I brought a new D3300 camera, so I was excited to click a few shots.
As per my expectation, I got few beautiful shots. I encountered a problem when I was shooting under guide mode (adv options) sunset mode. I found that 3-4 times during the 15-20 minutes of clicks, the shutter button got frozen/locked. I was pressing the button, but it was not going through. I turned off the camera and turned it back on, and then it started working fine. I am worried as this incident happened 3-4 times during multiple sunset shots. The camera was fully charged and the SD card is new - Toshiba flash air w-03 16GB. I've never faced this kind of issue with my old D5100.
Please suggest what could be the issue.
