This is how you downgrade the firmware on a Canon camera

1. One thing I noticed is that it now matters more if its animal or people AF. While with the older firmare it didn't really matter.
   
   Just a few day ago I told my model "Odd, you don't seem to have a face, ah its because you are not a cat (while checking AF settings and switching to people)".

2. I downgraded mine using this method (option 1) and it’s a lot better. I re-upgraded to 1.5.0 using a fresh download and it seemed much better, but 1.4.0 is still quite a bit better at finding and tracking.

3. You can usually downgrade with EOS Utility 3. Just click "Firmware update", pick the older firmware, and you're good to go. I did it several times with my R6.

4. So maybe I'm not crazy after all...
   
   On the R6 with 1.5.0, I thought I was having to tap the touchscreen a lot more to tell the camera where to focus while shooting video of my daughter. 1.4.0 seemed to track her much better. I didn't do extensive testing or anything, and I tend not to shoot much video, but Christmas morning footage was more of a struggle to keep in focus than I had expected.

   Yes, but you can’t do it that way with the R5.

8. I just tried it with my main r5 and option 1 worked great (as I'm typing I'm downgrading the firmware on my backup r5 now
   eos utility will not work for the r5 but I feel better now having my firmware back a camera fully working the way I want it to work
   kh camera saved me $300-400 if I had sent it in too canon cps platinum in VA
   if you own an r5 or r6 don't upgrade your firmware to 1.5.0 till canon actually fixes and addresses these af problems it brings
   just make sure you upgrade your lens firmware on all your rf glass through asap "a lot of folks fail to update their lens firmware"

11. I upgraded my R5 to 1.5.0 and immediately had autofocus issues. Went online with Canon and they suggested resetting the camera which helped, but still was having focus issues. FInally, I re-downloaded the firmware upgrade and "re-upgraded" and things seem to be working ok now. Want to be there will be a 1.6.0 soon?

12. I urge everyone to let Canon know if you have issues, the only way anything will get done.

14. When I have my AF set wide open to select faces and eyes 1.5 has a harder time getting a face or eye. However, with AF pt set for single point with Face/eye detection it grabs on just fine and stays attached better than 1.4.

15. A number of people on the facebook "Canon R5 Shooters" group have been posting about this for some time (and lockups). They haven't been able to replicate the problems across a bunch of users yet although many seem to be using BBF and holding the shutter down for a period of time seems to create more lockups.
    I haven't had any issues with 1.5

16. Have not noticed a (negative) difference with 1.5 on the R6. Too darn cold to try the car AF. I do sort of notice what someone else said, that it makes a bigger difference now whether you have Human or Animal set. There is also a no priority setting, IIRC, which may actually be useful now.

    Oh okay, sorry, I wasn't aware of that

18. reported again

    Given your posting history, I would not expect the mods to take any action on your reporting. Sort of a pot calling the kettle black thing.

19. I did a shoot last week with my R6 and RF 24 – 70 f/2.8 lens and experienced unexpected poor autofocus issues I put this down to the low light after updating to the latest software prior.
    
    It was strange, in an easy fashion type shoot with one static female model, I struggled all shoot with eye auto focus. The apartment was low lite and with no model lighting on my AD200’s so I put this down to low light, but AF was noticeably poorer than previous shoots.
    
    I did wonder at the time re the latest firmware update, I had installed pre shooting. I got the shoot done and on my PC the images are pleasantly sharp, but the camera struggled all through the shoot, with me constantly having to focus and re compose to get the servo AF to find my models eye, unlike previous shoots.
    
    Normally I wait some time before updating firmware, in case of bugs or errors but on this occasion, I’d heard no different in reports re the latest firmware, so I updated my R6. I was genuinely disappointed with the performance of AF on my last shoot, how can Canon get this wrong! :mad:
