Hi, I have a 800mm f6.3 and a 600 f6.3 but at times I feel the need of more light. The Z 600mm f4 is out of range for me considering also the lenses i already have. I am considering the AF-S 600 f4E with an adaptor for my Z8. Does anybody have tried this combination and in particular, how is the autofocus and resolution?
