How about 4 or even 5
Lens that is
Reminds me of watching all the 1960's footage of the space program this summer where the old TV cameras had a turret of lens on the front. Then people cracked acceptable zoom lens and the turrets went the way of the dinosaurs. I guess that including different camera for wide, standard & tele just means they haven't found out a way to make a zoom lens flat enough to fit in the phone yet.
