Been trying to digest the information available on the internet about the Nauticam WACP-C and WWL-1B for the Sony system.

I currently shoot with a Szabo converted Nikonos RS13 fisheye which absolutely blows my mind in regards to it's performance, but I'm hoping to pair it with something not quite as wide that can zoom underwater to allow for a different perspective.

Heading to Niue next year for some whale swims and looking for an option which allows tighter shots of the whales with a more rectilinear look to them.

My options seem to be:

• Sony 16-35mm f/2.8 GM ii (which I already own) behind a glass dome

• Nauticam WACP-C paired with the 28-60mm

• Nauticam WWL-1B paired with the 28-60mm

My biggest concerns about them are:

• 16-35 behind dome: Soft corners.

• WACP-C: flares badly when shooting into the sun.

• WWL-1B: needs burping upon entry to water, which for live drops with some megafauna means missing the shot.

Has anyone got any thoughts on these options? If they were to be ranked based on sharpness, zoom range and overall image quality, which one wins ?

I know that my best bet would be the WACP1, but it's just too big to travel with all of my other above water photo gear unfortunately, so I'm leaving it out of the conversation at the moment.

I have the WWL-C (pretty much the same as the B) and while i do usually burp it I sometimes forget to. I have never noticed any defects in the photos from bubbles. They are there floating at the top but don't seem to be in the frame at all.

I dove it yesterday and forgot to burp. No bubbles here:

Great to know !

I do wonder if that would be a different story when freediving however?

Perhaps on scuba it's not a problem as the depth compresses the bubbles and/or gives them time to release themselves?

Have you tried this setup whilst snorkeling/freediving on the surface ?

Mine doesn't need a burp screwed directly to the port (WWL-1). I don't think the bayonet mount is particularly water tight.
