Thanks Daniel.
300PF+Commlite+Riv does ok, for me. No problem getting focus on the butterflies perched. BIF? I doubt it but no BIF'ing here.
500PF was a no go. Sad performance. It will get there (focus) but might be Christmas.
Same on the a9 post FW 6.0
I did hope for the a9 more than anything. Oh well.
