I was wandering what will be the problem using the 8-15mm lens (at 15mm) behind the Nauticam 180mm wide angle port.
I am using the Canon 5D mk iv with the 16-35mm mkiii with a 80mm extension and the 180mm port with good results.
I tried using the 8-15 behind the same port without any extensions and was pleasantly surprised.
I was told that the 1800 port is basically a cat-off of the 230mm port which is the recommended port for both the 16-35 and for the 8-15.
If this is the case - what may prevent the 180 from performing as well as the 230mm?
Attaching a photo taken with this setup. turtle photo edited by booting exposure, Freedivers not touched.
Happy to provide Raw files.
I wonder if it will even work at 8mm with the port shade removed...
Thank you for your input.
