Is the D7200 camera and Nikon 70-300mm af-svr Full Frame Lens compatable

SOURCE: repairing 20mm af nikon lens diaphragm lock

I'll offer the same answer I just gave on a D200 question: With the lens off, look at the camera mount area. If you are looking straight at the mount, there is a small tab sticking out at about 7oclock on the outside edge of the mount ring. The tab is spring loaded and may be damaged. You should be able to push the tab toward the base of the camera and it will snap back if functioning properly. If it feels loose or doesn't spring back, then switch that ab controls is not being activated.

Is the switch on the side of the lens set to manual or auto? Sometimes it's the little things like this that we don't notice.

Hi,
Sorry to hear about your lens. If you are able to autofocus and take pictures with any other lens, then it means that your problem lies with the kit lens. If you can take picture in manual mode, but not in autofocus mode, then the AF motor in the lens in not functioning. I had the same thing happen to my 50mm 1.4 lens.
Depending on your location, there are Nikon repair centers in Melville, NY and Torrance, CA.
Hope this helps,
Andrew

SOURCE: I have a Nikon D3100

That lens will work with the D3100, except for the autofocusing. In order to autofocus with the D3100, you need AF-S lenses, such as the AF-S VR Zoom-NIKKOR 70-300mm f/4.5-5.6G IF-ED or the
AF-S DX NIKKOR 55-300mm f/4.5-5.6G ED VR.
