I don't like to look a gift horse in the mouth, but the D4s body that NPS loaned me had the dirtiest sensor I've ever seen...and I didn't know it until I got home and started looking at the images from Yeovilton and Duxford. Here's a shot of the B-17G, and the corresponding spot-removal screen from Lightroom.
Except for all the work the dirty sensor has caused me, I really enjoyed shooting the D4s: responsive, awesome burst mode buffering, fast-focusing, good ergonomics, and great battery life (I shot 160 GB of RAW images on one charge, with plenty left in the tank).
