Sigma 24-70mm f/2.8 -- how sharp?
Well, I took a few minutes today to test this lens against the Nikkor 18-200mm VR II. Here are photos of the Nikon lens box I just took 2.5 meters away, handheld, 100% cropped. I used the built-in flash and a shutter speed of 1/60 secs at 70mm. The f/2.8 photo was taken twice ... same softness.
The focus is on the end of the letter 'r' of Nikkor on the Nikon box.
