Now that I have the Nano Flash I am looking for a camera that is basically only a 'head'. Would something like this: Gigabit Ethernet CMOS Cameras: SMX-12A2C (http://www.sumix.com/products/cameras/smx-12a2c.html) be suitable to build a really small and extremely good camera?
Does anybody know of other camera heads that could be combined with the Nano Flash? I know that SI2K makes this tiny camera to be used with their recorder.

The SI 2K is problematic, as many have found.

There seems to be a good chance the new CUNIMA 2 (due out any second) will be a favorite. Up to 2K (which the nanoFLASH doesn't-yet-handle).

1.5" wide, it can go nearly anywhere.

The 2/3 CMOS is VERY good news to some (sensitivity/depth of field).

HDSDI out into the nanoFLASH would be such a SIMPLE, light setup.
