DUST: Does this rule out buying DSLR's?
I have been reading the review of the Sony DSC-R1 on Ken Rockwell's site
http://www.kenrockwell.com/sony/dsc-r1.htm and I see that the conclusion is that you are better off with a real DSLR like the Canons or the Nikon D50. But it has always been the potential DUST problem that has put me off DSLRs. The advantage of the Sony DSC-R1 is that it has DSLR quality 10MP photos and a fixed lense, so I guess this pretty well eliminates the dust problem? One site that discusses the dust problem is he http://photography.about.com/library.../aa122903a.htm I know of only one DSLR that advertises that it has "solved" the dust problem. This is the Olympus E-300 DSLR, which has an innovative way of preventing dust entering an SLR when swapping lenses, etc. Apparently, a supersonic wave filter generates very high speed vibrations to remove the dust from the CCD. The dust is captured on a special adhesive panel inside the body. This function operates fully automatically at start-up, but it is also possible to activate it manually. I wondered if any users of DSLRs could comment on whether the dust problem is significant enough to rule out buying a DSLR and thus go for a fixed lense 10MP quality camera like the Sony DSC-R1 instead? Also, does the dust system employed on the Olympus E-300 work well? If it does, would the E-300 be the best bet in DSLRs if you are concerned about the dust problem? Thanks for your advice Jim F B |

Thanks for your advice Jim F B Lots of people have bought DSLRs and seem to use them. The old film kind also had dust problems, I've scratched a few rolls of film. Nothing's perfect, if you wait until it is, then you'll wait a long time. |

If you are regularly using your camera in dust laden conditions and will be frequently changing lenses in those conditions, yes this could be a problem. But the same problem existed with SLR film cameras. But if you are like the majority of "hobbyist" photographers you will rarely (if ever) have to change lenses in a dust laden atmosphere. Most of the time dust will be a non issue. If you are concerned that your camera may have come in contact with dust to the point that some may be lurking in crevices on the exterior, you may want to carry a can of compressed air to clear the exterior seams and then place the camera in a closed environment (like a large ziplock bag) where the lens change can be performed without any "windborn" particles being propelled into the open camera body. On the other hand I have never gone this far and have yet to have any dust particles on the sensor. I have had a few settle on the mirror, but that is much easier to clean. I just try to get out of the direct wind (in some cases just turning my back to the breeze and sheltering the lens change with my body). Unless you are changing lenses in a sand storm, a drafty haunted house (with loads of dust swirling in the air), or a wood shop next to the belt sander, you probably will do fine. True, a P&S camera is much more resistant to exterior contaminants but the reason many of us gravitate towards SLRs is the flexability that is afforded with replaceable lenses. Where are you going to find a P&S camera with 100+x optical zoom which I have with my array of lenses. Also since the SLR tends to attract the higher end user the range of manual and semi-manual functions available on an SLR camera body tends to be more extensive than any single P&S camera. So if that flexability (lens and settings) is important, SLR is the way to go. If not, you may be perfectly happy with a P&S. The decision is up to you. BTW, I used "SLR" in the above to refer to both film SLRs and Digital SLRs equally (when practical) as most issues effect both formats equally. Randy ========== Randy Berbaum Champaign, IL |

I think the dust "issue" is way over-hyped. I've noticed it maybe twice in the almost-two-years I've had my 300D, and only as off-color blotches on otherwise solid blue sky (quite easily fixable with most better photo-retouching tools) when shooting airplanes. A quick once-over with a lens brush does the trick every time. Yes, it can happen... but I wouldn't consider the possibility a major influence for your buying decision unless you plan to shoot a lot in sand storms and dust devils. --- avast!

Does this rule out buying DSLR's?
I hope you never wasted money on a film SLR as they get dust in them
too. Or if you did, I hope you never used any film which is a dust magnet - quite literally. It has to do with water impurities, negative ions and gravity plus some other things you obviously never thought about until you read something written by a hack writer who has obviously given the matter no more thought than you have. -- http://www.chapelhillnoir.com home of The Camera-ist's Manifesto The Improved Links Pages are at http://www.chapelhillnoir.com/links/mlinks00.html A sample chapter from "Haight-Ashbury" is at http://www.chapelhillnoir.com/writ/hait/hatitl.html "Jim F B" wrote in message ...

But the same problem existed with SLR film cameras.
Well, not exactly. Every time you wound the film on, you had a fresh 'sensor'. I do shoot in dusty environments, and I have never, I repeat never had a problem with dust on film *at the time of imaging* in all my old SLR's. Later, yes...! That's one reason why I am waiting patiently with my prosumer, until a decent no-dust design arrives with a good low-noise sensor of at least 8, preferably 12 Mp. The Olympus cameras are almost there, but not quite... |

Thanks for your advice Jim F B You could lock the new camera in a dust-free, vacuum case, with 1/2-inch thick glass walls, and just look at it, or you could do what the rest of us do, use it and clean the damn thing now and again. This reminds me of the many laptop owners who complain about grotty screens, not realising that it is their own grot! |

But it has always been the potential DUST problem that has put me off DSLRs. Dust is actually less of a problem on a DSLR than it was in film SLRs. Film cameras would get dust on the pressure plate which would leave huge scratches on the film. The DSLR does not even have a film plate. I and my Nikon D70 currently live in the tropics. We have weathered typhoons, dust storms, high humidity, and very hot weather. I change lenses constantly and I take few precautions to protect the interior of the camera from dust. You know what? I sometimes get dust specks on my pictures. You know what else? I get fewer of them than I did when the camera was new and I babied it constantly. I have learned that dust specks will sometimes show up, that they are only visible against a solid color background and therefore easily edited out, and that they rarely stay on the sensor for more than a few shots. I don't even bother to clean the sensor any more. |

If you see dust on your images you can clone it out pretty easily. You'll need to learn to clean the sensor but once you've learned this it seems no more complicated than cleaning a lens. I was just in Africa on a 2 week photo trip and at one place the dust was so thick that I'm getting a surgeon's mask before I go back (seriously, my wife coughed up dust for 2 weeks after we got back ... it coated everything). So we got dust on the sensor almost daily at this place, but it only took a few minutes each night to clean two cameras. On the other hand I've spent two weeks in Alaska and never had to clean the sensors a single time. To me, bottom line is that dust is a nuisance but definitely NOT a reason to pass on a dSLR. You can clone out most dust spots pretty easily and you can clean the sensor in a few minutes when that becomes necessary. Bill |
