Doing more full-day fashion sessions in portrait orientation and my wrist is starting to complain. Thinking about a grip for the A7 IV. The Sony VG-C4EM is about £350, which feels steep for a handle with two batteries in it, and the third-party ones are a fraction of that.
Anyone used both? I mostly care that the portrait-orientation controls work the same as the body and that the sealing isn't a joke. Battery life I don't need, I already carry four.
