I Currently have a D7500 and a 70-200 F4 lens. I am going to start shooting more sports and wildlife and wondering which lens would be better. I am considering and 80-400 or a 200-500, or possibly just a telecoverter for my 70-200. I have heard the 200-500 is a very large and heavy lens. Is the 80-400 nearly as big and heavy? Picture quality is a concern as I will be making some large prints of some of the photos and fast AF is also a concern as I will be shooting action shots. I am fairly new to digital photography and have never used a teleconverter, so not sure how they work. What do you guys think would be best for me?
