IRL: IOGEAR GearPower GMP10K, SteelSeries Free Mobile Gaming Controller and the Metabones Speed Booster

Welcome to IRL, an ongoing feature where we talk about the gadgets, apps and toys we're using in real life and take a second look at products that already got the formal review treatment.

Anyone out there a fan of Sony's mirrorless cameras? How about Canon's premium glass? Good. We knew there'd be some of you. In any case, with this week's IRL, we'll be sharing everything you ever wanted to know about the Metabones Speed Booster, which fastens your full-frame EF lenses onto Sony's E-mount NEX cameras. And, of course, what would an IRL column be without an external battery pack? (Seriously, we can't live without 'em.)
