But point at the sun and hold the shutter open in "B" (or set a long shutter period) and it will for sure. Don't ask me where the threshold is, I don't know, but please do experiment from 1/2 sec and slower and we look forward to the result. -- -- r.p.e.35mm user resource: http://www.aliasimages.com/rpe35mmur.htm -- r.p.d.slr-systems: http://www.aliasimages.com/rpdslrsysur.htm -- [SI] gallery & rulz: http://www.pbase.com/shootin -- e-meil: Remove FreeLunch. |

Can the sun damage a sensor?
I think the answer would be "yes" - but not doing any "normal" kind of shot.

The intensity of the sun on the sensor at any given point depends upon focus (especially for wide angles) and f-stop. The lower the f-stop, the more intense the light. Total heat depends on those plus exposure time. There may be a small difference between lenses of different focal lengths, as a small, focused sun from a wide-angle might have some of the heat escape to an area where the sun isn't focused, but a telephoto at the same f-stop would make it impossible for heat from the center to escape anywhere. -- John P Sheehy |

Ah, I think I'll wait for Rich to snag the first ever magnesium sensor and try a 30 min exposure... straight at the sun... at high noon. _____ Slack |

Can the sun damage a sensor?
I've heard that it can damage it from some people and others have said there's no way... ?? In a previous millennium when I shot with a medium format camera, I'd use the mirror up button a lot, (so the flap of the mirror didn't shake the camera on the tripod.) I packed it with the lens up and the next day I opened my case outside and waited around awhile. The wide angle lens on it focused the sun on the shutter curtain and burned a hole in it. That was an expensive mistake cause I didn't know for a week and wondered why I had those spots on all those images. I don't think I'd want to see if that would damage the sensor. I really don't think it would harm it during a normal exposure, but not for any long term exposure, besides the heat that could cause damage, image the damage caused by looking at the sun with your eye.
