AF/AE lock

[mohammad-sajjad11]

While in a moving car or walking you try to focus on things or object by touching and then it auto adjusts the exposure and focus. While in a moving car there is an object in front of you and then you touch on it and ut adjusts accordingly but since the car is moving and your hands are moving too no matter how hard you try so a bit of moving immediately changes the focus and exposure as soon as it feels the object as something else where as I want to snap the object in front.

So for that A button for AF/AE lock would be awesome. You touch, it adjusts and then lock. So you can easily take the pic of the object you want to...
