What is the difference between a SD card and compact flash card I use in my 7d. I want to get a full fram camera but 6d takes only SD cards. Is there a big difference?

Re: 6d

SD cards are cheaper.


Both will record your images in the same, exact way.

They're just physically different. Like David said, SD card is much cheaper, a 64 GB card can have for about $55 from reputable sellers.

Re: 6d

I have a 7D and a 6D.  You're right, the 7D uses CF cards and the 6D uses SD cards.  For each camera, I have a 128GB card and I've never been able to fill either up at any event I've video'd or photo'd. 


Make sure you get a fast card, whatever you choose.  There are different write-speed ratings for both CF and SD cards.
