Sigma is offering a service to change the mount. This could be the way to go, because it's an excellent lens and better than any 24-70 in my eyes, even if I'd have to crop some shots. At least the Nikkor 24-70 is not that good at the long end, so I dare say for my way to take pics and also get a bit closer to the subject by foot instead by zoomring the Sigma is due to it's speed superior.
Okay, there's a lot wide angle not covered by the Sigma and it's not always possible to stitch two shots. Your decision. I wouldn't buy a used D600, this can be a surprise package. And that wasn't meant pleasant. Also, I can't say anything about the Canon, never shot with it, but the D600 has a limited AF. If you always focus close to the center of the picture, no problem. But the more you like to come to the border of the frame, the more you'd miss more AF points.
