Back at Photokina, Tamron announced their intentions to release a new 70-200mm F/2.8 VC lens and they've made good on that promise. I spent some time shooting with the new lens on a fresh-out-of-the-box Canon EOS 6D. All of the images were shot in JPEG mode with standard image settings. Click the links for full-resolution images, but make sure you're on WiFi, as the files are up to 10 MB.
The focus in this photo is on the purpble ball ornament to the left of this frame. The light was coming from a large window to the right of the scene. We'll have to test it in the lab, of course, but right out of the box it seemed pretty sharp.
