But with 4 stop IS should be OK. I have handheld mine at slower speeds with crisp results. The shot above looks front focused to me.

Just to be clear, I wasn't formally testing the lens. The zoo lies between the camera store and my house, so I stopped by for a few hours just for fun.
As I said, I'll be doing an actual test this weekend; SpyderCheckr, SpyderCube, SpyderLensCal, Manfrotto tripod, the works.
I would go with center weighted averaging and select which focal point you want with that type of shot about 1/200th or so...don;t use a 7D but whaever the equvilant would be...Those are great lenses...if it doesn't do right, send it back to Canon or exchange for a new one which ever would apply...
My old photos(taken around 2005) shot with 10D and 70-200 f/4 (non-IS).
My 1Ds and 70-200 f2.8 had to stay home because I got tired to being the last guy to board the plane and losing the overhead storage.

What difference does the exposure metering method make with regard to focus?
Also, you're not often going to get 1/200 out of an f/4 lens on a cloudy afternoon in the woods in Seattle in January unless you up the ISO quite a bit over ISO 200, and I didn't want to use high ISOs.
