I never used SD cards, now after getting 750D I will have to use them, however with 24MP an 8GB isn't what you really want.
Any suggestions about SD cards
I want really fast cards 32 GB would be ideal
Sandisk Extreme Pro. No experience with Lexar, Kingston, Samsung or others. Although I don't think one gets really bad stuff as long as I stick to a wellknown brand and don't buy at eBay shops which sometimes offer fake brands.
I've been using for one/two years a 64GB (633x) and a 32GB (400x) Lexar Professional with my Sony a6000 and NEX-6 - many thousands of shots, no problems so far.
