Three months after I purchased my D5200, I gave up trying to get tack sharp pictures. I tried all settings ISO100, f8-16, 1/200-500 and still I get soft pictures. At first I thought it was the lens but the same problem occurred using faster and better lens. I brought my camera to the service center and they told me it has problem on back focus. I thought D5200 never has internal focusing system. But since they said it has problems, I am counting on them to fix it. Too bad though, I bought the camera for a family occasion and all I get are sub standard pictures.
