I love my Sony z5 but camera is a real let down. Is there anything I can do to make the camera work faster? The focus is slow and it takes 1 to 2 sec to take the picture and save it. Also the quality is not impressive at all. I feel iPhone6 takes a lot better and faster pictures. I have read few blogs where they praise Z5 camera, am I missing something? I really don't want to give up my Sony, but I may have to because of the camera. Please help...
