I'm posting this forum to tank people that have helped me with their comments in thisthread. And also to show the photos resulting from it.
As I said in the forum above I went to shoot the Vodafone Freestyle MX Lisbon. I was worried because my fast lenses are a 50mm f1.8 and the 105mm f2.8, and I thought that my tele (70-300mm f4-5.6) was useless in such situation.
So there I was, shooting for a magazine with my poor equipment. I shoot with 2 D70 and I've mounted the 105mm and the kit (18-70) lens. When I got near the pit I saw that I was really close and even the 105mm got me very near the jump ramp. Tooke some test shoots that seemed ok and I got ready. I began to shoot with auto iso, sutter priority at 1/250 sec and continuous servo focusing (that I'm not very used too). The images where soft/out of focus. I thought that it was from the focus and changed to single servo AF, because if I can recall correctly even when it focus, on moving subject, it keeps traking the subject. But the softness still ocurred. I was not happy and tryed to do some fast shooting, at 1/500 and 1/620 sec, and the problem seemed to be gone! I just underestimated the velocity of the motorbikes I guess.
So for me there are a few lessons to learn: try to shoot as close to 1/1000 as I can in this kind of moorsports; the buffer of the D70 sucks when you shoot raw. I was on continuos shooting. I didn't felt that 3 frams per second very limitative but the buffer only let me take 4 or 5 photos at that speed and then it just slows down. And I use eFilm Pro 1GB 40x memory cards! hope that the D200 have a bigger buffer.; third - I'm absolutely converted to raw, because the control over exposure is the best. The maloraty of the images where dome at iso 1600 and after a few small steps they look very good.
know enough talk and let's see some photos. Just converted raw in to jpeg (RawShooters), open in photoshop for Noise Ninja in the iso 1600 ones and then resized with bicubic sharper.
Hope you'll enjoy.
