Is the nikon af s vr 70 300mm f 4 5 5 6g if ed worth buying used?
Yes, I'd happily buy this one used. Lenses hold their value far better than bodies, so a second-hand copy of the Nikon AF-S VR 70-300mm f/4.5-5.6G IF-ED is a sensible way to get a long reach without paying full price. It's stabilised and autofocuses, and it fits Nikon F bodies. On full frame, like the Nikon D750, it frames as marked. On APS-C, like the Nikon D7500, it frames like roughly 105-450mm.
If you buy a used body alongside it, budget for a new genuine battery, since old ones lose capacity. The buying used guide covers the rest. If you're chasing animals or action, wildlife and sport is where this range earns its keep.
