In good light Robin, I liked shooting with the 1d4 with 1.4 TCMK2 and the 400 2.8IS.
That combo for me worked really well. That was for RL. It left a big gap when shooting with the 70-200 on the other body. But it also gave me more time to change over.
I've just sent two bodies for the re-call. I've asked for them back cleaned and modified for Friday, keeping fingers crossed.
