Hello everyone! I would like to try my hand at macro photography using a GoPro Hero 11. I was thinking of purchasing the Inon UCL G55 ZD as a lens:

Inon UCL-G55 ZD Underwater Close-up Lens

and as a mount this:
Kit Doppia Staffa Custodie Fotografia Subacquea con Sfere 25 mm

But I'm still not convinced on the strobe/light to buy. Are there are there relatively cheap lights to start with? I usually dive in lakes but I want to go also in rivers and streams and I also have an holiday planned in the Maldives at Dharavandhoo where I hope I'll find some nudibranchs.
