Hey guys, I picked up the new Nikon D810 the other day for my headshot/portrait work and I wanted to share some images and 100% crops from both cameras..
What you'll see in this example is how much more resolution you get to play with in the new Nikon D810.
The Nikon D3s is a 12mp full frame camera originally designed for low light high ISO shooting for things such as sports with its 9fps high speed shooting and shooting incredibly dark available light settings like you would find in a dimly lit church at a wedding being able to shoot comfortably up to 12,800 ISO.
On the other hand, enter the new Nikon D810, a 36mp behemoth that has so much resolution and sharpness that it will cut off your fingers if you're not careful. This camera has been improved from the D800 and D800E to increase the high speed frame rate to a base of 5fps and 7fps with the additional Nikon MD-D12 Battery Grip. The D810 now also has an ISO range from 64 ISO to 12,800 ISO making it a big step up for a camera with this sort of resolution.
