As we discuss a lot of things on NRF, I thought it might be fun to see what opinions folks have regarding motorsports photography. And, some may put up images to demonstrate a point, but let's not just make this a bunch of images.
To start, the motorcycles....my experience suggests what I like, and this is about all it is about as to our preferences, is to see the rider, bike, rather crisply, yet have some suggestion of motion. So, 1/500 sec or even faster for some settings, or if more motion is desired, I will go as low as 1/250. My capture rate is poor below 1/250 sec.
Equipment, 70-200mm f/2.8 on a D4, 400mm f/2.8 plus teleconverters as needed, and for special effects, a shorter lens panned, with the vehicles as close as possible...even to a 10.5mm fisheye.
One to demonstrate why I like a fairly fast shutter:
Note the lens is an old 80.0-400.0 mm f/4.5-5.6
