Wet lens manufacturing problem? (UFL-G140)

13 March 2015 - 05:37 AM

Is this artifact on the side of the lens OK or is this a manufacturing problem? To me, it looks like an

unfinished sealing...



Depth rating of Inon wet lenses

11 March 2015 - 05:28 AM

I was wondering how deep the wet lenses, containing an air pocket, can go? My gorpo is proud to have a UFL-G140 
and I plan to send it deep either via ROV or during a tech dive. The official depth rating says 60m/200'. Does the lens implode
at (exaggerating) 201'??

Wide converter selection for custom minicam (modded gopro)

01 February 2015 - 12:09 PM

I am planning to add a secondary camera - a modded gopro with a 100°FOV (narrower than stock) lens - to my gear.

To avoid the flat port issues, I am seeking a wide converter - first to provide nice corner IQ then to restore FOV.


Which wide converter shall I try? Inon has a gopro-specific unit (UFL-G140) but that is only available with SD-bayonet

which seems to be impossible to mount on my 3rd party aluminium housing. Besides, the UFL-G140 is obviously designed

for the stock lens, I don't know what it would do with a narrower one.

GoPro dome port or wet lenses - any experience?

29 January 2015 - 07:34 AM

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?
