Is the nikon af s 70 200mm f 2 8g ed vr ii good on aps c?
Yes, I think it's a good fit on APS-C. On a Nikon APS-C body it frames like 105-300mm on full frame, which suits sideline sport and close-in wildlife. The f/2.8 aperture gives about the depth of field of f/4.2, still handy for lifting a subject off a busy background.
I'd pair it with the Nikon D500 for fast action. The Nikon D7500 and Nikon D7200 are lighter alternatives that still do the job well. If you mostly shoot birds, read the wildlife and sport reach guide first, because you'll probably want more focal length than this lens gives you.
