I've gotten the opportunity to shoot pro hockey games. My current gear doesn't cut it:
Nikon D70
Nikon 18-70mm F/3.5-4.5 Kit lens
Nikon 70-300mm F/4-5.6 D
Nikon 50mm 1.8D
Monopod
From where i'm positioned, I found that 200mm is the best focal length to shoot at. I had to shoot between ISO 640 - 800 in order to get a fast enough shutter to stop most of the action, but a lot of my shots still had some blur. My camera is pretty old and has low burst mode, no live preview, and no video (not important for this, but a nice feature to have).
I'm between a D5100 or D7000 or a new VR zoom lens.
Anyone have any suggestions?
