Pretty cool indeed.. and also pretty expensive. That's in the used 5D range..

Sounds like regular EYP (enlarge your penis) device. Let's see actual results!

you'll never be able to overcome physics (no replacement for [strike]displacement[/strike] real estate)
it doesn't make your camera FF, all it does is make the focal length of the lens act as its equivalent FF would (35mm on M4/3 is actually a standard-wide, 50 is standard, etc etc).
also may or may not degrade image quality, although that remains to be seen as nobody has released any sample pictures with it.

... likes film again.
The example shots don`t look to bad .... I just started dreaming about my Summilux 35/1.4 + Metabones adapter + NEX7 ....

When will the X-mount version be available
For Nikon F preferably, and Leica M of course.

My understanding is that the reason this adapter is possible now, is that they have space inside the adapter for focal lenght reducer glass (which is already used for telescopes for quite a a while.) Space that was there converting SLR lenses to mirrorless sensors. Since the Leica M mount is mirrorless as well, I don't think there is space for this glass. A Leica R adapter is already for sale for nex and Fuji X mounts it seems.

This is a pretty big innovation IMO.

THis is the third thread on the metabones. THe main one is here:

And yes, capturing more light on a cropped sensor is consistent with the physics. You are using what would, on a cropped sensor, be an otherwise redundant part of the glass.

Thanks, sorry for double posting this topic, I looked around but couldn't find any thread with it, should have tried the (crappy) search function.
BTW I guess part of the physics is also using that unclaimed space inside the adapter for an extra glass element.

Perhaps this is a repeat thread, but this one is titled appropriately and in the Sony NEX forum, compared to the other.
As an old telescope user, this lens makes a lot of sense -- with an FF lens on a cropped sensor, you end up wasting a full stop's worth of image circle light that slops outside of the sensor area. This lens "concentrates" that light into a smaller image circle. Sort of the same concept as when you use a magnifying glass to light a fire by focusing sunlight into a smaller image circle. Wouldn't work with RF lenses because there isn't enough room for the optics, whereas SLR lenses have to leave room between the focal plane and the mount to accomodate the mirror box.
I've been putting off getting a NEX, but this is moving me a lot closer.

I thought the pdf linked from 43rumors.com is quite interesting: http://www.metabones.com/images/metabones/Speed Booster White Paper.pdf
I'm looking forward to the Olympus OM to m4/3 version.
