I am a little suspicious of a woman who "makes her living as photography [sic]" having problems like this. I'm even more suspicious of a professional who doesn't know how to avoid, minimize, and correct a problem like this. So, given the camera doesn't have dust-control internally, what would you suggest to avoid dust, a changing bag for lenses like changing film in cassettes of a large-format camera? I shoot primes with my D200, Nikon has antistatic coating on the AA filter, it is not the sensor you're cleaning, and this seems to work well, 2 blow outs in a year, that is it. Change lenses all the time and I'm not all that careful about the changing. There are several other similar threads going around, looked at my last picture with sky in it, cranked levels, clean at 200%. Tom That's great for you, but does this reduce the importance of those who have had dust problems? Besides, the Canons (not Nikons) have been known for sometime as dust magnets, especially the 5DI think someone who is reporting their direct experience with dust is far more valuable then someone reporting on what their read someone else said. If you were to tell us you had problems with dust we could ask questions and get a better idea of just how bad the problem was. Instead you tell use that someone else, who you don't know, had reported that they have problems with dust. But from what they wrote it is hard to tell just how big the problems they are having really are. As an example if you are the type of person who checks for dust by shooting the sky at f/32 you are going to find a lot of dust a lot of the time. If on the other hand you simple use you camera and worry about dust when you see it starting to show up in your images you will likely have a lot less problems. You don't see to want to accept that for most of us dust is simply not an issue, even those of use shooting with Canon camera and changing lenses often. Scott |

I could picture the Dyson ad but couldn't quite come up with the name. Don't know if the latter two qualify as magnates yet, but certainly dust magnets. -- john mcwilliams |

oups.com: I would think that any lubricants on the sensor (well cover glass) would put a fair bit of haze in the photo. Not with a thin film The dispersion should be quite minor, and the AA filter is already dispersing a little, anyway. For what it is worth I notice a big differance between shooting at f/ 16 or lower and f/22 to higher. If I insisted on being able to shoot at f/22 I would no doubt have to do a lot more cleaning of the sensor. But I very rarely find the need to show slower then f/16 so life is good. It would be nice if cameras had real user-programmable modes; then it would be easy to keep the lenses in the f-stop range that you really want, in an auto-exposure mode. I can not use Av-pri when I am shooting birds hand-held in low light, for example. I'd rather shoot at ISO 1600, in Tv-pri-mode, with a generous positive EC to get an exposure index of about ISO 800 when light is sufficient, and suffer a bit of under-exposure when the light isn't, without getting blurred images. When, however, I catch a hawk or eagle flying above in open sunlight or against bright clouds, any change of mode would mean a lost opportunity, so what I wind up getting is too low of a shutter speed, and too high of an f-stop, emphasizing any dust or oil on the sensor. With true user-programmability (and I can't think of any excuse for cameras not having this, after years of digital cameras), I could fine- tune a mode for my lens and uses, trying to keep the f-stop in a certain range, limiting exposure time, and increasing ISO for lower light levels, and then perhaps letting the lens open up all the way at a certain point where under-exposure causes more loss of detail than wide-open optics. Dust could become a much more minor issue. Happily, once I removed the lubricants from my XTi sensor, it hasn't been collecting dust like it used to. I haven't had to clean my XTi sensor in about three months now (I have read warnings of XTi coatings coming off with eclipse, though; I don't know how true they are). My 20D is a nightmare for dust; even with a 1.4x TC attached almost permanently, it still gets an occasional big fiber on it, usually about 5 shots into a day of several hundred shots. It seems to be the mirror stop deteriorating. -- John P Sheehy |

Never did I call this guy a liar, I I merely pointed out that your assosiation with him makes you the worlds stupidist man, either that or you actually made that post on DP Review just to make some sort of idiot point and that would make you a dirty lying scumbag idiot, probably makes me equally an idiot for even replying to such a stupid post.
