Another thing I like that Nikon is adding to its cameras is a 1.2x crop mode. On the 24.3MP D750 sensor this delivers a 16.7MP image in a perfect 3:2 35mm format. The final image size is almost the 50MB required for traditional stock photography. So, if the image isn't cropped, there is no loss in resolution. I find myself bouncing in and out of the 1.2x crop mode for two reasons. First, the smaller crop means that the 51 focus points cover a much larger percentage of the image area. Second, my 85mm f/1.4 is immediately converted into a 102mm f/1.4 lens, and the 50mm becomes a 60mm f/1.4.
My main studio is set up for daylight shooting, and on some stormy days it can get quite dark. I need to keep my shutter speed high to stop the action of the moving models. On my last shoot I was using an 800 ISO for most of the day. For the D750 the noise level on anything up to around ISO 1600 isn't even noticeable.
The auto-focus ability of the D750 includes all the improvements in the D810 and D4s and then some. In 5-point group mode or 3-D auto focus the camera is as good as it gets, even in the dimmest light -- or should I say "especially in the dimmest light".
