67mm macro wet lens on GoPro ?

[stepfen]

Out of curiosity, would somehow attaching a M67 diopter in front of a GoPro be any good for macro videos????

I have a photography setup that I've been using for years now consiscting of a Sony A5100 camera in meikon case, with an inon +6 and a Subsee +10 diopter (both M67) and two sea&sea strobes. The said setup is practically limited to macro shots and I am thinking to try things in wide angle and video by moving to a GoPro based setup. But since I am not done yet with macro I don't want to abandone it yet. There are few more nudibranchs in my area that I haven't photographed and God knows what else I might encounter during my next dive after all.

As I was looking at my old setup, thinking what I am going to do with it, I thought that if I could somehow attach the diopter(s) in front of the GoPro I should be able to get some decent macro shots, isn't it?

What might not work is the "digital lenses" that GoPro is using to produce these 16:9 (or even wider) videos, because these combined with a diopter might introduce heavy distortion at the edges. But in GoPro 11 I read that the sensor has an aspect ratio of 8/7 (almost square) and the user has the option to record in this format. That should work pretty nicely with a diopter, isn't it??

Can you think of any other reasons this might not work???

Of course there is also the problem of how to attach these (comparatively huge) lenses in front of a GoPro, but if it works I will think of something. I wonder has anybody tried it?? Any results (good or bad)??

Thanks a lot

Tikanis, Stepfen! Sounds like you're wanting to try to adapt some SLR-type (or similar) lenses to GoPro for macro? I shoot macro with my GoPro and have had pretty good results. I have never used the types of lenses you referred to, but I do use lenses that are designed to work with a GoPro. I have provided a link below. The Backscatter FLIP lenses allow you add an attachment that holds a macro lens allowing you to use the macro lens when you want and then rotate it out of the way to shoot regular wide shots. Backscatter has a 55mm lens and also a +15 attachment that screws onto that if you want that magnification. My experience is it works well.

I also starting using the Flip Filters system on my GP 10. I have the Close Up on one flipper and the +15 Macromate on the other. Happy with the results so far.

The Flip Filters use 55mm threads. You might be able to buy a 55 - 67 adapter and use your lens on the Flip Filters 55mm holder.

Don't know what Gopro you have but the 10 has a "narrow" lens setting that works when using the macro lens.

Actually this Inon M67 Filter Adapter for GoPro HERO9 & GoPro Dive Housing
seems to be exactly what I was talking about... 67mm Lens Adapter for GoPro!!
In the specs though it is described for use with red filters only. Since the diopters are nothing more than a magnifying lens, I don't see why it won't work.
