This is a genuine SONY shooting grip. I purchased it this year and only tried it on my camera once. I have never used it outdoors. It has been stored in the included storage bag. Please note that it has been opened before considering a purchase. ■ Bluetooth-compatible shooting grip with tripod function, enabling high-degree-of-freedom shooting without cables ■ Basic camera operations such as still image/movie shooting and zoom can be performed with one thumb while holding the grip ■ Grip shape provides stable hold even when attaching heavy equipment such as mirrorless single-lens cameras GP-VPT2BT - Brand: SONY - Accessories: Storage bag - Type: Camera accessories Thank you for viewing.
