I just came back from spending a weekend with the D3, the D300 and the 14-24 F:2,8
As I mentionned in a previous post there is no provision for rear filter and the rear element does a lot of moving around, i'm sure there is a way to attach my beloved magic filter to the back, but it would have to be done in such a secure way as not to fly away into the shutter with the disastrous consequence one can imagine.
I tested the lens against my prime Nikkor 14mm and there is quite an improvement on the 14-24, light falloff is noticeable on the prime 14mm the moment you put both side by side with the zoom results. I'm pretty confident this lens will prove popular, now as soon as I can get the D3 housing i'll test it u/w on a grid to see the edge performance.
BTW the D3 fit in the front of our D2x housing with all the front controls functional except the metering selector, so i'll need to talk to engineering and see if a retrofit package can be made for the D2x, that would help lower the cost of migrating to the D3 (which is the most amazing camera i've had the oportunity to work with in 35 years of handling, selling and repairing cameras for a living
), underwater available light photography will never be the same from now on.
The Megadome will ship from now on with the wider throat to accept this baby, here is a shot of a D3 in a housing with the 14-24, megadome and extension.
and one set up with the D2x
