I am awaiting shipment of my H4 black and already thinking how to fully exploit its 4k capabilities.
Since it is my secondary camera (1st: epl5+10bar housing on a tray, which the gopro will also share), I am reluctant to spend a lot and also want to keep size reasonable (sorry, no 5" SPL dome neither a largish DeepPro housing).
First question: is there a dome+diopter (latter for sharpness/close focus, like the Deeppro's dome) combination that could serve the stock lens?
Alternatively, is there a wet lens, that substitute a decent dome port and de-blur the edges? Instead of the dedicated gopro close-up and wide lenses (UCL-G165 & UFL-G140) could someone use "normal" wet lenses? (e.g. I have a ucl-165 for macro)
A bit further related but I found this interesting - where are wet addon lenses in this picture? Better or worse than domes?
As a side project I plan to upgrade the stock gopro lens to a narrower and better one (around 3.5mm). How would a narrower lens behind the stock flat port behave with an Inon uwl/ufl wide lens?
