Herons in flight with the 1D4
Jul 7, 2010

Just exploring the behavior of the 1D4's AF at BIFs. So far, I feel that my 1D4's AF is faster and snappier than my 7D's when using f/5.6 lenses (500 f4 + 1.4x, 400 5.6L or 100-400 IS). With f/4 lenses or brighter (bare 500, 400 2.8 with or without a 1.4x TC), I can't see yet much difference in AF speed between my 1D4 and 7D at BIFs. Migrants (mostly water birds) are due to arrive in our islands in a few weeks, and I look forward to shooting the two bodies side-by-side in a target rich environment.

Here are some birds taken yesterday at Manila Bay (Philippines).
