Wildstraw, I believe the CF will be prefered in your camera. If you even put an SD card in along with the CF to make backup images at the same time or something, it will reduce your FPS. Using a high quality high capacity SD to mirror your CF for wedding shoot = intelligent. It will in fact slow down the FPS if shooting sports though.

I don't shoot like that, so I occasionally put a microSD into an SD adapter, put it in the camera and write low res Jpeg and write full size raw to the CF. I can pull the microSD and pop it into my Galaxy Note II and dropbox the images immediately, or do twitterbookspace, etc. So you would be taking images before post and uploading them immediately. This, so you can keep up with the instaphones and tweetpages of the era, but with 1D quality images from a pro photographer.

If enough people do this, besides always looking busy fumbling with a microSD card in between shooting, we'll outdo those iphone and point and shoot jockeys and show them how its really done. On that topic, the panorammic apps are really downplaying a lot of my work and they are nowhere near the quality of my 65,000 pixel width high res (cant even be created in jpeg due to size) panoramics. /endrant

Android was originally developed for point and shoot cameras, not for mobile phones, fyi. I'm researching a way to use wifi enabled SD cards along with my Androids wifi capabilities and 4G to do streaming to remote server of a photoshoot, not with the Canon attachment though.
