I've always used RRS plates and brackets on various cameras, up to and including the BA72-L on the A7r2. But, starting with the BA7R2 (also for the A7r2) they've gone for plates extending all the way across the grip, requiring the removal and reinstallation of the battery door and adding unnecessary weight and bulk. I can live with a few extra grams, but don't particularly like the idea of having to move the battery door off the camera and would prefer something that either didn't extend over the grip and battery door, or allowed the battery door to open through it.
Any experiences with the plates requiring the relocation of the battery door?
Does the BA72-L still fit the A7r3/A9, or is it too small and/or block the cable ports?
Any other L-brackets for the A7r3 worth recommending? They need to fit RRS lever clamps and not block access to the ports.
