Fair call, Drew.
One of the big issues of FF digital remains corner image quality (sharpness and vignetting), particularly with CFWA with rectilinear lenses. I guess I wanted to say that these first images might not best to judge it on - having looked at them and seen poor corner sharpness I wanted to check the video for clues as to why. I guess my point is don't right off the D3 just yet - as these shots were not taken with an ideal setup. I just found a geeky way to check the facts.
According to my friends at Ocean Optics - Tom Peschak is using a Subal D3 on the Save Our Seas trip to Aldabra at that moment. Although there is nothing about it on their blog:
Sorry Alex, didn't mean to out you as a geek. ![]()
And having dived there, the conditions are not difficult, just different. Cold water diving requires a different setup routine, and those who do it regularly don't see it as difficult.
Now you want difficult, try ice diving with rebreathers on in a hole that's refreezing in the Antartic. I wish I could release pictures but that is hardcore.
