A few photos with the Sigma 180 Macro and Canon 40d

I finally had time to fix some shots done with the Sigma 180 Macro April 25 in Varaita valley.
I must say that also hides qualities as a portrait lens and I was very surprised having always used to take pictures of flowers and insects. Below I have posted a picture made ​​my girlfriend with a 100% crop to understand why I was amazed.
These few clicks.
