In Topic: Introducing Nauticamís WACP - The Wide Angle Corrector Port: Discuss Here

Ryan -

It would also be very helpful if you could specify the maximum lens diameter that can be effectively used within the WACP, perhaps using front filter thread size as a proxy, since this is more widely reported on lenses than the actual diameter. The excellent review by Alex and Jason failed to specify if they were using the Nikon 28-70mm f2.8, which has a 77mm filter thread, same as one of Nikon's current 24-70mm f2.8 lenses) or the Nikon 28-70mm f3.5-4.5, which has a filter thread of only 52mm. Some more clarity with regards to the exact limit on the size of lens that could be used would go a long way toward helping us envision the range of lenses that could potentially be used. Thanks. Very excited about the potential of this new tool, and grateful for the R&D effort that Nauticam has put into this.

 

 

Physically smaller diameter lenses are definitely better with corrector ports, which tends to mean using older lenses. The large front elements of the latest generation of lenses would require huge corrector ports to work as well as the older lenses. And as Ryan says these would just be too heavy and too expensive - importantly with very little improvement in image quality - remember it is the port that the bottleneck on image quality, not the lens. 

 

The lenses I tried behind the WACP have been Nikon 28mm f/2.8, Nikon 28-70mm f/3.5-f/4.5 and Sigma 28-70mm f/2.8-f/2.8. I know that Jason Isley also used the Nikon 28mm f/1.8. 

I don't own the Nikon 28-70mm f/2.8-f/2.8 and considered buying one second hand. But speaking with Edward at Nauticam he thought that it might not offer any advantage over the f/3.5-f/4.5 with the WACP - which is actually a sharp lens, despite being small and slow. I will try it one day.

I tried the Sigma 28-70mm f/2.8-f/2.8 with an earlier prototype of the WACP and also send my lens to China for Nauticam to test in the lab with the production WACP. But for luggage allowance reasons I haven't retested in the field.

 

I would like to try more lenses - but the focus thus far has been evaluating the WACP - and it was sensible to all be using the same lenses to do that, rather than introducing another variable. For me the best lens was the 28-70mm f/3.5-f/4.5. 

 

So far the emphasis has been testing the WACP philosophy and I am sure that in the coming months as more people have a chance to shoot it - we will get better information on the best lenses to use.

Do you have any experience with Sony FF/28-70 with WWL-1?

Or we have to wait for WACP.

 

I am not really involved in the Sony mirrorless community, but I am sure lots of people have shot that. I have seen Cheungy Diver shooting the WWL-1 and 28mm back in 2015.

Hi,

Why does Nauticam only recommend Sony to WWL-1?
Why not for Nikon, for Canon?

I couldn't get the WWL-1 to mount close enough to my lens to use it with Nikon with 28-70mm (this was 18 months ago):

The WACP is the solution for this failed attempt!

But with the Sony setup you will be limited to only 130˚ with the WWL-1 or the WACP. You still need a 180˚ fisheye. Also while it is possible to shoot splits with the WWL-1, it is not advisable - as there is water in front and behind it to contend with. Again you want a fisheye and normal dome for that.

I'd love to read a test about the Nauticam Sony A7 II / A9 + 28mm + WWL-1 against WACP, given the price of WWL-1, is one third of WACP.

 

 

Hopefully the WACP will get much more testing soon - I don’t think the WACP has been tested on a Sony yet.

 

During the development of the WACP, I shot a prototype version in the Red Sea that was half way between the WWL-1 and the WACP. On my Nikon this was about a stop better than a dome and a stop worse than the the final WACP. So maybe this is a guide for now.
