Sensor cleaning
The slightest mark will be worse than a speck of dust. Tell me about it :roll::roll:

Dust on sensor?
I presume this is dust, the blob below the moon? First time for me so how do I safely get rid of it please? In the camera that is :)

Dust on sensor?
This shot will need saving in Photoshop of course, where a quick cloning will remove the spot much more easily that it ever was to retouch a darkroom print. In the camera try the dust removal system if you have a model with such a facility. The next step is the Rocket Blower, used carefully. The ...

Thanks John, that was quick!! The K-m has a "Dust alert" function but shows nothing and I have tried the dust removal system too.

Did you follow the user manual on how to perform the dust alert shot? There are a few things you need to take in account.

Point to a blank wall at the highest f-number and overexpose the shot, all the dust will show on that photo then. You might get e abit nervous of all the specks you see then. :wink:

Dust on sensor?
Hi Andrew it's mirror lockup time. Take the lens off then turn the camera back on and go to the dust removal section and look for mirror lockup.Use a rocket blower to blow the sensor when you think you've gave it enough turn off the camera. Re-attach the lens and all should be back to normal.I...

Yes that looks like dust on the sensor. Make sure the battery is well charged before blowing or cleaning.

Dust on sensor?
Thanks to all. As a test I tried running 'Dust Alert' with the lens cap on. This produced after quite a long time a white image with what I assume were dust specks showing so I ran 'Dust Removal', the specks had moved and were less in number. A blower is on my shopping list!!

Dust on sensor?
dont use it with the lens cap on, the cap is suppose to be off and pointed at a white back round that is all you need, and i would not recomend a blower to many people scratch thing with them ie the sensor or in my case the focus screen, i recomend this, it works a treat. http://cgi.ebay.co.uk/Du...

Dust on sensor?
A good large bulb blower doesn't have to be placed very near to the sensor so there should be little chance of scratching anything. It's certainly safer than anything that does normally touch the sensor.

Dust on sensor?
Scott, I have tried the white paper test and there is one speck just about where I would expect it to be, as in my image above. However, despite much sensor rattling it refuses to budge. It's not likely to be duff pixel is it? :( Pete, I will try the blower as soon as I can lay my hands on one.

Dust on sensor?
It can be some dirt which is really stuck to the sensor. I would then resort to a blower but with a blower you risk blowing dust behind the focus screen. I do use a rocket blower and if the particles do not leave willingly I take out the arctic butterfly.

Dust on sensor?
Here is the image from the camera's dust alert. It's the larger blob that's the problem. Should I be able to see it with the naked eye as nothing is visible looking directly at the sensor with a magnifying glass.

Dust on sensor?
i doubt you will be able to see it, and i have dust up in the eye piece from using the blower on my k200d.
