Photographers needing one reliable card

The pair suits photographers who want a spare card in the bag or who shoot separate events and prefer to keep footage isolated. Buyers who need a single higher-capacity card or faster write speeds for burst shooting should look at other options.

Class 10 speed rating

Class 10 guarantees a minimum sequential write performance of 10 MB/s, which is the key figure for deciding whether the card matches your camera’s recording requirements.
