Canon rf100-500 vs ef 100-400 mkii
I'm really just trying to decide if I should save the extra $1000 and pick up the ef version. I shoot on a canon R7 and R6mkii and I'd be using it for wildlife. I'm just wondering if that extra $1000 for a little bit of sharpness and newer autofocus is actually worth it or should I just pick up the older model. Right now I'm using the Canon ef 400mm f5.6 so I'm looking for something a little newer seeing how that lens is pushing 30 years if not already lol.
Also I'm open to some primes that are in the same price range if yall know some.
