Anyone using the Metabones rf-ef speedbooster?

I'm considering buying into the Canon mirrorless system, as I will soon graduate from journalism school and will no longer have access to my school's 5Ds. Right now, I'm debating between an R5 and a rigged up EOS R. I figure the R5 will be at least $4k USD, and for about the same money I could get:

  • Refurbished/Used EOS R ($1500)
  • Metabones RF-EF Speedbooster ($480)
  • Used Tamron 85 1.8 VC ($485)
  • Used Canon 24-105 f4 IS ($400)
  • Used Ninja V ($625)
  • 1TB SSD ($115)
  • Smallrig Cage ($100)
  • Rode Videomic NTG ($250)

My only concern is with the speedbooster-- Can anyone comment on how good the video autofocus is using it?
