Just testing out the 10-20mm 3.5

Wide open not sharp at all but of course stopping the aperture down the images start to improve more and more.

But I'm really enjoying my Sigma "arsenal":
70-200mm 2.8 OS
17-50mm 2.8
And this 10-20mm 3.5

P/S: The last of photo was done with the 70-200, but I forgot to turn the OS off.
:/

Cheers!
