I've found it difficult to buy lenses for my D5200 especially because I want to find an affordable option and there are so many options with lenses to be aware of. First of all, is the lens compatible with the D5200, will it auto focus, does it have a fixed aperture, will it work with the camera in auto mode, does it have VR? There are a number of issues to resolve buying Nikkor lenses, I haven't even tried to figure this out for other lenses, how do I know which Sigma and Tamron lenses will auto focus on the D5200? I bought an older Nikkor 80-200 without auto focus , the aperture is fixed at 4.0 and I can't use the camera in auto mode, which I only do when I'm under the gun and not happy with the look in manual settings, I got a great price by I can barely use it and will probably resell it soon after buying it. I would like an 80-200mm or similar with auto focus with the D5200, even refurbished, at a good price, any suggestions?
