Thank you all so much for the replies! I was in a bit of a rush and went ahead with my own design after @Isaac Szabo shared the tooth count. It's a single-piece gear and seems to be working well so far. I haven’t tested it underwater yet, but I’ve made similar designs before for my m4/3 lenses, and those worked great.Zoom2860.stl

I'm planning to 3D print a zoom gear for the Sony 28-60mm lens. Does anyone know how many teeth the Nauticam N100 port system uses for zoom gear?

Hello, I currently own an Olympus OM-D E-M1 Mark II in a Nauticam housing. While I’m happy with the stills, the video performance has been disappointing, so I’m looking to upgrade. Ideally, I’d like to stay within the M4/3 format to reuse my existing ports and lenses. In that case, I’m considering the Panasonic GH5, or possibly a more video-focused option like the GH5s or Blackmagic 4K. In theory, I could stretch my budget to go full-frame with something from Canon or Sony, but the bulk and complexity of a full-frame rig underwater is a bit intimidating. I plan to use the new setup primarily for video on warm-water cave dives and cold-water deep dives, often with CCR and DPV. What would you recommend? Thank you, Vitaly
