If one gets a Contax G2 and sets the motor for the 4 frame per second setting can you get good sharp images on a moving subject? Not one where the focus stays the same from frame to frame but where it is moving? Want to photograph wrestling on High School, Collegiate & Freestyle matches & the focus is generally on the eyes but the wrestlers move back & forth and front to back a lot. Will the Contax keep up with them at either the slow or fast setting? "predictive autofocus" often doesn't do well here as the action moves in erratic directions... no real predictive anything at times.
A 90mm lens is just fine for the matside locations I use and I like the sharpness& contrast of the lens I have tried. Don't know if it can do what I need.
