I'm having problems with my Nikon D5100, generally when I first pick it up it will work fine for 3, maybe 4, shots then the button just stops working, I press it but nothing happens. If I change to the screen view mode (instead of looking through the view finder) it generally works again but is very slow to respond. Any ideas? Note: It doesn't always work at first sometimes it's not working from the off.

    \$\begingroup\$ The fact that it works with live view mode suggests to me that it's a focus issue. That's because the two modes use an entirely different technology for focusing. You don't happen to be running into this problem, do you? \$\endgroup\$

Try switching to manual focus mode (MF switch on your lens). If the problem solved - your camera has troubles focusing. The reasons might be:

  • Insufficient light
  • Lens AF problem (try a different lens to see if the problem remains)
  • Body AF problem (contact service)

If MF didn't solve the problem: Try a different memory card. After you snap a batch of photos, they are queued to be stored to a memory card. This takes time. Cheaper cards are slower. Plus, the queue isn't infinite - depending on your camera, it can hold no more than, let's say, five shots.

  • \$\begingroup\$ Memory card could also be close to failing. \$\endgroup\$ Feb 24, 2016 at 14:23
