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.

The chart to which you linked in your Sep. 30 message is dated June. Have you tested more lenses since then? Can you post an updated chart?

I understand that you are only testing lenses from 28mm because wider lenses will vignette with the WACP. However, as previously noted, Nikon has discontinued its 28-70mm lenses and replaced them with 24-70mm lenses which offer significant optical and other improvements. A more modern lens would be an advantage for use outside the housing. The fact that it would vignette at its widest setting would pose no obstacle to using it behind the WACP within the 28-70mm range (or even using it wider in situations where losing the corners would not be a problem). Could we have some tests with a lens that is actually currently available? Would also love to see a test of the Sony 28mm f2.8 on a Sony FF behind the WACP. Mahalo.
