5 out of 5 eggsIncredibly Sharp

Pros: Sharpness, fast AF, color, contrast

Cons: None

Other Thoughts: Agree with the other reviewer RE crops. I'm using this on a trip and with a 7D @ 18MP I get fantastic 100% crops. This is a great landscape lens and I think a great buy if you can deal with primes.
