When you think it can't get better with Canon, it surely can now! For this price and size there is no contest in the entire market. I dare say. Even the 1/3 macro is very handy and works great with on top flashes like the nissin i40. EDIT: dropped the nissin for ttl. On newer bodies from 80D on.
Price; size; IQ
To bad it is APS-C only; But that is nitpicking for this price
