Hi Evan. I think that Tom has explained it well - that's a very versatile camera. The stacked powermates will give you 12.5x nominal and probably about 15x actual, so your fl will be over 20m. You need that much if operating the chip in full frame video mode. If you select to use only part of the chip at native pixel resolution (about 4 microns) you will need much shorter focal length and the 6m that Tom uses gives an angular pixel resolution in line with that used by others. Regards Ray
