Taking pictures with my new K30 and noticed a blob when I take a picture. It is at the top right of the picture. I have cleaned the front and back of the lens. Does anyone know if this is Dust or an oil drop. I have everything i need to clean dust but not oil. Any ideas?

THANKS

Just a dust spot. Use a blower to clean, not compressed air.

That looks like dust to me. Try blowing it off with a rocket blower, then try the cameras dust removal feature. It's a good idea to turn this feature on at startup, as it does a pretty good job of keeping your sensor clean.

Looks like a dust spot. With digital, these are unavoidable due to sensor static and moving parts in the camera. Dust removal feature or rocket blower should be just fine for this. Feel free to search the forums for the many other threads on this topic and read them for more solutions or more detailed instructions.

Thanks for the quick reply I toke care of it with a rocket blower.

It's a dust spot on the sensor, not the lens.

I'll second this, with a twist.

I like having the dust removal feature activate when I'm shutting off the camera. Helps decrease the "startup" time.

Every bit counts!

Would it be overkill to have the dust removal feature on both start up and shut down?

Might be. Just because it takes some time. Also, I remember someone warning against using this feature, they feared the shaking might damage the camera. But thats probably not a real concern, just some paranoia.

But most importanat to have it clean after changing the lens which means on start up should be the most effective.

But then you still have the debris floating about the inside of your camera.. it is going to likely redeposit itself on the sensor or the back of the lens shortly after.. or does the dust removal feature do more than vibrate/shake?

Use Photoshop to heal spots. I travel a lot and my camera and lenses are dusty during travels. Photoshop makes magic!

As a general rule face the camera down when swapping lenses makes good sense to me. Also the debris floating about in the camera, I believe there is a small adhesive area to catch such stray particles but I maybe wrong?
