I have a Canon 40D. I use 3 different lenses right now. The 2 that are best for car shots are my Sigma 17-70 mm 2.8 wide angle macro and my 70-200 mm 2.8. Both are my favorites. The one of my Camaro was shot with the Canon Rebel XTI (sold to buy the 40D)Those are some nice flames, gives an extra kick to the cars styling. What camera do you use?
