With a fast card, continuous recording capacity of your camera is not clamped and it can therefore capture images as quickly as possible.
The capacity of 32GB enough for me, I am even more fervent of 16 GB, but the price made me decide.
This type of card class 10 is recommended for HD and Full HD video recording to maintain a good flow of writing well and enjoy all the capabilities of your device (camcorder or camera or mobile camera apparatus ...).
Recommend with confidence!
