If I only had $1300 to spend on lenses for a MFT camera that would be used for music videos and short fillms I would purchase a Metabones Speedbooster Ultra (Trending @ $350 on ebay.com), Sigma 18-35 f1.8 (Trending @ $650 on ebay.com) and a regular EF to MFT adapter (Trending @ $100 on ebay.com).

Using the Speedbooster, the Sigma 18-35mm f1.8 becomes a 12.8-25mm f/1.2 (S35) effective lens, which is faster than most primes (expect the Voigtlanders and maybe Veydras) available for MFT, with the convenience of a zoom lens.

I'd be looking to use the crop factor of the MFT camera to my advantage to get "two lenses for one". Once you swap out the adapter the Sigma 18-35mm f1.8 becomes a 36mm-70mm f/3.6 (S35) effective lens. Although the Sigma is "f/1.8" it will have the equivalent depth of field to an "f/3.6" lens. This means the amount of light the Sigma 18-35 lets in will not change, only the depth of field or the "blurry part" of the image.

This setup gives you a decent range from a S35 equivalent of 12.8mm - 70mm with about $200 left over. I'd use that $200 get a cheap Variable ND filter ($50), Circular Polarizer ($50), and a Black Pro Mist filter ($100) off ebay.

Well done guys!! Very good interview :)

You hit the nail on the head. Does anyone make a wireless transmitter that uses a smartphone as a receiver? I'd think this could be accomplished via bluetooth. I could be wrong though ¯\_(ツ)_/¯, either way, this seems like it's just a tangled mess waiting to happen.

I still own and use quite a few tungsten units. Primarily for corporate video gigs where a green screen will be used. They aren't a "bad idea" to get if you can guarantee you'll have wall power, space (heat). and time. The Arri knockoffs on eBay aren't as horrible as you might think, but they are cheaply made and won't really hold up over time.
Some other brands you might want to consider searching for on eBay or keh.com:
Arri
Dedolight
LTM
Mole Richardson
LowelPro
Smith & Victor
Bardwell McAllister

Maybe I'm just getting too old to be excited about these types of things anymore. This phone and it's face recognition is a hard "Nope." for me.
