DX mode - Do You Use It?

I love my Nikon 17-55mm 2.8 lens and really in the 25+ years I've been a photographer,it's in my top 3 lenses. I will not give it up. Sharpest,perfect lens!

So,now that I have the D600 I am using the DX crop and my shots still come out great.

When I had the D700 I didn't have this lens and with the crop,my images would have been too small for client work or stock photos.
