優點:
Fast focus, Excellent perfect Quality in its price. A perfect match with Tamron 28-75 XR Di F2.8. Have some samples in my Dcfever album.
缺點:
I had finger plum after taken 700 shots in my Italy trip. Therefore, there is room for improvement of the hand held position on the right. The hand held position should be made with some soft plastic like BG-E3. However, Canon want to earn more money by providing an option of a better and more comfortable hand grip BG-E3.
