Hi
The wife and I are heading overseas shortly, and we would like to upgrade our memory cards but we are not sure about the best ones to buy. We are looking at the Lexar 64GB Professional 1000x UHS-II SDXC Memory Card Class 10, UHS Speed Class 3, or the SanDisk 64GB Extreme Pro UHS-I SDXC U3 Memory Card (Class 10), has anyone had experience with these 2 items, and would like to share their views.

Our Digital camera's we are taking will be the Sony a37, Olympus tough tg2 and a Pentax k x

Kind Regards
David
