What is the recommended storage size for the memory card?
We recommend using Class 10 or above memory card that is bigger than 16gb in capacity (For 4K video shooting, we recommend using memory cards with >80mb/s write speed). While shooting with JPG-L format and 20-megapixel resolution, each photo will take up Approx. 8mb, which means that a 16gb memory card will be able to hold about 1000 photos. While shooting 4K video, a 4-minute video file will take up Approx. 4gb. Once the limit is reached, video recording will stop automatically (Length limit about 7 minutes and 29 seconds). Therefore we recommend using a memory card with larger storage size for better flexibility.
