I used a gopro 4 black before and have an Inon UWL-G140 for it. Just updated the age old camera with a gopro 13 I wonder what's the best option to fit the lens on the original gopro dive housing? Compatibility with my polarpro filters (basically gopro's stock diving & snorkeling orange/red filers) would be a fantastic plus.

Apparently I got two options: stock Inon SD front mask (haven't found a UK dealer yet): doesn't seem to be polarpro compatible nor has its on provisions for filter.

The Backscatter mount, here it says is compatible with Inon SD lenses (should be verified though). Maybe it doesn't work with the polarpro filters but at least I can buy the backscatter filter inserts.

I hope you can make that work. I haven’t looked into it in a while, but it seemed easiest to go for the Backscatter Flip filters, though there are likely better solutions out there.

Hi TomG,

The AOI adapter is fully compatible with the standard GoPro housing, from 5 to 13. I have one here.

In the box you have several mounts and ADRech states all the lens compatible with that quick release mount:

IIRC latest Inon mount is not compatible (probably they changed it because AOI lens/mounts are cheaper 😉)

Old Inon mount a AOI works flawlessly in all 16:9 formats but they vignette on GoPro full sensor 8:7 format.

Backscatter mount is made by AOI and it's slightly modified to accommodate slide-in filters between the lens and the GoPro housing port. The lens is further away to leave enough space for the filter. I can't tell you if this increases the vignetting issue; I don't think so, but it's probably best to ask Backscatter about it.

! That's a perfectly valid point! Will test that handheld with some makeshift spacers. Also, if the lens is further out than the original optical design suggests, correction might not be as good as intended. Planning to use 4:3 aspect ratio at the highest resolution available.

So the Backscatter and AOI mounts are all compatible with Inon's SD bayonet? That sounds great.

Just send an email to BS and ask them.

Never tried but according to all review and the ADTech website, yes.

@GTom AOI / Inon lens and adapters are backwards compatible on gopro (original case)

If you not in Rush, i would wait for the new AIO UH-ACT universal case for Action cameras with lens adapter built-in.

I expect the new AOI case to be more expensive than the lens adapters + gopro underwater case.

I would not go filters route.... Dive lights + gopro labs gives you much better results.

Nando, let’s be fair: you don’t know the OP’s local environment or their specific diving habits, so please avoid being so categorical with your advice.

ok

GTom, do you dive/snorkeling shallow? Tropics or temperate water?

For tropics and shallow dives a good filter is enough.

Snorkeling doesnt require any filter while deeper or temperate waters requires lights for sure.

That one looks interesting. Not super hurried but would like to get and test the gear before Summer.

Valid point, Lights are not ideal for some of my favorite targets: underwater landscapes & groups of people. Latter even in the pool might benefit from slight filtering if the subjects scatter 1 to 5 meters from me (subject to loads of testing though).
