How many of you customize you camera controls? For instance. I have my FN button set up to initiate the virtual horizon. Often times when I take a shot i'm kneeling down and looking through the view finder sorta sideways resulting in a shot not level. The virtual horizon solves this. I also have my playback set up to automaticly zoom in on the focus point to check sharpness without having to zoom zoom zoom pan pan pan. Of course the more advanced the camera the more customization controll you have. So check out this site.Top Ten Nikon Customizations You Must Know!
