I'm kitting up my Sony A7SIII hoping that I can resume my diving trips early next year after a very long break due to COVID-19, and narrowed down to two options:
1) The Sony FE 12-24mm F/2.8 GM or Sony FE 14mm F/1.8 GM with the Nauticam 230mm optical glass dome port. I'm planning to get either of these lenses for astrophotography anyway.
2) The Sony FE28-60mm F/4-5.6 with the WWL-1 and CMC-1, both of which I already own when I was shooting on the M43 system. This setup will of course be the most versatile especially diving in places like Raja Ampat or Komodo where there are wide-angle and macro subjects to shoot on almost every dive.
Besides the cost difference between the two options, which is really the cost of the 230mm dome port and not an issue for me, the main differences are the ability to do split shots with option 1, which is useful as I'm hoping to do more snorkeling to swim with orcas, humpback whales, etc. But I'll have to deal with the bulk when traveling (I travel for all my dives since there's no place to dive in Singapore) and I understand that the 230mm dome port is huge. I read somewhere in the forum that you travel with the Sony 12-24mm (can't remember if it's the F/2.8 GM or the F/4 G) and a 230mm dome port. So I'm wondering what is/are the main/overriding reason/s that you settled on this setup instead of using the WWL-1/B?
For solely macro shoot, I already have the Sony FE 90mm F/2.8 Macro G so I can just decide whether to dive with a wide-angle or macro setup depending on the dive spot, a compromise that many underwater photographers or videographers always need to make.
I have read your reviews "Sony's FE 12-14mm F/4 G lens" (UwP105), "Nauticam WWL-1 & Sony Full Frame" (UwP114), "Nauticam WWL-1B Review" (UwP120) which you discusses the use with the Sony FE28-60mm F/4-5.6 and "Sony FE 14mm F/1.8 GM lens" (UwP122). I don't recall you ever reviewing the Sony FE 12-24mm F/2.8 GM. All these reviews are very informative and helpful.
Thanks in advance,
