R7 RAW burst image resolution

[genevieve]

Have been trying the RAW burst mode on R7. All the images come out at low resolution (1620 x 1080 px). From what I've read they should be at very close to the camera's normal full resolution. As far as I can see there is no way to change the resolution of RAW images, either in burst mode or normal shooting and I can find nothing in the manual.
Am I missing something? Any suggestions how to get full resolution?

Presumably you have the image quality setting at maximum? I would expect the raw burst mode to record at the same settings...
