The N86 is all about revolutionary mobile photography unlike your SE evolutionary mpx races.
Focal length decides whether your image will be wide-angle or not. Correct me if wrong, most cameraphones are F=4.78 (equivalent: 35mm, like most common entry level PnS). In comparison, the N86 has a 28mm wide-angle lens. This simply means the objects in N86 shots look further (which means more area can be captured) than in those SE shots. This would be EXTREMELY useful if the N86 has had optical zoom on board.
All your Xenon equipped SE cameraphones have fixed aperture size. The N86 has adjustable aperture size (f2.4/f3.2/f4. three stops. This means the size of the hole through which light enters in the camera can be changed on the N86 to suit the lighting conditions and this will affect the exposure of the picture. Aperture variation is preferred over ISO adjustments as the latter may introduce noises and such. Aperture variation directly affects the amount of light entering the picture. Thus, aperture variation CAN allow for more flexibility in shutter speed adjustments without changing ISO (i.e. degrading the picture quality). For example, you can set aperture size down a stop (i.e. to a small numerical value) and shutter speed up a stop - the exposure remains constant, ISO value remains low, but you get faster shutter speeds. If the aperture size were to be fixed, then you will need to increase ISO in order to increase the shutter speed OR use exposure compensation to get the desired shutter speed and exposure combination.
The N86's camera is so much more than any other cameraphone on the market, closing the gap between cameraphones and digicam, if Nokia does this right, the flexibility and functionality (NOT gimmicks like smile detection or blink detection) of the camera may just surpass PnS. YET, it's not getting as much hype it deserves. Crappy Nokia marketing. By good marketing of the N86, I mean photography jargon like aperture and focal length should become understandable by the laymen, such that people APPRECIATE what the N86 can do. | |

Hey, STOP talking facts in here  I don't know why - all of a sudden I feel sooo sorry for . . . SORYERICSSON And not to mention - the N86 uses the most popular OS ever ! OK, OK, after Windows that is. S60 rules

the only real revolution is variable aperture size which sounds half sweet half bitterly
f/2.4
can catch 36% more light than f/2.8 which means more power in low light - unquestioned advantage
f/3.2
nothing new
f/4.8
wide depth of field, huh? that's fine for normal (non-macro) photography but what about macro? I see problem here if aperture size will be dependent only on light amount. I hope not and focus distance will be important too. if not then I don't see narrow depth of field and nice bokeh effect
another strange thing from the N86 tech spec is "max shutter speed: 1/1000 sec". I would like to see higher shutter speed instead of f/4.8 but ok, better depth of field and blah blah...
I'm waiting for more camera samples
