    I’m torn between the Lexar Professional 2000x and the Sony SF-G Tough. I do a lot of outdoor shoots and the ruggedness of the Sony appeals to me. But is the Lexar really much faster?

    • I have the Lexar and it’s super fast, but I haven’t tested the Sony. If you need durability for outdoor shoots, the Sony might be worth it.
