Dust on Sensor?
Can the high end point and shoot from Nikon, Canon, Olympus or Panasonic
suffer from dust on the sensor as they age? Or is that just a DSLR characteristic due to interchangeable lenses? |

Technically possible, the things aren't air-tight (otherwise you could use them under water) 0-) Not sure how often it actually happens in day to day use though. Anyway, if it ever does just bung the whole camera on a ultrasonic transducer and it'll shake off again. ;-) -- Owamanga! |

I have never heard of it happening. I Have had my F828 in some pretty
nasty salt spray and no problems, yet. Scott |

Dust remains air-borne, and can become air-borne again after settling on components...while salt-spray is so large and sticky that it won't coninue to float around your camera's internals long enough to make it around all those corners on it's way to the sensor. |

As the water part of the spray evaporates you are left with small air born salt cystals, these bloody things travel for miles, I have rust to prove it. They may well be too small to be notice on a sensor, in small numbers at least. Scott Scott |

Microscopic crystals can certainly travel. But I also agree with your second part, and suspect that only an accumulation would make a noticable difference that might resemble the typical dust spot problem. With a DSLR, the worry would be far larger droplets getting on the sensor during a foolish lens change in the spray. I suspect the salt crystals you refer to would make a difference (damage) your other camera components sooner than your sensor... -But hey--I'm just thinking out loud here... |

And I do worry about damage to the other components as well. There is no way to avoid the salt here so the only thing to do is hope for the best. For the most part I think the cameras are pretty well sealed and I would be surprised if anything much larger then a micron could get in. Scott |
