I have a Nikon D5300, I currently have a Sigma 300mm lens with macro, and the quality on it just doesn't seem the best it is also very annoying when using the autofocus as it is very noisy. I want a better quality 300mm lens for a reasonable price (lower than $500 if possible). I'll be using this lens to take pictures of birds so let me know of other lenses you might recommend for such as well. Thanks!
