In 2010 Canon released a 120 mp sensor. It’s physical size being 29.2mm x 20.2mm and 13,280 pixels x 9,184 pixels. More Info here: http://www.dpreview.com/news/1008/10082410canon120mpsensor.asp
They didn’t list it’s pixel size, but after doing a little bit of math, I discovered that it’s size is not that much bigger than that of a cell phone camera.
13,280px/13280px = (29.2mm)(1000)/13,280px = 2.1987 micron
9,184px/9,184px = (20.2mm)(1000)/9,184px = 2.199 micron
Your average cell phone sensor pixel size is from 1.4 to 2.3+- microns.
My old Nikon D3s was 8.45 microns. 4256px x 2832px and 36mm x 23.93mm.
If Nikon were to do the same thing as Canon did with the same pixel size Nikon would have a 178mp camera sensor FULL FRAME!!!
(36mm)(1000)/2.199 = 16,371px
(23.93mm)(1000)/2.199 = 10,882px (16,371px)(10,882px)/1,000,000 = 178 mp sensor
If Hasselblad were to do the same thing with the 2.199 micron pixel sensor size…
H4D 60 – (6,708px x 8,956px) 40.2mm x 53.7 mm (factory pixel size 6 microns)
(40.2mm)(1000)/2.199 = 18,281px
(53.7mm)(1000)/2.199 = 24,420.19px
(24,420.19px)(18,281px)/1,000,000 = 446mp sensor!!!!!! And this isn’t the multi-shot either!!!!!!!!
