Metabones speed booster + focus peaking

If Fuji finds some way of adding peaking to the X-Pro1 I would definitely purchase one of these adapters. There are quite a few good old lenses that would become super lenses for portraiture. The problem I have with the current manual focusing situation is relying on the EVF (and my judgement).

This product does seem too good to be true. But its legit!
