All these shots were taken with a Sigma 120-400mm Super Telephoto, Shutter speed around 200-125th of a sec. Most shots were in poor light so I am quite surprised by the results I achieved with this lens. I used flash for a few shots as fill light only and kept it on about 1/4 power. I only purchased the lens that afternoon and still need to learn how to get the best from it. Anyway these are the better shots. I kept one poorly focused shot because it shows the bike bottomed out with dirt flying from under the front guard (rider 33 image No 9050).
