With the vertical Powerboost battery grip VPB-XT2 for two additional batteries, you can literally give the X-T2 a power boost. This allows for up to 30 minutes of 4K video recording (instead of 10 minutes in normal mode) and 11 frames per second in continuous shooting mode instead of 8 frames per second. The electronic viewfinder also operates faster and can display up to 100 frames per second. Additionally, the battery grip is weather-resistant just like the camera itself and provides you with a headphone jack.
