Earlier this year, I started to get fuzzy pictures with my X-T2 (and the 18-135mm lens) so I sent them in to Fujifilm to check. Back they came with the report that they were "both performing to specification." But at the foot, under "Remarks", there was this: "Please be aware that using on fully Auto Mode, shutter speed and ISO, can affect that camera [which] has its issues with focusing." Not very well expressed (so I added the "which") -- but most worrying. That was a month ago. Since then I've been testing it with either the ISO or the shutter speed (or both) on A[uto]: at relatively close range (3 to 10m): never a problem, sharp as a pin; 10 to 30m or so: OK depending on what I've focused on. BUT at a greater distance (e.g. landscape, which is what I photograph most), 1 photo out of 3 is unsharp or frankly blurred. It's not a problem of camera shake. It happens with speeds up to 1/1000, and at ISO 200 to 400.
Has anyone else had this?
