DJI shows off iPhone-ready Osmo Mobile 2 gimbal with better battery life, easier controls

The accessory's main improvement is a better internal battery, said to offer up to 15 hours of video shooting — more than three times what the original Osmo Mobile allowed. The Mobile 2 is also lighter than before, and equipped with a revised button layout, including a built-in zoom slider.

While iPhone video is normally best shot in landscape mode, the Mobile 2 can also be used to shoot in vertical orientation.

Software-based features include subject tracking, panoramas, timelapses, and "Motionlapses," which are timelapses shot while an iPhone is moving.

The Osmo Mobile 2 will cost $129. After it makes its premiere through Apple, it will go on sale through DJI and various resellers starting in February.
