SmallRig 3594 Reviews

Great Product but very specific.

I’m not writing this to bash the product. It’s a great product however if will not fit properly with a third party battery grip. Some doors will not be able to open. I had a A7r IV with a neewer grip, and the battery door and flash sync door couldn’t open and sd card door (wasn’t as issue) couldn’t open fully.

Improvement over V1 design
