Best camera for the nikon af p 70 300mm f 4 5 5 6e ed vr?
This lens is made for full frame, so I'd start there. The Nikon D750 is my everyday pick: full frame, and it pairs well with a stabilised zoom like this one for walking-around shooting. If you want more resolution for cropping or big prints, the Nikon D850 is the step up.
If you'd rather have reach on a budget, the Nikon D7500 is an APS-C option. On that sensor the lens frames like 105-450mm on full frame, which helps for distant subjects. Just remember the f/4.5-5.6 aperture gets slightly deeper in focus there, so you'll need more light for fast action.
Full details are on the Nikon AF-P 70-300mm f/4.5-5.6E ED VR page.
