Isn&#x27;t it exactly the opposite? The smaller the area, the less photons land on it in the given time, so the sensors with the bigger pixels can capture more light, and the less nm features measure the more of noise and less of signal.<p>That&#x27;s why if you want good pictures in low light you need a camera with as big sensor as you can get.<p><a href="http:&#x2F;&#x2F;www.dpreview.com&#x2F;articles&#x2F;5496399487&#x2F;canon-multi-purpose-me20f-sh-camera-reaches-iso-4-million" rel="nofollow">http:&#x2F;&#x2F;www.dpreview.com&#x2F;articles&#x2F;5496399487&#x2F;canon-multi-purp...</a><p>&quot;At the core of the ME20F-SH is a 2.26 megapixel CMOS sensor, originally announced in 2013, which has pixels measuring 19μm - 5.5X larger than what&#x27;s found on high-end DSLRs. This allows for 1080&#x2F;60p&#x2F;30p&#x2F;24p (and PAL equivalent) video capture in light levels as low as 0.0005 lux at a maximum gain setting of 75 Db, which is equivalent to over ISO 4,000,000.&quot;<p>Note: the pixel is <i>larger</i> and therefore the sensor more sensitive. Canon made the <i>full frame</i> sensor with only 2 megapixels and obtained the higher sensitivity.<p>Comparing with the cameras in phones, the area of the whole sensor in iPhone 6 is 50 times smaller than the area of the full frame sensor.
