As a photographer, please enlighten us as to whether or not an extra few millimeters is actually enough to "significantly improve" the iPhone's camera. I am merely an amateur photographer so I'm not certain, but it seems to me like if Apple want a "significant" improvement in camera capability on the iPhone, they'd need to do much more than add OIS and a few extra millimeters.
Thoughts?
That would depend on the lens, apple's price they are paying the manufacturer, etc. I don't know who makes their lens, but probably this is the size and price that fit their spec's.
I'm a retired amateur photographer. I shot quinceaneras, weddings, baptism's, etc.
