I have a Nikon D70. It seems the sensor has a lot of "stuff" on it. I was wondering what you have used for the easiest and safest way to clean it. You can see the problem best with a high f stop and long exposure.

I've had very good results with the brushes from Visible Dust. Whatever you do, don't try to blow the dust out with compressed air. That will most likely force it deeper into the body.

I prefer not to touch my sensor, or anything inside for that matter. For dust and specks, i have a small bellows blower thing that i find does the trick. I've been lucky enough that i've been able to easily remove everything that has gotten on my sensor witht hat little bellows.

Are you sure those things aren´t on you lenses?

Sometimes they are, but sometimes they aren't. When i was in Asia, i had this annoying hair like thing, similar to the picture above, that as time progressed, looked huge, like a pubic hair.... (gross), but when i flipped up the mirror, it was a very tiny fleck of something, no bigger than 2mm in lenght...

I would and have taken a series of steps depending on how bad the sensor booger is. First I would recommend the bellows/blower thingy. It doesn't contact the sensor so it's the safest and quickest.

If that doesn't work, then I would definitely go for the Visible Dust brush. It touches the sensor, but it's fairly safe as long as you don't stab at it!

Lastly, if none of those work, I use the
Copperhill Sensor Cleaning Kit:

I think they sell a brush type thing as well, but I have never used it.

Anyway, this is the most risky thing since you will be touching the sensor. However, the SensorSwipe tool is cut for the size of your sensor, so it all works real well.

I spent a couple of days in Utah where it was very dusty. Even though I only changed lenses a couple of times, I had some dust on there that was attached. The Eclipse fluid and the pec pads on the sensor swipe was able to remove it, but it took about an hour total. You don't want to rush these things. The slower the better.

Good luck! Of course you can always send it to the manufacturer if you don't feel comfortable doing it yourself.

not a recommendation on how to clean the sensor but just to let folks know that the Olympus DSLR's have a built in dust removing process for the sensor. Essentially, it shakes the sensor when you turn on the camera and the dust is held in a collection tray that will never need to be emptied under normal use. There are other less attractive aspects of the Olympus cameras (namely the ridiculously costly lenses), but that is a really nice feature that I'm surprised Canon and Nikon haven't picked up on.

came across this somewhere on flickr i thought...

yeah my D70 has the same crud, constantly. i thought i had done something wrong, until seeing all over that dust continually creeps up in these things.

just noticed that the link above is an article that mentions the same link above, "visible dust". :)

These are great, thank you.

Yes, It is definitely not on the lens - a major pain.

I would have just bought a compressed air blower and tried to shoot it out.

I change lenses frequently and usually in a hurry. Besides getting another camera - are there any good ways NOT to get as much junk in there?

Remember, you aren't touching the sensor. You are touching the low-pass filter in front of the sensor.

You can safely touch them with brushes or pads intended for sensor cleaning. That is perfectly safe.

Pec pad on a chopstick and methanol.

Alternately, a soft brush that has a bit of charge (so the dust sticks to it).

@seanich:

compressed air == BAD! if you're talking about the canned air, that has propellant that could coat your sensor. a big air compressor i would think would be too powerful. i'd be afraid it would damage something like the mirror's workings.

the [preventive] method that works for me is to make sure i do two things when changing lenses:

- turn the camera off
- have the body facing lens-down

i still get some dust specs occasionally, but not nearly as bad as what i had before.

Great preventive tip, I never thought of it but it makes perfect sense to change lenses that way to keep eyery thing cleaner!

Here's a decent hands-on review of the Copperhill Sensor Sweep.

I use the cooperhill method, pec pad on a homemade stick and eclipse fluid.

Final Sensor Cleaning Stick

I think it is important to note, you are not actually cleaning the sensor, but the hard glass covering the sensor. Using the proper materials, such as pads and fluid designed for cleaning optics, there is very little risk to cleaning the glass in front of the sensor. The bigger fear is that you add more dirt then you are trying to remove. That's my big concern, scratching the sensor is not a concern at all. It would take something abrasive to damage the glass in front of the sensor, but using the proper optical cleaners avoids this.

I did the "Brush Your Sensor" thing ...it took a while to find the right kind of brushes and then to get all the glue off of 'em. The thing is, they still don't get the stuck-on bits of dust off the sensor. Now I've got the CopperHill stuff.
