So, anybody else have this problem? It's a D5500 and it has been a workhorse without problems. All of a sudden last week, it started completely unfocusing and refusing to shoot when I aim at a scene that's about 1/3 sky. It doesn't matter how bright or dim the sky is and, in fact, indoors a ceiling will cause the same problem. It shoots completely normally as long as there is not too much sky but if the sky is there, even manual focusing won't stop it from happening.
At this point, I cleaned everything, removed the battery for a while, did a reset-to-default several times and, lacking any other thought, swapped out the flash card for a new one. None of those helped.
I took it to my nearby camera store, a Nikon dealer and dedicated photo store, demonstrated the problem, they tried the same "cures" that I did and they were befuddled. They said that they could send it to the distributor, but that it would cost about $250 even before any parts were replaced.
Has anybody ever had this happen? It appears to be a software problem because everything works unless there's too much sky. If it's going to cost a lot to fix it, I don't know that I want to do that, might just get another camera.
