The best lens to use with GH4?
I have GH4 and I'm planning on getting the Metabones Speedbooster EF to M43. I can't really decide which lens to get with it. Since I can afford only one lens at the moment, I want the best option out there for less than 1000$. I have my eye on the Sigma 18-35 f 1.8 zoom lens but it does not have OS. I'm searching for a zoom lens that is very sharp and has Image Stabilization.
Sigma 24-105 comes with OS and is sharp but not very fast at f4.0 and 24mm on GH4 might not be wide enough for filming even with the speedbooster.
Mainly I'm looking for a lens to use for both stills and video preferably with constant aperture .
Btw, does the speedbooster enables autofocusing?
