Line 91:

In summary, as sensor size reduces, the accompanying lens designs will change, often quite radically, to take advantage of manufacturing techniques made available due to the reduced size. The functionality of such lenses can also take advantage of these, with extreme zoom ranges becoming possible. These lenses are often very large in relation to sensor size, but with a small sensor can be fitted into a compact package.

Small body means small lens and means small sensor, so to keep [[smartphone]]s slim and light, the smartphone manufacturers use a tiny sensor usually less than the 1/2.3" used in most [[bridge camera]]s. At one time only [[Nokia 808 PureView]] used a 1/1.2" sensor, almost three timestwice the size of a 1/2.3" sensor. Bigger sensors have the advantage of better image quality, but with improvements in sensor technology, smaller sensors can achieve the feats of earlier larger sensors. These improvements in sensor technology allow smartphone manufacturers to use image sensors as small as 1/4" without sacrificing too much image quality compared to budget point & shoot cameras.<ref>{{cite web |url=http://www.gizmag.com/camera-sensor-size-guide/26684/ |title=Camera sensor size: Why does it matter and exactly how big are they? |author=Simon Crisp |date=21 March 2013 |access-date=January 29, 2014}}</ref>
