Buffer of my Canon 7DMK2 with photo quality set to RAW (Large) shows 20 photos. A few days back it dropped to 16. I checked the different settings and could not tell any difference.
Reformatted both cards, switched between both cards and nothing happened, the buffer remained at 16. Finally after checking with another user to confirm that the normal rate was 20, I reboot the camera, clear all settings back to factory, remove batteries etc. and after getting everything back to my normal settings the rate is back to 20.
Not sure what caused the drop or what fixed it. Have anyone seen this?
