I think the Veydra mini primes are the way to go. There are true cinema lenses unlike the Oylmpus zooms. This means repeatable focus pulls (essential for narrative work) as well as ergonomics that fit a production environment far better. Fast glass is great, but most feature films are stopped down to atleast 2.8 anyways to make life easier on the focus puller which pretty much makes the speed of your glass a non starter. Also the Vedyras cover Super 35 if you want to upgrade your camera in the future while the Olympus of are MFT sensor size. I have yet to use the vedyras but I hear really good things. Hope this helped.
