How does the D3 achieve such high ISO?

Re: what are you smoking?

Essentially, the reasons why Nikon does well in high ISO right now:

-12MP on a full frame sensor - very low pixel density. This is probably the main reason behind noise, and with the 1D3 being 16.x MP in a full frame equivalent, it's clear to see their pixels are a fair bit larger.

-ISO200 base. I don't know how much this helps, but you'd think it gives them close to a stop more headroom at the top end.

-extra NR done in camera, even when the option is disabled. This has been well documented.
