Alllright, race season is coming up, and I am looking for a way to take better pictures. Primarily, faster pictures would be nice! At the track, flash is hard to use, becasue it lights up the dirt floating through the air. So, max aperture is critical. I currently ONLY shoot with my 70-200 2.8, at 2.8. Currently, I also shoot at the wider end of that focall ength, between 70-100mm primarily. So, 85mm would be a fine focal length. Another fact...I use AI servo a LOT, so I need a good, accurate, fast-focusing lens. Questions: Does the 85mm 1.8 have a fast, accurate focus? Has anyone used the 85mm 1.8 for action photos? What type of shutter speed increase would I be looking at? For instance... if the ambient light provided 1/60 at f/2.8, ISO 1600... whatabouts would the shutter speed be at f/1.8 and ISO 1600? Is the 85mm sharp at 1.8? If you have experience, let me know! Thanks!
