Hi, been considering these two lenses for my setup for quite a while, gimme so much headache...
(a) My camera is a D5100, meaning it doesn't have a in-built focus motor. So, the 80-200mm is now a manual focus lens while the 300mm f4 is an autofocus lens. Does autofocus matter that much?
(b) Aperture size. f2.8 vs f4, which is better for birding, wildlife etc? How much in difference of performance?
(c) Zoom distortion affects image quality much?
(d) Overall which is better with my current camera body?
Thanks in advance for replies!
