Lexar Professional 2000x SDHC/SDXC UHS-II cards let you quickly capture and transfer high-quality photos and extended lengths of Full-HD and cinema-quality 4K video, with a read transfer speed up to 300MB/s (2000x). The cards also leverage UHS-II technology (UHS Speed Class 3 (U3)) for high-speed performance, so you'll power through post-production with super-fast file transfer from card to computer. This dramatically accelerates workflow from start to finish, so you can save time and get back to the business of photography. These cards also come with a limited lifetime product support.
