The wait is over...........it's great and all ...... Didn't they hint at focusing from camera control as well?

Nope. The M43 sensor is larger than the BMPCC's sensor. The smaller the sensor the more light that would be gathered and projected onto that area.

you're obviously correct sir. but for the sake of helping me understand the concept a little better, based on that idea, shouldn't a m43 being smaller than aps c, get a light gain over the speed booster for aps c?

If I were to buy a set of Rokinon T 1.5 lens for a Canon and then bought a Metabones M43/Canon adapter so I could use the Canon Rokinon t 1.5 lens on my Panny AF100a, would there be any drawbacks or a down side to such a scheme? Not knowing any better, it would seem to be good thing, faster F stop, maybe T 1.2 as well as "wider" lens.

It went out of stock in two days. I got lucky and ordered the day it was announced. On the GH4 the Canon 24-105 f4 has a peculiar issue. The F-stop reads f2.8 and goes to F16. Sometimes when I scroll through the f-stop settings the IS jumps. It makes a strange sound too. I hope this doesn't damage the lens. IS does work well.

I really wanted this adapter when I had my AF-100. So needed. A non speed booster model should be available soon. If you got to Metabones you can sign up to be notified when it's available.

Yes. I have taken the lens off several times. I just check it again and it still does it. Only when scrolling really fast.
 
I was thinking... It's to bad the adapter doesn't support EF-S lenses. Using FF lenses on GH4 still leaves a lot of glass unused. In 4K the crop is 1.7. So this is basically APS-C. How can I get a 28 - 85 2.8 with full frame EF lenses when shooting 4K with the speedbooster? I love this range with the Nikon speedbooster and a 17 - 50 lens that we use since day one with the GH4...
