As I've mentioned I own a full spectrum converted infrared camera so it 'sees' most of the ultraviolet and infrared range of light (deliberately blocked in a normal camera) as well as the visible spectrum. You can limit this to parts of the visible + infrared spectrum by using external filters. I have four filters that cut off wavelengths below 590, 630, 720 and 850nm respectively.
The images show the RAW output from the camera (converted to unprocessed jpg for forum display) with no filter and each of them in turn.

Interesting the amount of color delivered by the 850. On my Fujis, the 850 produces what amounts to a black-and-white image, right OOC.

Also -- do you do anything in UV?

This is the first shot with the 850 and I was expecting essentially b&w too. It is a cheap no-name filter but will try it on my X100T and see.

Here is the RAW (as jpg).

Here it is processed in ACR as others were.

And for comparison here is yesterday's image from the Pana GF1. It seems this sensor is seeing more red(swapped to blue).
