manual apreture solution for Blackmagic camera
With the Blackmagic MFT with the following adaptor allowas you to use CANON ef lenses and adjust the apreture manually. It may be the solution to what every one thinks is a huge disatvantage (no apreture controle on the EF lenses)How ever I wonder how solid the adaptor is, any one has any experience with this adaptor???????

The Redrock Micro LiveLens MFT Active Lens Mount is the first active lens adapter allowing Canon EF lenses to be used with any micro four-thirds (MFT) camera, including the Panasonic AG-AF100, Panasonic GH 1/2, and Olympus PEN cameras. A 9V battery and power cable are included.
Canon EF lenses need power and electronic controls to adjust aperture. Without them, aperture is stuck wide open, severely limiting the usefulness of the lens. The Redrock LiveLens MFT presents a solution to the problem, delivering power to the EF lens and a control pad enabling aperture adjustment. Using the LiveLens MFT, you are able to set the EF lens aperture to any stop in increments as small as 1/3 or 1/5, depending upon the lens. The adapter is compatible with virtually every EF lens on the market today, including variable aperture zoom, prime, consumer-level and professional L-series lenses. It also works with the majority of third party EF-compatible lenses.

At this point, there’s only one MFT prototype in the world that I know of, and John Brawley uses it on occasion for testing in Australia for BMD. With that said, John would be the only one to truly know if it would work, and if Redrock Micro sent him one to test one.
I’ve seen this solution in the past, and on paper, it looks like it would work with the BMCC MFT model. No saying for sure until they’re physically put together. I think this could be a great solution, but the original BMCC EF model still has the advantage of Image Stabilization with supported IS lenses. I’ve found the IS feature on the BMCC to be useful and helpful in certain situations.

But but but, I was just getting ready to order the BM (mft), it says its available on their site…..
Id there absolutely no way to get apreture controll on the BMC?
And how does the BMC decide on what apreture to use for the canon ef lenses?

The mtf m4/3 to EF adaptor interfaces between the camera and Canon lens and there is a wired control unit that may be fitted to the pan and tilt handle. Have a look at their website for complete details.
