I Hate Dust And dust removal does not always get it off.

But we do have a fog of ice crystals this morning. Quite
beautiful, despite those stupid spots on my pics! (I don't have
this issue with film!!!!! Then again, I don't have to wait hours
for my pics, either.)

I don't know if you're serious about dust or just wisecracking, but
if you're serious what you're seeing may not be dust. The image looks
very much like/identical to a phenomenon I've experienced before in
extremely cold weather. Looks exactly what shows in your images: a
ring around the sun with two large bright spots at the circumference
aligned with the sun.


You can see exactly what he's talking about in this one.

Just above the central tree that has the sun behind it.

It might not be on the senso. I've seen these kind of spots from dust on the rear element of a lens. Easy way to figure it out is to shoot up into a clear blue sky. Then change lenses & shoot again. If the spots are in both images, it's on the sensor.

If it's the sensor, there's plenty on the list who can tell you how to go about cleaning it yourself.

Personally, I find it more convenient to just take my camera back once a year to the independent camera store where I bought it and have their tech clean the sensor. Since I bought the camera there, they don't charge me for the cleaning. Regularly they charge $35.00. It would still be a bargain even if I have to pay.

The Pentax O-ICK1 cleaning kit is $44.95 from Adorama, but it's also on indefinite back order from Pentax.

I understand all the arguments for doing it myself, but on the other side is the fact that the camera store I use is insured. If I screw it up, I have to pay out of pocket to get the camera fixed.

If they screw it up, their insurance covers the cost of repair.
