[Dust] Blow job defeat
For the first time since early 2005 I'll have to get my sensor (Maxxum
7D) 'wet cleaned' as my half dozen attempts with a blower simply won't get a few stubborn specs off of the sensor. Local camera store does it over a 3 day period (or 24 hours for a rush premium). There goes my long standing assertion about never needing a wet clean. Probably I just let it go for far too long (last blower cleaning was last summer) and some specs "welded" themselves to the sensor over time. -- -- 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. |

Why don't you buy a wet cleaning kit, with Eclipse or whatever it's called, and DIY ??? |

For now I'm getting ready for a trip and the same store is ordering me a few bricks of 35mm and 120 film as well, so... -- -- 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. |

I have wondered why, however the other co's haven't simply bought the Oly technique under license. -- -- 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. |

I have my doubts as to whether it's as effective as the ultrasonic method of the Oly. Still, certainly better than nothing. (I believe the later Sony's do this as well, that is the "shake" method). -- -- 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. |

Yes, that's the problem. What is the mutually agreed upon standard for cleaning? I also love people like you who talk about not having to clean one's sensor for a long while, while never describing the conditions one's camera sees. Exposure to dust is one criteria. However, in my experience exposure to moisture is another. Does one ever expose the camera to an environment where moisture might condense on the inside of the camera, or on the sensor? I have found this to be a situation which many times leads to instances requiring a wet cleaning. And I do use cameras and lenses which are considered to be sealed in such environments, Nikon D200/D300 + 70-200 f/2.8 IF VR + others. My problem here was waiting too long to dust out the sensor. In the meantime the camera saw various cycles of temperature and humidity as well many, many lens changes. Entirely my fault as I said in the first post. However, had I checked at least every 3 months, I'm sure I would not have had a problem. The natural range of humidity here is 40's to 80's with saturation peaks over the course of the year, though usually drier in the winter. However, I don't believe there was ever condensing humidity at the sensor. (When I come in from the cold I leave the entire camera bag in a large plastic bag for a few hours). -- -- 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. |
