I see Gudge also uses a Tokina 12-24.
Rarely used underwater since I got the 10-17 and never with the 7D in the Nauticam
So my question to Gudge ( or others ), is the 12-24 Tokina satisfactory in a Nauticam 7D for non-posed diver shots ?
No zoom gear available yet (but is listed on
Canon Port Chart), I'll give it a go and tell you how it goes when a zoom gear becomes available. However, don't hold your breath, my priority order for getting zoom gears is Tokina 10-17 on a 1.4X teleconverter, Sigma 17-70 and then Tokina 12-24 when they become available.
The 12-24 and 17-70 worked fine for the diver shots you're after with my 20D/40D/50D in Subal housings and I'm using the same Subal extensions and ports for those lenses with my Nauticam.
