Everytime i wet clean it takes ages. The first few passes always makes it much much worse but about 2 hours, half a bottle of eclipse an entire packet of pecpads later i can usually get it down to "only a few blobs at f/22".

I'll admit its a process i dead doing and my 550D and 70D need it every few months.

I believe you are "hitting the wall" or the "point of diminishing returns". It should not be a "marathon" or even that difficult. If you can't see improvement after 3 or 4 swabbings, then it's best to just leave things as they are and come back and try again the next day.

There are several "dry" tools that may help you out such as a good static-brush, SensorKlear pen or gel stick. This would allow you to concentrate your wet tools on the middle of the sensor, staying away from the sidewalls by about 1mm or 2mm. Then you can use one of the dry tools to go right around the perimeter.

Most people see their bottle of Eclipse last for many years, so I'm not sure where all of that fluid is going. Is there a possibility you're using too much per swabbing?

Blowing and dry i do even more often but eventually it needs wet. After 3-4 passes its far worse than before starting and usually requires another 10-15 passes to improve it from the starting level.

Once i get blobs noticable at f/11 or so and i cant dry clean them then i go with wet.

My guess is that you have a camera that has excessive lube and that makes your case unique and not representative of the average user experience. Might consider sending it in and **** about that specifically.

Take a pic of clear sky at F22. It will look like you can plant corn in that crap.

You be the judge. Just did as you stated. Here is one of a relatively featureless gray sky day (just taken) and then another, same portion of sky, but 3 stops "overexposed."
Yes, I do see some bits of dust, but not enough to plant corn. :lol:

And this is my 5DIII, which has seen little use in the year and a half I own it. And I have never cleaned the sensor. Just relied on the built in cleaner.

(3 stops overexposed on meter in AV mode) with nothing blown out, at least according to the histogram.

Count your blessings for you have the Magic Camera of Antiock. Until now it was thought to be a myth. Alone you must face the peril.

I took it into Photoshop and ran auto-levels. I can count 35 to 40 dust-bunnies plus that rectangular bit of debris.

Nicholas, I just took both images and did the same thing. I see the long slash on the bottom left, but barely anything else. Perhaps I'm just not seeing it.

agreed. but two does not make a minefield. And that's a year and a half old camera that's shot perhaps 5,000 pics, if that, but has seen many, many lens changes in all sorts of weather and has never had the sensor cleaned by hand.

I'll try the auto sensor cleaner again and see if it's able to remove those two offending spots, which as I'm sure you know are easily cloned out in PP.

I took the top photo into Photoshop and just ran auto-levels. Don't bother with the second image, the first shows at least 35 dust specks. But if you only see two, I'm not sure why.

Okay, I've done as you stated, Nicholas, and I do see many more.

So I'll close with this, and then maybe post a few real world pics.

When I last shot a model I owned a Nikon D3. As I think I stated above, I hated it. I saw the dust spots all over the damn pics and as I suck in PP, I could not even attempt to get rid of them. While I do on occasion shoot landscape at f22, in real world pics the majority of those are just not visible so really nothing to worry about as far as I am concerned.

Yes, that was an eye opening test. But as Roger from lens rentals just pointed out when testing a camera that had light leakage, he said don't smirk if you don't own that camera (and I'm not suggesting for a moment you are doing that) because every camera leaks a certain amount of light if subjected to the crazy test that he subjected it to to prove it.

I have posted many pics here recently and of all the comments, and there are and were many, not one has ever been "clean your sensor." Though I may now. :lol:

Next I'll take the same f22 pics with my 1Dx and see how bad/good that one is.

You can buy the swabs from PhotoSol w/o assembly. Why go through all the extra work? :)

Because at 45 dollars plus shipping for a 12 Pack you have to be insane. I can buy a nice Super Tak lens for 45 dollars.

Nope the durable swab stick and replaceable pads is the way to go. VASTLY cheaper.
and really easy to use. ...

I started with PecPads and Eclipse but switched to Visible Dust static brushes for my primary cleaning pretty quickly.

I use the pre-packaged pads (from Photographic Solutions) now because:


  1. I rarely need to do a wet-cleaning.
  2. I only do 2-3 passes (i.e. 2-3 pads) per cleaning.
  3. I always worried about contaminating the PecPads while I was forming it around the spatula.
  4. It takes forever to wrap each pad which makes an already long/stressful process even more so.
Cheers,


Geoff S.
