Nice demonstration, although a dp2 Quattro would look better in the same light at f/2.8, 1/60 sec and ISO 400

The fp high ISO is amazing, 102,400 is quite usable in monochrome, although the in-camera JPEGs get a bit soft at that point.

This is not intended as a rebuttal, Johan.

I just don't understand the apparent fetish for seriously under-exposing a sensor and getting away with it.

Acceptable results in available light are a big step forward. I've lost so many shots because there wasn't enough light. You press the button anyway, hoping to get something, and the result is vanishingly thin negatives or hopelessly dark digital images, even at dangerously slow shutter speeds.

May I ask what the "native ISO" is for an fp, assuming the SOS method?

There are two "base ISO" numbers, depending on which of the analog amp gains is in use.
