I was just looking into getting a metabones EF to MFT adapter (NOT the speedbooster which I already have) when I came across this product
I did a quick search but couldn't find any discussion of it here on the forum. Anyone out there using it? Thoughts? Here's a review that I found on youtube
Given the fact that the price is less than the MB adapter I wouldn't even mind so much if the focus side of things was a bit flakey as one of the reviews on BH seems to suggest. It still allows aperture control. The only very minor downside that I can see is that you won't get a read out of the aperture on your screen or monitor from the camera because the adapter isn't communicating with the camera its just communicating directly with the lens. This is probably one of the reasons why it is cheaper than the MB adapter- no need to translate between EF and MFT protocols.
They also now do a speedbooster version.
