hahahaha!! too funny that's fantastic!

[UncleVanya]

Thanks. That helps.

Try blowing it again, spend some time on it . You most likely get it off, otherwise buy a Sensor gel stick.

At f22 and having to enlarge it in order to see it at all I don't think I'm going to lose any sleep over it. I'll blow it out from time to time and keep it as clean as I can, other than that I'm just going to take pictures, like this:

[niceshot]

there you go, now you know the answer, it doesn't matter

[JimC1101]

Yeah, the blower is really great. It usually only takes 2 shots to get them all off. On the picture that still shows the spot in the OP's after shot, how often are you really going to notice ? If you are at F22 at the blue sky, sure maybe you will notice it and zoom to 800%. Just shoot at F16 and you will most likely see nothing.

[Zephos]

That kind of spot is really easy to fix in PP too.

[Aaron28]

nice!

[emalvick]

The "nice" thing about spots is you only really notice them in situations where it is relatively easy to fix them (cloning or healing). Once I start getting dust spots, my own experience has been that I can never fully remove all the spots. I usually end up with one elusive spot, and I just live with them.

Just so everybody knows ,I used 91 percent isopropyl alcohol and a q-tip and then used five more to remove the evaporation marks and I swear it improved the image and the noise performance . So please don't be afraid , scrub the baby . BUT use the damn blower First. These sensors are more resilient than you think. Believe me I scrubbed the daylights out of it. Oh and whilist I was in the cleaning mode I removed my focus screen and clean it with soap and water , so I HAVE A SPARKLING clean Focus screen to look through.

[niceshot]

You better clean it

[dakight]

I have used a Q-tip too, but I used it dry with very light pressure after I had blown it out first. Afterwards I used the blower again. After that treatment I couldn't find any more spots.

[niceshot]

Yup , q-tips are the way, but don't tell too many people that they will be horrified. LOL

Bothered by a couple of dust specks inside of my K3, I elected to clean the camera with a fairly powerful dust blower. I am bewildered by the resulting mess left behind. No amount of blowing will clean it up. So now I am ready to wet clean. Niceshot's recommendation goes against most of what I have read, but it makes sense. I have a bottle of 99% Isopropyl Alcohol and a bottle of 99.9% Methyl Hydrate. Which of these (IF EITHER) should I use on my K3 sensor?

I think you should use a sensor cleaning kit if you are confident in doing so. You can buy these online. Personally I would avoid any DIY suggestions.

If not, you should ask any reputable camera shop to clean it.
