I'm going to make photos for a car racing team this season, and although I've done some of it for fun in previous years, the test session we did today clearly showed that I lack skill as well as equipment to do a proper job. To make things worse, the sun disappeared behind a huge, black cloud that covered half of the sky, while the other half was covered in white, so there was too little light and no contrast.
What I also found out was that the D80 is rather useless for this. The AF simply can't handle the speeds (the fastest of the touring cars do 250 kph down the straight). The S5 did much better, but I will need at least 800 and probably 1600 ISO on days like this. That means a D300, right?
I also found out that I don't have enough reach. Even with a 1.4x TC, the 80-200 AF-S was sometimes too short. I have the impression that the Nikkor 80-400 is too slow, and that leaves me with Sigma and Sigma. The 120-300mm f/2.8 would probably be great, also with a TC, but it's too expensive (and it's huge). However, I have the impression that the 100-300mm f/4.0 is very good as well, even with a 1.4x. Does anybody have experience with that lens for motorsports?
Yes, I know.... Nikkor 200-400mm f/4 on a D3, but unfortunately, I can afford neither
Any good advice would be highly appreciated. The season starts in four days. Here's one of today's attempts:
D80 with 80-200mm AF-S and Tamron 1.4x TC @ 180mm, f/4.0 (wide open) and 1/400s
