My first Nikon camera

This is my first Nikon camera, i shoot weddings and portraits with it. The first lens i bought was 28-200mm Tamron, but then I bought a new lens, 24-120mm Nikon. I use Metz flash for my photography work, although I have an SB-26 speedlite, I seldom use it. Its only for my back-up. Speaking of back-up, I bought a back-up camera for my work, and took it as my 2nd camera.
