Has anyone else noticed the lens on their RF mount Canon moving focus, even when in manual focus mode? I found that, even when the camera is "OFF", opening up and closing the cover for the memory card slots on my R7 causes the lens focusing mechanism to do a quick in-out motion. I have not done any imaging with my R7 yet or I probably would have noticed and been upset by these earlier than just yesterday (I've had it about 4 months). I've tried setting the lens and body to manual, auto, turning off 'retract lens on shutdown', turning off 'close shutter at shutdown', tried it with the camera on and off. always the same. Now I'm wondering what other setting changes on the camera could cause the lens to actuate when I don't want it moving even a hair.
I could see this messing up frame stacking and calibration frames, though everything is 'by-wire', so maybe it is going back to EXACTLY where it was before? It just started to worry me and wondered if anyone has had experience with this and noticed any degradation in your imaging work flow. My previous T5i and my current 6D mk ii don't do this. I get the little LED blinks, but that is it. No worries about carefully changing memory cards (or batteries or anything else for that matter) and maintaining the same optics settings.
