This makes the most sense in applications where the sensor is incredibly expensive and the aperture array can be made more cheaply.
I could imagine some applications in doing high speed optical data transmissions where there are multiple end-points.
An impressive 5 Fn buttons? Aargh! These things are more a curse than a blessing. Who can honestly remember which function was allocated to which button? And what you changed it to last?I would be much more impressed with less Fn buttons - just put the things that are needed onto well marked buttons and the rest of the stuff into the menus. An Fn button is effectively just a badly marked button IMHO.
As long as it takes NiMH and similar 1.2V rechargeable AA's and treats them properly - that is the biggest fault with its competitors like the Canon SX150 - they all seem to view a 1.2V rechargeable as a very flat 1.5V Lithium.
Great to have video review - really helps with appreciation of how it handles. It would be better if the camera was turned on and pointed at a scene and then a photo taken - to see and hear the actual operation of the machine. A long boring exploration of features would not be great, but an expose of the most innovative features and the most annoying would go a long way towards making a decision for the potential buyer/user.
