Well, since my other lenses are gone I need to replace them. Unfortunately I don't have $$$ to replace them with the same ones. I can probably only afford 1 lens for the next year or so.
What was stolen: 24-105L, Sigma 50 1.4, Canon 18-55 IS.
What I still have: Canon 50 1.8, Canon 70-300 IS.
What I mainly shoot is my children like so:
I need recommendations for a single lens that can do the job of focusing on fast kids and has decent IQ across the image for occasional landscape shots. I shoot on a 7D with a crop sensor. I would limit the cost to under $600.
