"if you don't do it correctly and the solution can damage the low pass filter coating"
Not possible. The coating on the filter is on the OTHER side of the glass -  facing down.

accidentally applying it on the edges of the sensor and not being able to remove it all
This is altogether a REAL possibility. However, a re-application will reabsorb any stuck on pieces.....if any.

accidentally spilling the product inside the camera
Not possible if you don't bring the bottle near the camera. I have the bottle opened on a table beside me.
I hold the camera in one hand, and the brush in the other. Until I grow a third arm I will not be able to spill it into the camera.

"scratching the low pass filter with the tweezers as you are trying to insert or pull the "tab" to remove the gel"

This was a concern of mine also. But consider this. I don't use a tweezer with sharp points. Also I bend the strip of paper
when I place it into the corner of the sensor. It bananas up so I can grab it with my fingers. I use my fingers instead.
But try to scratch glass with a tweezer. go ahead try it. I did.... on a mirror. Didn't work. It would not scratch. as hard as
I tried the glass would not scratch.

I'm not sure about all Canon or Nikon cameras but I know that many of the cameras have the coating on the front of the filter.  There are many known cases of people scratching or accidentally removing the coating.

Yeah then its a factory defect

I dont think I will ever use that

First they say its water based , so it cant possibly do nothing with greasy spots , and you will still have to use swab method , and the dust that it handles well , can  be blown away in most times and thats way more practical  and faster method .

So its not a real competition to swab method but for air pumps , and even if you use disco thing you will still want to blow some air cause if you start going with a brush and you have some bigger crap like peace of sand or something you could do some damage.

I just did some research on the low pass filter coatings.

Seems that some wet cleaning solutions (alcohol solvent based) may or may not present a hazard with Nikon cameras with ITO coatings.
ITO coating: D40, D40x, D70s, D80, D300, D2xs, D3
No coating: D1, D1h, D1x, D2h, D2hs, D2x, D50, D70*, D100, D200

However disco film is water based, and will not harm filters with ITO coatings

The only 100% guaranteed way to get your sensor cleaned without worry is to send it back to the manufacturer.
ALL cleaning methods (EVERY SINGLE ONE) has some inherent risk if you decide to clean it yourself.


PS Lizard is correct. Disco film will NOT remove grease, fingerprints, transmission fluid, discarded oil from your last oil change, bacon grease,
Vaseline, WD-40, bearing grease, peanut butter, butter, or margarine.

Perhaps shooting film again might not be a bad idea after all - no sensors

the dangers i think, or negative things with discofilm are..(as mentioned on the sensor-film site)

it takes a long time to do the process

you run the risk of the shutter closing while the stuff is drying and if you mis-applied any of the film the shutter could be glued closed!  THEN you would be in a pickle.

Then what's the point!?   ::)

This method of cleaning scares me - but it could be really great for people who want a really REALLY clean sensor.  I saw the b4 and after - they are great.

Hmmm ... I'm not sure about his method either. And what a performance!

It reminds me of a method that was recommended by certain people a while back, using a bit of scotch tape sticky side down on the sensor. Anyone who did that needed their head examining.

Apart from the other concerns expressed, what does this stuff leave behind? Yes, I know that they say it all peels off but you have to take their word for it. If it sticks strongly enough to need peeling off it could well leave a small, invisible residue behind.

Use it again and again and again and ...  ??

For me the main thing is not to get too anal about dust. A while back, in the UK they were selling a little zip-up bag for lens changing, with sort of reverse gloves (like equipment for handling radioactive waste). The idea was you put your camera and lens into it, zipped the whole lot up and changed the lens in a supposedly 'sterile' environment.

Talk about a laugh and a waste of money. But I bet some suckers bought it and spent their time putting camera and lenses in and out of it while the world went by.

I'm sticking with my Arctic Butterfly brushes and rocket blower.

Dust is a fact of life in DSLRs. Live with it and take photos.

I bought the Sensor-Film, and am pretty happy with it.  I guess it would have been cheaper to go with Disco-film, but couldn't find a supplier (didn't really try), and since hearing about it on the podcast, just went with that guy's product.

It's true it won't get rid of oily / greasy dust - and I've had a couple of stubborn spots like that over the year I've been using this (2 or 3 cleanings so far). 

I usually go with Rocket Blower first, and if it's still dirty, Copperhill, and then finally Sensor-Film.

I'd like to point out I don't like the idea of "bananaing" up the pull tab, as if the battery runs out (hasn't happened to me yet), and the shutter closes, it could get caught in the shutter.  I juse use a tweazer with non-metal tips (found it in the pharmacy).  Besides, the sensor film is so thick, you can't really scratch through it unless you deliberately pushed down and accross on the sensor.

So all in all I'm happy, and I end up with pretty clean sensors.  Handy for those days I plan on doing landscapes.
