I bought this wide zoom it a few weeks ago. And I can say I'm really happy. It provides the angles previously unattainable for me and my Canon EOS 70D + 18-135mm. A new way to look and see the world. It can be used to make fantastic skies, unusual angles and unusual perspectives. Pictured interior architecture it works miracles. And on festive occasions it helps to be in the heart of the action and atmosphere. Finally, for selfies is unbeatable, compared to my 18-135mm which is a bit tight, the 10-18mm can see the portrait and the scene around perfectly. Basically, I'm really happy with this purchase. Its price makes it unbeatable compared to 10-22mm for example.
