Smartphone camera sensor sizes visualised, light gathering ability calculated
It's a fair cop, I'm firmly in camera geek territory again here. We see a lot of smartphone camera comparisons online (not least here on the All About sites), but all this talk of optical formats and pixel sizes rather gets in the way of the man in the street understanding the simple physics involved. To help out, I've summarised all available data on smartphone camera sizes and apertures and present the result graphically. So the Lumia 1020 has a 1/1.5" sensor - what does this mean? And how does it affect the ability of the device to gather light? This and much more below...
