Thanks for those comments. I am shooting song birds in thick leafed out tree branches right now. I know that is not easy for any lens really but I have everything set to single focus point to try to get on moving birds and avoid leaves. But I am just wondering if something like a D500 or D810...
I have a D3300 that has very little use and just bought a new Nikon 200-500 mm 5.6 e ed Vr lens for it. It is not real quick at auto focus and misses more than I wished. Is this a problem more of an older camera or the lens?
