Hello, I'm in de process of ordering an nauticam housing for my sony a6700. I use it with a sigma mc-11, does someone else has this system? Maybe with a zen dp-100? - according to nauticam the zoomgear 19529 is for N100 mount, not for the N85. They haven't tested it so according to nauticam it's not sure it wil work. Is someone using this configuration and with what zoomgear? - and what is the difference between the N85-N120 post adapter I and II (36206 and 36207). I know the 36206 is no longer in production, the 36207 is newer. I can get the 32606 second hand, saves me some money. Is the N85-N120 enough with 50mm, is there a difference between the sigma mc-11 and metabones adapter? Thank you!
