FS7, FS700, Speedbooster EF to Emount, Autofocus solution needed, Thanx!

Hallo,

I just figured, that Auto Focus might not work well for adapted EF lenses on the FS7 and FS700. Only on A7RII with its Phase detection.

Would that be the same for the non speedbooster version?

Wouldnt make sense then to work with EF lenses on the two cameras, if auto focus is wanted for documentary filming?

So are there good autofocus solutions for FS7/700 other than native lenses?

Wouldnt make sense then to buy the Canon L 24 105 F4 for autofocus purposes?

Why not buy the sony 18-105 f4?

The AF is only barely good on E-mount glass. You need the 18-105mm kit lens for documentary stuff for AF with FS100/700. It works great for grabbing focus before recording and has a perfect documentary range.

With Canon glass and Metabones, no way, you'll wait 5 seconds watching it hunt and pray it locks on in the end. Only newest A7RII & A6300 will work OK with Canon glass. 

I did hear of a company that makes EF-E mount adapter with really fast and good AF on these older cameras, http://www.kipon.com/en/articledetail.asp?id=79

Not out yet but when it is (soon) it's worth a try if you own EF glass & FS700 & NEED AF.

Thanks guys, the 18-105 seems very nice for run and gun documentary work.

Thank you once more for putting light into the darkness of assumptions:)
