intensity suit your needs for that client. But in view of white thermometer = 'increased noise images' per Canon, it would be useful to know to know just how much degradation.

Mac Daddy, I would suggest you ask R5 users for help in the R5 thread, or CPS if you know a rep.

I've done thousands of hours with a 5DS shooting the same way, the cameras would get warm, but never actually over heat.

But there is a known over heat issue shooting video with the R5, since Live View is basically shooting video, I wonder if your problem is related.

If your working at 100 ISO I doubt you'll see any impact on image quality.
But the only way to find out would be to test it.

The rear LCD is a greater source of internal heat than the CF express card, that LCD controller on the back plate seems to generate alot of heat.

Is it OK to just copy/paste my original post here to that thread?

I dont shoot this way and run live view for 30 minutes. I dont use live view all that much.... But I can see why a read heat warn light would come on considering the way canon has limited video functions on this camera. Wondering if you can tether with a cable or wifi someway and see if the heat warn light still comes on...again...Not Good. especially if its a normal way of shooting on the 5D4.. I would be more concerned with the following

1- heat damage to camera. Red lights tell me its time to turn them off
2- affects on images captured. You should have images captured before the red light went on and images captured after.....was there any image deterioration from a comparison stand point

lastly- you have reported and so has Moppie with the 5Ds - you guys shoot this way with no problems in the past and now, all of a sudden...You cant.....the question is WHY ?? If the 5Ds is able to shoot this way, it tells me more and more.....this overheat situation is bogus and its in the programming and software

THIS IS WHY- im not about to buy right now. I need more guys to shoot with this thing at weddings and events.....proof is in the pudding....if this thing turns on red warn lights at weddings......Thats not gonna fly and canon will have a major mess on their hands

I will test it out. I'll post my findings here probably sometime tomorrow.
