I have read that the A7rii uses magnets for its image stabilization feature. I have the MagMount system that features a very strong rare-earth magnet to allow you to quickly mount and dismount your camera. It actually worked pretty good with my other camera but I have been a little worried using it on my A7rii. I only use this on my walking stick for additional stability when I am hiking around and not on my tripod. Here is a link to the page (TechTrek Mag Mount) if you need more info on the camera mount system.
Will this mount damage or cause issues with my camera? I am just worried about the magnet somehow messing up the image stabilization.
