Rodeo. 600mm lens on tripod with gimbal head 300mm lens on tripod with gimbal head 70-200 hand held Nikon D5 AF-C 1/2000 t0 1/3200 F/2.8 to 7.1 focus is not sharp. I strive to keep the focus point on the face or upper body. Alas, I have a hard time doing this, as I am shooting, the focus point appears where I want it but when viewed, the focus pt. will be off the subject. Something is wrong with my technique and I don't know what it is. What am I doing wrong?
