Micro SD v SD cards...any difference?

Hi,

Can anyone tell me if theres a difference between using a Micro SD card with adaptor (so it fits in a regulard SD card slot), over using a regular size SD card.

I’ll be using it in a dSLR camera and possibly shooting 4k video; I have the Extreme Pro 64Gb UHS-1 micro SD cards.

Thanks for any feedback!

Alan.
