Having the same issue using a Cannon KT14x4.4KRSJ. Took the lens to Cannon to check back-focus, they said it’s performing within specs. All looks fine in camera viewfinder but when I get back to base it’s soft/hazy. I can’t find anything on this, very frustrating. I just changed the record format to H.264 1920×1080 30p (XHQ) need to test to see if it helps.
