Thinking about shooting wildlife or perhaps sports. with C-AF and 10fps. In your experience can you maintain 10fps with a faster lens, say f2.8 compared to say f5.6? If you zoom does that cause 10fps to drop to 6.5fps? If you stop the sequence and start a new sequence in X seconds will the new sequence likely do 10fps? How much time is needed between sequences for the body to be about do do 10 fps again? Has anyone written or seen a good description of the real world tradeoffs between C-AF and 10fps?
