Just saw this today on their website, surprised more people are excited by this.
While I think AJA & Black Magic mini-converters are really great, they come out of the box ready for shore power. If you need to run one off a battery it takes some extra money & you have to look around to find something that works. According to Atomos the built in battery will last 2 hours & automatically switch to the internal power if an external batter or AC power dies. Plus the smallest L-series battery is listed to last for 12 hours.
As long as these Atomos offer the same quality in conversion (vs AJA, Black Magic)... these will be amazing.
PS I'm personally thinking this could be a great easy add on for a Sound Devices Pix 220.
