Although good DSLRs have sealed bodies and often a sophisticated ultrasonic cleaning mechanism on the sensor, you'll anyway run in dust problem after some time. This time interval could be very long, since dust enters when you change lens, and many people use always the same zoom. But if you have many lenses, and you take many outdoor pictures, dust will inevitably lay down on your camera sensor.

Step 1: the swarm of flies

Effects of this bad attitude of dust are not much noticeable, but when a bigger dust grain will come to keep company to his fellows, you'll notice it and you'll probably want to close aperture to 22 or more and take a shot to the sky. Then you'll become frighteningly aware of the affair magnitude!
I knew dust was becoming a serious matter for my dslr, but I took this shot for curiosity during my last travel on mountains, you can imagine my astonishment when I've seen a swarm of flies around the sky in my picture!
<p>Excellent! I'll have to try this. Are you not in the US? The tool you used as a handle looks like an exacto knife holder to me. My camera is old so its not that big a risk. Here's hoping it works.</p>
<p>Just be sure to not use silicone paper tissue, since it leaves a remains on the sensor.</p>
<p>I'm from Italy, good luck with the cleaning process, you will bring your camera at new life!</p>
Nice instructable...but I would not dare to touch mine ;) - okay its not true :)
lol :-)
execellent article---be extremely cautious of ethyl alcohol- <br> i h ave used a cotton ear bud --trimmed flat ---+ tiny drop of- <br>methylated spirits---yes---that purplish type----very light pressure on sensor-circular <br>movement ----watch out 4 static dust!!--- <br>good results--my eos 550 has self cleaning mode however--let it do the job if <br>u got butter fingers----- <br>manufacturer knows best--- <br> nb--my first camera was a leica m1--circa 1958---older &amp; wiser- <br> keep your digital away from RAIN1----THE ultimate destroyer of integrated micro <br> circuits <br> regards--- carl---
Thank you for writing this! <br> <br>It is a really great help!
I'm glad for that! :-)
When cleaning optics, the best procedure is to make one pass only with the lens paper, and then discard, after each wipe. I would use ethyl alcohol. It evaporates more slowly (an advantage). As long as you follow your procedure of not allowing a drop of liquid to fall (shake off the tool before wiping), you need not worry about getting liquid in the electronics. You don't need lightning-fast evaporation. Do not touch the lens paper where the alcohol is applied. That will dissolve finger oil and deposit it on the sensor.
Yes, ethyl ether evaporates really too much fast... <br>I forgot to mention about not to touch the paper, it's indeed very important! Thanks, I'll add that.
.........or (for $12) you could get the cleaners that are specific to your sensor size, and not handle volatile solvents
Very clever solution to make the squeegee! <br> <br>Many modern camera have an IR/UV Cut filter / dither filter over the actual sensor. They also might include a mechanism dust removal mechanism that shakes this filter. <br> <br>My recommendation is to first try using an anti-static brush and canned air before falling back to solvents. But for an older camera that's really dirty, this technique is awesome. <br> <br>Search for &quot;BrushOFF Sensor Cleaning&quot; for the anti-static brush. They are crazy expensive though.
bella andrea ho appena fatto ed &egrave; venuto ottimo!
fantastico! :-)
EXTREMELY useful! Thanks for sharing!
Thanks ynze! :-)
