Hi /p/, sc/out/ here. I don’t know anything about cameras and I recieved a used Nikon D80 for my birthday. The lens it came with is for taking portraits. I’d like to get a lens for it that I can take pictures of sailboats and birds from far away and it will autofocus for me because I’m retarded when it comes to cameras. Any suggestions would be apreceated. I also asume I’ll be looking for used ones to keep it affordable.
