I have a 6P and a Bobo VR Z3 and it fits perfect when not in a case. Lenses are pretty big and you get focus and PD control. A bluetooth remote is recommended though. I've added some foam weatherstripping under the existing padding (which is ample enough for most people) and because of the way they attach the existing padding you can't tell there's extra under it.
EDIT: I DO NOT recommend those little black keychain bluetooth remotes. They are extremely cheap and difficult to work with.
This is what I got and the controller is really functional... they don't mention it has shutter and music controls on the flip side of the remote.
If you read reviews on that page, make sure it's for the particular model listed since there's a bunch mixed in that are for a totally different model.
