Looks to be a really great solution that many have been waiting for. If you own Canon (EF/EF-S) lenses you most likely cannot use them on any other camera than a Canon camera. What a shame!
But the Birger lens mount allows you to do what otherwise would be impossible: control your aperture on other camera's. Not only that, it also allows you to focus. And looking at the video, it does a great job of pulling focus.This is not a 15,- eBay adapter and don't bother looking for clones. The basic adapter starts at US $1285,-
How come that everything that Philip Bloom produces looks nice? Even a short test in his kitchen with a nerdy electronic device is pleasant to look at. How does he do that? It's not just his knowledge or expertise, but also the very fact that he shoots these things from his kitchen, the aesthetics of the video, his good looks, pleasant voice and preoccupation with comic and action figures ;-). But enough praise for mr Bloom- take a look at this informative video.
