My nephew has been racing in motocross for several years, but I have not been able to make it out to watch. Last weekend he invited me to come out, and I decided to bring the camera. He was able to work with the organizers, which provided me access inside the fence to post up for images. Below are a few images from the day.
It took a few races to get my settings locked in. I ended up settling on 1/160 shutter speed, ISO100 and let the camera auto set the aperture. I plan on going out again in a few weeks, and will potentially use a faster shutter, maybe 1/200 or 1/250.
