New D4, baptized it in a bit of drizzle at a baseball game a while ago, but decided to really try its weather seal yesterday. I went out to Sanibel Causeway, with Isaac approaching off shore we had about 20-45 kt windows (at a guess), and light to moderate rain.
It was tough to find a good spot, as sand was blowing hard off the beach, so mostly I was at the water's edge as the water blowing hurt less (and would do less damage) than the sand.
I could also only shoot in a limited number of directions; the 200-400 has a great big lens hood that worked great at keeping rain off, provided I did not forget and turn into the wind.
I shot the causeway first (all wind surfers) then moved on to lighthouse point where the kite surfers were (and a whole different wind setup).
The camera performed flawlessly, and a few quick wipes got rid of all the water. The focus performance was terrific, this through wind-blown rain and with the lens itself shaking quite a bit in the wind.
All in all I was very happy to have a professionally sealed camera, and the fast frame rate let me get a few shots just at the point of action I wanted. A very good day.
Here are a few samples. It was a very grey and depressing looking day, I lightened them up and added some saturation. Note that the flat water belies the wind speed, as the wind was blowing from the shore for the kit surfers, and across a small bay for the wind surfers. But the gulls were flying backwards!
All with the D4, 200-400/F4 @ F4, mostly 1/1000th or 1/1200th, ISOs vary between 100 and 300 (I'm starting more and more to use auto-ISO as my "auto" mechanism, and shooting manual otherwise).
