Just a quick one. If you find your camera isn't performing as expected check the class of memory card you are using! I had an 8 GB Class 2 card from my old phone, and video was jumpy and delay when pressing the onscreen 'shutter'. Bought a Class 10 card and it's fine! I didn't even know class existed until I stumbled across this whilst looking for a larger card.
