Nikon D3S video: dark, rain and wind 400mm f/2.8
Wednesday, November 25th, 2009As part of my tests of the Nikon D3S (British Journal, report in December, with additional material by Richard Kilpatrick who is shooting with Nikon on November 25th at a press event) I dragged the £6,000 400mm f/2.8 AF-S IF ED G supertele into the rain as darkness gradually forced the ISO up from a mere 10,000 to the maximum 102,400. The object was make a short video showing rising floodwaters, no threat in our town but still dramatic to watch.
Here’s how it came back from the hour in the rain, a quick wipe down with an oily rag and it was all as good as new. Actually, it needed a thorough drying with the towel then a clean up with a lint free microfibre cloth to remove dust and towelly stuff. The very deep lens shade kept the exposed front element totally dry despite the wind and rain; I just made sure it was never aiming into the wind.
During the shoot, wind noise was a major problem. I locked the microphone to level 2 manual gain, not automatic which would have been a disaster. Many clips had to be shortened, some discarded due to violent wind noise I could not mask. The sheer weight of this combo made lugging it with a decent Slik tripod (pan and tilt head for video) difficult; I drove to the evening location with the rig laid flat on the back seat of the car, but still had to walk several hundred yards for some shots. I wore a Tog24 parka and found that by pulling the fur-lined hood over the camera body I could cut out nearly all the wind noise. I must have looked like a view camera operator with a dark cloth, or something out of Monty Python with my jacket pulled up and the hood over the Nikon!
But, this seemed such a good solution to the wind noise I would consider unzipping the hood from the parka and using it as a baffle in finer weather.
My favourite part of the video is the one with the worst noise, where I was not able to keep the wind away from the direction of shooting – the sequence of the road (flooded by the morning) with headlights, tail lights and cars in rain. This consists of three takes blended with long crossfades. During each take, the manual focus of the 400mm used at near wide open f/3.2 aperture was pulled to bring the moving traffic in and out of focus, and create huge bokeh circles from the lights. This would be impossible with a camcorder and not all that easy with a conventional high-end video kit. The combination of full frame 35mm format and the fast 400mm has enabled a highly effective cinematic technique to succeed on the first time of trying. With some markers on the focus ring, some practice and many more takes the result could have been refined further.
But I was getting very wet and so was the camera!
The first part of the video is all on the 400mm with tripod, with High ISO video enabled. The ‘next morning’ stuff is on the 24-70mm, hand held, locked down to ISO 200 at f/8.
I’m not sure when our final review of the camera will appear in the British Journal, it should be early December.
The video is encoded to best quality 720p from iMovie09, and can be best be downloaded and viewed without any YouTube jerkiness at full res if your connection is not good.
