I have a Sony A6300 on a Seafrogs housing.   Primarily doing wide angle 4K videos with a Sigma 19mm and dome.   But occasionally I get stuck with macro specific dive sites, so I will switch to a more appropriate lense.  The lense choices I have that fits in the housing is Sony 30mm macro, Sony 16-50mm kit and Sigma 60mm.


Sony 30mm macro has too short working distance.  Sony 16-50mm have quite poor detail.  So I'm looking at the Sigma 60mm.  The stock magnification ratio is 1:7 which is pretty bad.  So I'm aiming for a macro diopter that will get it closer to 1:2 ratio.    I'll be shooting mainly nudibranch, pipefish and maybe pygmy seahorse.  Hopefully 4K macro videos as well (I have a pair of 5,000 lumen lights)


I'm not sure what diopter to get.. there's so many options.  Nauticam CMC-1, Subsee 10+, Inon, Aquako, iDas is all options.   I'm not particularly fussed about getting the absolutely best magnification..  ease of use and image quality are more important factors.


So what do you think ?
