Well reading about how well the accuracy is on the 7d af points, I went out and got this great picture of a Wood Thrush. If I'm wrong please correct me . I was curious about how well it can focus on specific things.
He was in the bushes across the road and I got a great picture. I was using a EF70-200L with 2x converter so quality is not great but still i was able to lock on through the bushes and maintain focus ans if i crop maybe 50% its a great picture to look at. I took 7 pictures all in focus.
This is a 100 cropped picture. Wish i had a 500mm lens now!
As you can see, all the branches around and the one that's in front of him on the backside. TheAF did job quite well
