This issue started today all of a sudden - there is really bad stutter when panning in the viewfinder and slightly less in live view. I recorded a short clip and played it back on my PC - there is indeed severe stuttering when panning. I am recording in 25p FHD ALL I, shutter 1/50. I have a wedding shoot next week and I am panicking - any advice on what might be the cause?
p.s initially there was stutter in the viewfinder in photo mode too but this has been eradicated after clearing and resetting the camera settings.
