I’ve not had the D4 long but thought I’d share a few initial thoughts and comparisons between it and the D3s that have stood out for me so far, talking about the ergonomics, a couple of viewfinder changes, a quick high ISO test against the D3s (with RAW file downloads) and more. I'm thoroughly enjoying the latest camera out the Nikon stable, and will be talking about it more in due course as I spend more time using it.
One of the images I've taken of my D4, to illustrate my initial review and D3s comparisons.
The review talks about the ergonomics, controls, speed and various other bits. It also includes a couple of ISO 12800 RAW files for download and look at, as well as a little video giving you a look inside the D4 viewfinder.
