The method revealed many black dust spots. Taking the pictures with a different lens did not change the result. So, I have to clean the sensor. Do a Google search on sensor cleaning. There are many methods, but it requires a light touch. A lens cloth or any other material will certainly leave lots of dust on the sensor. So you need the right cleaning materials. Most camera stores sell sensor cleaning kits. I just ordered the Delkin SensorScope system (http://www.delkin.com/ products/sensorscope/sensorsystem.html) which is one of the method advised on the www.cleaningdigitalcameras.com web site (advised by Savageduck) This system was advised on many other web sites so I suppose it is good. The advantage of the system is you can magnify and see the dust on the sensor so you can directly check if the it is clean. Thanks for helping. |

Here are the links to the pictures I took with my 2 different lenses (18-70 digital zoom and 80-200 classical zoom) My camera is a Nikon D70. The dust stays at the same place. http://webpollux.free.fr/public/43AB...0_70mm_f22.jpg http://webpollux.free.fr/public/43AB..._200mm_f32.jpg |

It is always best to make an educated decission and have the information from reliable sources. For the most part taking care when changing lenses will keep dust off the sensor. Yes, I used to changing the lens in the street taking care but not doing it inside a bag. Indeed, this makes the difference. Personally, I believe the Delkin system is one that is more an expensive tool box addition, than necessary tool, nice to have though. You are perfectly right but I live in France and we are in a very paradoxal situation: We have a very poor choice of sensor cleaning products (even in a big city like Paris where I live) so we have to go to specialized shops. Unfortunately, because there is not a lot of concurrency and because foreign products are over-taxed by the French customs, the price are very very expensive. For example, the Delkin system is around 225$ in France whereas I found it around 100$ in the USA. Even with adding the shipment price and the tax, I will pay around 100 euros in France. The most basic cleaning system I found in France was around 60 euros so I prefer spending 40 euros more for the Delking solution. And I think the Delkin's magnifier idea is quite good ! https://www.micro-tools.com/ Thanks for the links and all the advices. Any way take your time and be careful cleaning. Be aware that DSLRs are vulnerable to dust, so change lenses carfully with that in mind and you will find you may only have to clean that sensor once or twice a year. I never cleant my lens and I just noticed it was dirty now (I bought my camera 4 years ago) At the begining, I had a few spots but now, it waste all my pictures. Have a good Easter WE. |

Hi again, I discovered that Nikon offers a dust correction system called "Image Dust Off" coupled with the Nikon Capture 4 software. You take a reference picture from the camera (you have to take the picture at 10 cm from a white screen) and it serves as a reference for eliminating the dust on all the subsequent pictures. In order to do that, you have to buy the Nikon Capture 4 software (unfortunately, you have to buy it so I just tried it). Another constraint is the picture has to be stored as a raw NEF picture (Nikon picture format) in order to be processable by Nikon Capture. The results were quite good when I applied it on my dust test picture. BEFORE DUST OFF: http://webpollux.free.fr/public/6a3c...e_dust_off.jpg AFTER DUST OFF: http://webpollux.free.fr/public/6a3c...e_dust_off.jpg But the results were really bad when I applied it to my cushion's picture as you can see below: BEFORE DUST OFF: http://webpollux.free.fr/public/6a3c...e_dust_off.jpg AFTER DUST OFF: http://webpollux.free.fr/public/6a3c...e_dust_off.jpg Consequenlty, I won't buy the Nikon software and wait a few days for receiving my sensor cleaning kit (a physical action is always better than a software one) I have no idea why my results were so bad for the second test whereas they were good for the first one = I suppose that it is due to the picture complexity in the 2nd case. |

How can I remove the dust which came inside my lens ?
Uzytkownik napisal w wiadomosci
... Hi all, A few weeks ago, I noticed that there was some dust on my lens (this is the original zoom provided with the Nikon D70 camera) so I used a really bad quality rag (I did not know it was so bad as this time) to clean the lens. Unfortunately, some small pieces of rag came inside the lens (and came between the lenses). Actually, I do not know how to remove the dust which came inside. I do not want to disassemble the lens because I am pretty sure I will not how to reassemble it right. Moreover I am afraid of adding some more dust doing this. Now, I have plenty of dark spots all all the pictures I take ! Does anyone have an idea which could help ? Thanks in advance. You can keep the lens as it is or there is only one solution - professional service. Don't try other methods. Marcin www.gorgolewski.com |

Hi, my Tamron 24 mm f 2.5 Nikon FM mount, which I used with my Nikon FM-2, I left it over in my basement-flat in Kozani (where I was studying, in northern Greece) which was very humid. The result was that fungi developed inside the lens. The vendor (a good friend of mine too) said we could cover it under the guarantee and I had it cleaned for free. I strongly recommend you seek professional service, at least *they* have the responsibility. -- Tzortzakakis Dimitrios major in electrical engineering mechanized infantry reservist hordad AT otenet DOT gr |
