that is just maddeningly unhelpful.
I have had a similar issue with my FA77 some time ago, something got caught in the gears that turn the focusing ring and prevented it for focusing at longer distances, I repaired it myself*. Since your lens is a DA series lens with quick shift I surmise the same thing has happened to the AF gears but thankfully it hasn't affected the gearing for the quick shift feature - so you can still manually focus. I recommend you get your lens looked at by a qualified repairer.
* It goes without saying that I don't recommend repairing lenses on one's own,
unless you
really know what you are doing.
