Hey everyone, Sorry if this post is a duplicate. For my scuba trips, I use a Nauticam housing with the WWL-1b and 28-60 mm with my Sony A7IV, which works well. Since I live close to Baja, I do many “seafari” trips like Mag Bay or Mobula Ray types of expeditions. With more fast paced action with shallow free diving, I am not enjoying the wet lens setup at all since the air bubbles do not always readily clear. I would like to have a separate “no wet lens” setup that is more streamlined and conducive for seafaris. I do have a sigma 15mm fisheye lens sitting around. The way I see it is I have the following options: Sigma 15mm with Nauticam 140mm dome WACP-C, it will be bulkier and heavier maybe not as streamlined? Nikonos RS13mm just finding this lens at a reasonable price is difficult, but sounds like an ideal option. Am I missing anything else? Look forward to hearing about folks experiences, thanks in advance. Samir
