This is most excellent news! I was thinking it would fit. Good to know. The 30mm macro may also fit? He doesn’t have the special gear needed to flip the macro switch mid-dive and I’m not a fan of $800+ to add it. I prefer to dive/photo with purpose rather than a do-everything approach.

The 30mm macro is limited to about 0.5x for practical purposes, min focus of 1:1 is close to right on the port glass and hard to achieve and light. The 60mm macro is the best option IMO, the Pany 45mm is also a possibility, but the lens will probably cost more. If you want only one macro lens for me 60mm > 45mm > 30mm. The only downside of the 60mm is you have to backup quite a bit for bigger subjects.
