Metabones, not long ago, announced a new Speedbooster purely for the BMPCC camera, which provides an even greater focal length reduction than regular adapters: http://www.metabones.com/products/details/MB_SPNFG-BMPCC-BM1. Looking at the adapter, it appears to be very similar in depth (between the two mounting surfaces) to that of the MMF2 and MMF3. I've been very interested in the BMPCC since it came out, especially since it has an active m4/3 mount, which means my existing lenses would work with the camera. However, even though it has a m4/3 mount, using 4/3 lenses with an adapter, still means that all the effective FLs are multiplied 3x. This is kind of disappointing, as so much is lost even with a 7-14mm. So I've written to Metabones enquiring whether there is a possibility of them creating a similar (active) adapter with a 4/3 mount, given that the dimensions (looking at the photos only) appear to be very similar to the MMF2/MMF3. I understand that they would need to get approval for the active connections, but considering that Blackmagic has been able to do this (and they aren't a major company), I can't imagine it would be impossible for Metabones to do the same. I'm not holding my breath, but it would provide new opportunities to a lot 4/3 lens owners and possibly boost the popularity of the BMPCC even more. Though the adverse affect might be escalating used prices for 4/3 lenses.
