Sigma 20mm F-1.4 prime on 5Ds/SEACAM/Superdome

19 June 2016 - 09:37 AM

I taught my annual Digital Master class in Key Largo last week, and having six days of local diving provided a bit of time to test new gear.  One item of significance was the new Sigma 20mm F-1.4 prime wide angle.  I shot it on a Canon 5Ds, SEACAM housing, Superdome, and 57.5mm port extension.  This is the same one I use for my 16-35mm lens.  I did not obsess over what port extension would put me in exact nodal point of the lens.  Rather, this is simply plug and play with gear I had easily at hand.  Here are the results:

In that this lens is Sigma, it can work either Nikon or Canon.  I find great potential here and bring it to your collective attention due to collective angst over poor corner resolution in many wide angle optics used UW.

Housing has s6 bulkheads, ready to accept Seacam strobes or s6 cables on other brand strobes,  and also offers remote socket with cable inside housing to camera.  

No scratches on lcd monitor - a little wear and tear on the camera ; a little wear and tear on the housing.
