A great short film. I loved the story and the passion that went into making it. Many are going to question the story, but I think the style is more in line with a Terrence Malick film. Telling a story with visuals and keeping interest isn't easy.
Also, using the Beck song "Wave", which is about moving away from disturbance, "only to get carried away" (song lyric) tells you everything about this film. Good film, good choices.
Or buy the Mikaton for $140:
I never had a problem using any CY lenses with the Metabones CY Speedbooster. Which lens are you using?
Why use the EF Speedbooster, since the CY lens has no electronics-on a GH4?
Guy's suggestion to use a CY Metabones Speedbooster makes a lot of sense if you don't want to change the mount. I used to have the adapter when I was using CY lenses on M43. That's the simplest option.
Go with the Leitax. Since it screws into the lens you won't get wiggle that is common with adapters. I used adapters until I read up on Duclos' conversions: he recommends Leitax.
At around 59 Euros, you can't really go wrong. Just make sure you get the right Leitax mount depending on the lens (the website breaks this down).
I have a set of Contax primes that I use on the Red. Beautiful lenses and a great investment! I'll consider getting this zoom lens.
