i pity any fellow who took ur advice :cry:
do u know those lens pen have carbon coating on it?
ur lens is probably >10 times harder than the coating on the sensor...
in fact coating on lens are found behind the front element

even fluid on those soft cloth proves to be abrasive, not to mention dry carbon.

Huh? :eek:

Where the h*** did you get this very wrong information?

Lens pen can be used only to clean lens surface not sensor surface

I would send it to the service center to clean it. Hassle-free, trouble-free and confirm safe. CSC only charges about $21. I'd rather pay 21 bucks than to risk having the whole camera unusable but thats just me :)

No! No! No!

please be careful with what you suggest to use a lens pen to clean sensor. even you have done that and have good results, but does not mean other people will.
there are many disadvantages with using lens pen (or sensorklear)

1) does not help with welded dust

2) if you have plausible abrasive dust on top of your sensor that wasn't removed by alternative methods, you are going to rub it happily against it

3) that said, while the hot pass filter is actually not as wimpy as most people think

please google

"sensor dust"

there are many methods out there; so far the one that is most popular among diy sensor cleaners involves

1) eclipse or e2 solution (check photogrpahic solutions website which one fits your camera, please make sure you do)

2) sensor swabs

3) or pec pads to replace the sensor swab paper

all from photographic solutions, easily available at major camera shops

it is best that you get someone with the know how to demonstrate to you how to do it, probably with his own camera, and then you do it. if you have no confidence, then do not do it, it is not a task that everyone can feel confident with. and of course, if anything happens, remember, it is due to your own incompetence.

that said, i have cleaned sensors myself since i started the hobby, and nothing has ever happened.

Some interesting reading:

http://www.sensorcleaning.com/what.php Interestinbgly, METHANOL-based products (Eclipse) is NOT recommended.

This person has had claimed long-term usage of the lenspen to clean the high-pass filter: http://www.sensorklearreview.blogspot.com/

According to this site, Canon has been seen to use the Lenspen to clean high-pass filters: http://www.cleaningdigitalcameras.com/methods.html

OK, now I'm really confused!

i have had no problems so far with eclipse or e2,

there is actually documentation of cases where some people put too much solution on the sensor swab and the solution ends up seeping UNDERNEATH the filter, that is really super win.

anyways, i have had the misfortune of trying out the speckgrabber listed on the link before, it is horrible and does more harm than good, very exasperating to use also.

and yes, i think i've seen that site that claims that lenspen can be used to clean sensors, i have also tried it before and nothing went wrong, but i won't use the method more than thrice. i'm sure those with experience with lenspens will tell you that they become increasingly effective - i suppose the fact that you are after all, using a surface that you cannot clean to rub the same thing.. so many things can happen.

someone once told me about a guy (i hope he isn't around) who used a screwdriver with a pec pad wrapped around it to clean his sensor. the end result was a scratched filter. :sweat:

Ultimate WINZ! Should try a penknife to scrape off those super stubborn wleded spots! :devil:

Oh, speaking of Eclipse, I was told the same thing, and advised to put on very little on the pecpad, or wait a few seconds before swabbing.

What did you mean by (lenspen) "increasingly effective"?

sorry, typo.

increasingly ineffective. and if you touch the lenspen with your finger, can throw the whole thing away, the more you clean lens with lenspen after that, the more you want to cry, it just spreads oil stains or what all over the lens. imagine what that would do to your sensor. whereas, pecpads and sensor swabs all stand alone.

you don't do your own cleaning yet? :)

yeah, too little is better than too much.. you shouldn't have the sensor swab ending up drippy, that is definitely too much, just two or three drops would suffice actually

there used to be a thread complete with pictures on how to put pec pad on sensor swab, but nothing about how to actually use the sensor swab (though it is quite intuitive and there are many videos on the net i think).. not sure if it is around since we are discussing this.

ah yes it is:

I gues if one really wants to use a lenspen, should have one exclusively just to clean the HP filter, and use it only for so many times before relagating it to other uses.

And pass over very lightly, AFTER judicious blowing! I prefer upside down blowing.

Hahaha, 'IN-effective'. You had me a bit perplexed.

Been doing my own cleaning for quite some time, but like any newb, spent too long wallowing in unfounded fear of doing untold horrors to my sensor and got by quite well till the HP filter just got too dirty.

It's kind like changing a focusing screen in a body without that changeability feature; seems scary before, slow the first few times, and becomes a breeze after more practice. :cool:

My best cleaner is the vacuum cleaner. Yes, myself using it. :thumbsup:
I simply bring the vacuum tubing near to the camera or lens and not a speck of dust left.

If you are worried about the camera mirror vacuuming out, or some screws coming out then forget it. :bheart:

are you sure? how close is your vacuum and the camera? the home vacuum or the portable car one? your camera face up or down?

Tried using a micro fiber cloth and the blower... Didn't work for me.
So I used an airbrush, lens paper and some solution that came with my dry cabinet... But thats because i took apart my d70 to convert to ir...
Works just fine for me :) And its not exactly a ccd that your cleaning. Its just a filter. The real sensor is below it.
