Thanks guys! I like how the cheapest option was recommended. So far I'm thinking 16-35 f4 IS, 24-70 f2.8 II, and maybe the sigma 85mm Art down the road. I'm going to need something for thanksgiving, I've been asked to take pictures. Which one should I get first? By the responses so far its probably going to be the 16-35.
I was trying to take a picture of a flock of small birds. I kept the background in focus perfectly the entire time. Which auto-focus mode would you suggest for BIF and flocks of small birds?
