Hi everyone, just found this community as I'm in the process of buying my first UW setup. I've been a professional photographer for going on 20 years, but only just started out underwater, been using rented gear, Nauticam and Ikelite thus far. My work's mostly in commercial shoots, so I'll probably need some longer lenses and less fisheye/extreme wide angle than most people use around here. I'll probably go with the Nauticam for my R5 II, as I have a tether solution available for it, but I'm split between the 180 and 230 mm dome. I like that the 180 can work more like a flat port with longer lenses, but the 230 offers more overall sharpness. My ideal lens choices would be the (newish)RF 16-28 2.8 and 28-70 2.8, but obviously neither are in the port charts. Does anyone have experience 3D-printing the focus gears? Don't think the 15-35 L and 24-70 L are in my budget at the moment. I'm also eyeing adapting to EF and getting the 16-35 L and 24-70 L, but the EF port chart only shows the 8.5 " acrylic port for the 24-70. Has anyone used it on the 180 mm port? Is there a reason why it wouldn't work? Definitely don't want acrylic, as my experience with Ikelite had it scratching just by looking at it funny. Thanks so much for any help!
