Leaf just unveiled its 80MP Leaf Aptus-II 12 and Aptus-II 12/R.
That's an 10,320x7,752 pixel image from the 53.7x40.3mm sensor.
My H3DII-31 has a 44x33mm sensor. While there seems to be a standard with 35mm dSLR when they say "full-frame", the MF dSLRs keep pushing the limits to what they consider "full-frame". Sensors keep getting bigger.
Sounds like Canon vs. Nikon all over again. Your move Hasselblad!
