On: The demise of the DSLR

[cespare]

I was under the impression that going for a massive megapixel count like 40 on a tiny sensor like most smartphones have (iPhone 5's is about 4.5mm x 3.4mm -- miniscule) is entirely pointless because the pixels start getting much smaller than the airy disk[1].

Interesting..

"This gives a value for x of about 4 µm. In a digital camera, making the pixels of the image sensor smaller than this would not actually increase image resolution."

So, the HTC One, which only has a 4 megapixels is already at that limit: http://www.htc.com/www/zoe/ultrapixel-sensor-size/

(and if the marketing graph below is true, the Nokia sensors are half as big..)
