I recently went full frame (D600) and really like it as well. Only thing I miss, doing mostly wildlife photos, is the reach of the DX. But I am dealing with that. The image quality from my old D300 is amazing. And the more mpx, (from 12 - 24) is wonderful as well. Being able to crop a little bit more helps with the loss of the crop of the DX. I am limited with lenses as my wider angle lenses are all DX. I have not tried shooting in DX mode with it. Kinda defeats the the point. I am hoping to get a 50mm 1.8. I have always loved using the 50mm. So versatile.
I look forward to seeing more of your images.
