GH4 GH4 Metabones question

I'm looking into getting a Metabones EF Speed Booster adapter for my GH4. I'm having trouble deciding between the .71X and the .64X. Any help would be appreciated.

I want to be able to use EF-S lenses. I know the .64X is designed for FF EF lenses. But can it be used with EF-S lenses physically? And would it counteract the sensor cropping that happens in 4K on the GH4? I'm thinking the .64X might get close in 4K to the native focal length of EF-S lenses.

it will physically/electronically work, but with certain lenses you may see vignetting.
 
If I recall, my cheaper EF-S lenses dont mount right due to plastic thing on the end. I removed it from my 10-22mm, and it works, but the electronics are exposed on the lens now. I know my Canon 55-250mm EF-S does not mount to it. I have the .64 SB and love it.

If I HAVE TO mount EF-s, I use a $14 strait though adapter. Even an adapter I have with a manual Iris doesn't fit the EF-s's

Sorry, I gave bad info, I was thinking about APC EF lenses like the Sigma 18-35.

yeah my EF-"S" doesn't fit. Too deep. Afraid to even try.

Sigma 18-35 and the like work great.
