I am trying to find where in the R7 Manual it says this, and so far, I have not found it. I did find this note in the Canon EOS R7 Specifications listed (for Europe ) on the following site:
https://www.canon-europe.com/cameras/eos-r7/specifications/
However, I cannot find it in my downloaded R7 users manual. Just curious, but I really would like to know about this spec. There are A LOT of R7 users who have an RF 100-500 L lens on their R7!! Are we all running the risk of damaging something??
Also, I am honestly a big confused about what Canon means with this note. It says ", ..total camera mount capacity for camera, lens, microphone.....," should not exceed 1 kg. That sounds like they are referring to something other that the lens mount being the limiting factor. Are they referring to the tripod mount on the bottom of the camera????
Given that the lens weighs substantially more than the camera, I plan on attaching a strap to the lens foot, as others on here have done. But, I still wonder just exactly what Canon meant.
