I've had the opportunity to get out and shoot with my new D800 over the last couple days. Also had time to review the manual as there are some differences between Nikon's system and the Canon system I've shot over the last 7 years.
The manual shows that the camera is campable of 3 NEF FX sizes: L (7360*4912), M (5520*3680) and S (3680*2456). While the times would likely be few and far between, I like knowing I have the option to capture a smaller size NEF file. However, for the life of me, I can't figure out how to change the size from L to M.
What am I missing or am I interpreting something wrong?
