When the R3 firmware update came out and indicated it quashed a freeze problem, the ears of many R5 owners perked up. And now we have confirmation from multiple people speaking directly to Canon service representatives that they expect a firmware fix to be pushed out for the R5 in the next release.
A Canon service rep stated in an email, “Canon has already acknowledged this phenomenon in question and is now planning to correct the firmware. Once the countermeasure firmware is ready, we will make an announcement on our Web site.”
The R5 freeze issue proved to be rare for most people who experienced it. Opening the battery compartment and closing it successfully resets the camera in a couple seconds. While many forum dwellers attempted to narrow down the settings and accessories that might be involved, the infrequency of the freezes made this very difficult.
1) I have image Review on LCD on
2) I have back button focus
3) I set on one of the back buttons to eye-focus.
Now it freezes if you take a picture, then when it appears on the LCD you press the eye-focus button and the try to take another picture.
If you do that 3-4 times it freezes.
EDIT: ignore that please. I just read some of your posts.
I did not have eye AF issues with 1.5.0 but I shot only static subjects using 24-70 and 85 1.2 indoors.
As far as 1.4 vs 1.5, the tracking of head/eye is better in 1.5 but there is an issue with back button focusing in 1,5, I have three back buttons setup on my R5 and the 'normal' back button seems to be less likely to focus with 1.5.
It does happen once or twice in a 5+ hour event.
Using 1.4. I always wait a few weeks to upgrade when new software is released to hear the complaints.
I hope the Firmware update fixes all of the R5 freezing issues for everyone.
I didn't have any freeze in any firmware release but I believe I had some AF issues lately.
It seems responsive now and the only time it could not focus was USER ERROR (min focusing distance lens setting). Of course in really low light inside the house and with the 100-500 at 7.1 focusing was really slow but this is to be expected I guess (and it worked).
I also tried it with the RF2X and except from an almost dark room (let's not be unreasonable) R5 worked ok on a cloudy day.
It seems to focus in close distance reasonable well (when there are leaves close by and the sensor covers them almost but not fully). At least it worked with great magnification (600-1000mm).
The above do not represent of course 100% of camera's functionality but the basics seem OK.
So 1.4.0 stays for now and I will wait for 1.6.0 to see how I will proceed from there.
