I'm a little bit confused. What is the size of a 1/2.5" image sensor? Do I take 1 divide by 2.5 to find the size in square inches?
And cameras such as the Panasonic FZ series have apertures of f2.8 throughout the zoom range, but why is it that the camera is still able to take landscape or pictures requiring large DOF yet still clear with just f2.8?
