SAF with EM-5, 75-300 hand-held, 4fps from the beach, no pre-focus, just letting the camera get on with the job. The boats are coming toward me at greater than 50mph.

Your DOF at f6-f8 is like a FF DSLR at f12-f16.

The DOF is so big you almost can't miss focus.

Do you carry an FF and a 500-600mm lens normally?

If not then how are you going to get those shots with nice shallow DOF?

No, I carry a 300mm f2.8 lens for sports, as well as a 70-200mm f2.8.

My DOF at 90ft with the 300mm is 4.61ft at f2.8

The OP's DOF at 35mm at 90ft is 1713.8 ft at f 2.8

The OP's DOF at 45mm at 90ft is 74.8 ft at f1.8

For those of you saying "we can stick some fast glass on too for seperation", have you ever looked at a DOF calculator?
