Af/ae lock

Does the lumia 920 have this feature? Ex. From iPhone if you press the screen for a few seconds it locks the exposure which is pretty handy as you get the preview of exposure and shoot at anytime.

what ive been doing is half holding down the shutter button(camera button) then composing my shot then fully pressing down to take the shot. hope that made sense.
