I've had my H for a couple of months and have done all the updates as required. My videos look great but the stills are soft and smudged on the right side. Being a retired photographer I know this is possibly due to alignment of the lens to the sensor. If I send this in for repair should I install one of the aftermarket lenses and which one. Image quality is my #1 concern. I understand softness in the corners due to angle of view but sharpness is definitely a problem. Any suggestions from someone who has actually had this repair/replacement done ? Thanking you in advance.
