Great that typhoon Ruby isn't as destructive as initially feared. It was actually mostly sunny here in La Union this whole Sunday (December 7th), and surfers were having a field day riding the larger-than-usual waves.
Here's a 5-frame burst from my old, trusty tele-action combo. Looks like my 1D4's AF still works well, perhaps almost as good as the 7D2.
