I hesitated a lot, I who wanted to invest in a wide angle, 10 mm? 22 mm? ... Because of excessive distortions and some accounts, (I'm not pro) I finally returned to base 18-55 (mine was broken). Ultimately it's great, it satisfies me and meet my expectations, and super quiet, fast, focus is perfect (compared to the old I had)! Later I will invest in other ranges of large angles, for now I am content to that one. For that price very good investment!
