@bghazzal If you're doing exclusively macro, I think a dedicated macro is the way to go (maybe Zeiss Touit 50mm - 75mm FF equivalent), plus a CMC-2 (easier to work with) and CMC-1 (more magnification) - or equivalents. The 16-50mm would give more flexibility if you use a wet wide lens and close up lenses, but it's very pedestrian for close focusing on its own, unlike the FF 20-70mm or Olympus' 12-40/45 lenses. The 90 macro on APS-c is a 135mm FF equivalent - a bit unwieldy and tight with its narrow angle of view - probably not good for BW. I have a FF A7c and a 90 macro. Had and sold the Sony 50 macro. Looking to try a Zeiss Touit 50 macro on an APS-c body in the future. Probably the A6700. I traveled with the FF Sony 50 macro, which worked okay with the A7c in terms of locking on and tracking for general photos. The combo did not work well for me with BW. I was autofocusing, locking and tracking - but the photographer - or the combo - was too slow. Manual focusing with both the Sony and Zeiss may be a chore with their relatively long throws (turn, turn, turn). I've seen pretty good FF 90 macro BW, but I haven't tried BW with that combo. You'd think, living in Hawaii, I would have more opportunities to do BW, but my time in the water is limited by personal circumstances.

@Davide DB Any opinions on using the WWL for video? I think I saw a post where you mentioned wobbles at depth.

I think Sony's autofocus is really something. Amazingly sticky tracking once it's locked on. The 10-20mm or older 10-18 may be good behind a dome. 90 is a bit long unless you're exclusively shooting creatures <20mm, so the Zeiss Touit 50 macro may be the winner.

It has a reputation for slow focusing. On newer bodies, once it's locked on, it tracks pretty well.

Very nice. And rock steady!

Nicely done @Dave_Hicks !

That's very cool. I wonder if it will work with the A7Cr or A7C II? Thanks!

@PEPhoto84 Welcome aboard!

We can live only so long without facts and the search for truth. Otherwise it's a head-long dive into the metaphorical abyss.

Thanks for that Ben. Always well researched and thoughtful. I did my first BW dive from the Smiling Seashorse in the Andaman Sea. This was in February, and I was a disaster. I had my Sony A7c and a Sony 50mm macro (a bit short and slow).

That's messed up.

Looks great!

"High color rendering lights" -- which current brands fit this picture? Also, I'm a bit annoyed that Minemizu-san copyrighted the term Black Water Dive.

$12,500! I didn't get that for my left kidney.

That hummingbird looks fine, fine.

Thanks @RomiK I thought of it myself. 😉

I, too, agree. And let's not forget video editiing software - a bit easier than splicing and taping.

You can shoot the 16-35 wide open. You may end up with, how do you say, artistic renderings. 😉

The Sony 20-70mm covers a good range on full frame, but likely not a good fit for APS-c. It would be a 30mm to 105mm equivalent - not wide enough and not close focusing enough to make it worth your while.

@John Pierce Welcome home!

Pretty much every modern mirrorless camera can do both, but it's a question of whether or not the manufacturer could mate cutting edge performance and price. You just have to decide which system you want to marry. Lenses gets into a whole other realm of discussion. There are lots of opinions regarding this, and even on whether or not Nauticam's wet lenses are the way to go. The 1650 and WWL seems a good choice. Very good performance. Small enough (though smaller and lighter would be desirable). Others would argue that the WACP lenses are the way to go, but these are more expensive. Another plus for WWL lenses is that they pop up for sale with some regularity.
