Latest model of Canon cameras
It looks a bit small to hold even 4x5 film! What kind of movements
does it have? In rec.photo.equipment.large-format wrote: : For current and future users of digital photo cameras. : http://digitalphotocameras.blogspot.com/ -- ------------------- Keep working millions on welfare depend on you |

The same damage sould be happening to almost all P&S digicams today (instead it would be the sensor getting burned), as the sensor is always exposed to allow live-view on the LCD and/or EVF. I remember our local camera store (and this is a small town) had at least two people come in who had a hole burned in the focal plane shutter of their Pellix. As for current P&S models, most of them I've seen have some kind of cover which covers the lens when the camera is turned off. I don't know...I use a DSLR and don't really care about EVFs. |

Complete utter and total nonsense from a well known troll.

Fair enough, but I'm curious about the (slr styled) EVF cams. Most of them don't seem to have an external cover that can slide across (and protect lens and sensor). So if one were careless enough to leave it lens-up in bright sun I wonder if damage may result? Is the shutter of the Pellix cloth or metal? |

The Canon Pellix, EOS RS and EOS RT were a realy good try at ultra-highspeed photography using the existing shutter design (used in other Canon SLR cameras at the time) and tended to suffer the accidental shutter damage which Randall described. I was just wondering if EVF cams with fixed (non-rectracting) lenses suffered similar damage to their sensor if left lens-up in bright sunlight. My two primary cameras are both DSLR cameras, so I have no first-hand experience of current EVF cams. |

But I know that these sensors don't particularly like to be pointed at the sun for very long. Is the shutter of the Pellix cloth or metal? That was too long ago for me to remember. |

But I know that these sensors don't particularly like to be pointed at the sun for very long. I have a gut feeling that the Bayer CFA could get burnt unevenly off the sensor surface, leading to some funky looking images. Or it could just burn a hole into the sensor, just like the shutter of a Pellix. Is the shutter of the Pellix cloth or metal? That was too long ago for me to remember. I did half-heartedly Google for the answer, but couldn't find a definitive website that would say one way or the other (metal or cloth). |

As for two weeks, you can see that we're patient and hopeful, but both patience and hope eventually dissipate.
