Looks great! My issue with your product is that I have no idea if I can fit a Tokina 10-17 with a printed focus ring for the a6xxx housing. A good port chart would help your sales I'm sure, I particularly find Ikelite port charts to be useful as they comment on vignetting and other aspects to consider.
Hello! I just bought it with the 16-50mm port but I am unable to remove the port from the housing. Is there any problem if I just leave that O-ring like that and try it in the water?
