There is
probably a slight delay, but it's so small that it's imperceptible — judging from a non-scientific test, it's less than 0.1 seconds and shorter than the lag on the HTC One X. Overall, the speed and ease - of - use of this camera can change the way you shoot pictures — not simply by filling up your microSD
card with more
photos than usual, but by encouraging you to push for ever more interesting shots that wouldn't possible on a regular laggy phone.
