No, I didn't walk out with it yet although it's quite a good deal since the price has went down quite a bit. I have tried couples of shot in the store, it looks okay if shooting objects with ISO 800 or above (like the photo in this post). However when I used ISO 800 to 1600 to shoot portraits, there is terrible pruple and red shift, and the color of the face is totally terrible and the color shfit has gone for ISO400 and 200. I am still considering either to get the DP3 or a new lense for 645d, so let me cool down first before make my final decison
