I’ve written (and routinely update) this article so that (1) it’s easy to refer people with questions about the gear I use, and how I set it up, and (2) I can remember what settings I use, too.

Of the 7,998 photos I took with the 200-600 mm shots in Kruger (excluding those taken with the 1.4x teleconverter, discussed below), 6,930 (87%) were at focal lengths from 404-600 mm. The extra reach over the 100-400 mm was definitely useful, and I used it a lot.

I’ve just been testing and refining my gear configuration for macro, so I thought it’d be useful for Future Simon – and hopefully you too – to write up some notes on underwater macro photography with the Sony A7rIII camera, Sony 90 mm macro lens, and Nauticam NA-A7RIII housing.

I’ve been using the Sony FE 90 mm G OSS macro lens as my go-to underwater macro photography lens since late 2018. I really enjoy using it – with the exception of poor autofocus in low light underwater using the Sony A7rIII, which I rant about in great detail here.

After a few days on Isabela Island on a wildlife-watching trip (photos to come), we flew over to San Cristobal on a small plane. We wandered down to the “Hammerhead Pier” early the next afternoon and were met by one of the dive guides from the Humboldt Explorer and transferred out to the boat. It was great to see a few familiar faces from past trips, and lots of new ones!
