ef will fit most ef-s (crop sensor) canon cameras, just not the other way around, check your mount, you should have two different alignment dots. white dot is for ef-s, red dot is for ef.
it will be the same, it will accept ef-s or ef mount lenses, so you will be good to go, thats a great deal on the camera, and if you dont buy it i might, i already have a full frame 6d, but a crop sensor like this would be a great backup..
