I frequently rent the Canon 300 f2.8L and the 500 f4L to use with my 2X II and 1.4X II extenders respectively. I like to use a monopod with the 300 and in low light I often shoot wide open to get the fastest shutter speeds possible. My camera is the 5D MK II. Is it worth it in terms of IQ to replace one or both of my extenders with the newest versions? Maybe a bit faster AF would help too. I am leaning toward buying the 2X III first.
Thanks!
