I bought the R5 Mark II for my wife a couple of months ago and it's had a few issues:
What do I do?
- Freezes up sometimes when trying to preview photos. Requires removing the battery to resolve.
- When using the RF 100-500 lens and shooting at 500mm F 7.1, it would not auto adjust the aperture when zooming out to 100mm. Other times it worked fine.
- Today if froze up just after turning it on for the first time. No buttons worked. Required removing the batttery to resolve.
What do I do?
- Expect these on a new model and wait for more firmware updates
- Contact Canon for a warranty claim
- Toss it out the car window and buy my wife a Z8 (just kidding)
