I thought my D810 was insane at 36MP, but that's just unbelievable.
It almost enough to make me consider the switch!*
*Almost.
Dont you worry the D820 is already being worked on and I am pretty sure it will have an even more insane sensor on it with probably 60MP or 70MP on it.
Ladies and Gentleman this is the Japanese muscle car style war of sensors, the moto is "Let See How Many MP We Can Cramp Onto One Silly Sensor", I bet in few years 100MP sensors will look rather normal.
I am not saying this is pointless for everybody, yes there will be those who will really make good use of this large resolution but come one even 36MP is stupidly huge resolution and poitless for most of us.
I know that MP at these levels is pointless for the vast majority of photographers, amateur or professional, and it was something I never really cared about until I started working in the studio, where clarity and detail became important to me in my photos.
I'm certainly not saying a 50-60MP is better, let alone necessary (far from it), but for my own photography - resolution has gradually become more of a consideration for future potential camera body upgrades.
Plus, I also find it a little bit fascinating, shooting a portrait from 3-4 metres away and still being able to zoom in and see the eyelash follicles!
