Great look, feel some getting used to

Incredible sharpness, very nice contrast and good resolution. In the price range, the lens is certainly not beat. Have the opportunity to compare various expensive Canon lenses such. B. EF 17-40 L (at VF), Tamron 10-24mm, and 12-14mm Tokina (for APS-C). In the corners there is clearly sharper and also the Wide-distortion are excellently minimized. Of the other dream. These low weight, fine. Optimal traveling.

The deduction of points there for the strange catch mechanism. To enable it, you have to first time "snap" the lens. That's a bit as if the device has two power switch.

I personally recognize on the monitor at the end hardly what. In 11mm position, things are just tiny But that is not the fault of the lens but only my subjective impression.

Otherwise strong buy recommendation.
