I'll ditto Georges comment, istD was a bit of a nightmare, had no problems with any body with dust removal though.

I had to regularly clean the sensors of my K10D and K20D. I've had my two K-5s over a year now and have NEVER had to clean the sensors. Amazing really and I'm pleasantly surprised

I had to regularly clean the sensors of my K10D and K20D. I've had my two K-5s over a year now and have NEVER had to clean the sensors. Have you actually taken a shot of featureless wall at small aperture and cranked up the contrast on the result? If you have, and you've got no dust, I'd love t...

I have had to clean my K-5 twice since I got it. I don't see it as a problem.

It's a lot easier to deal with sensor cleaning than to spot prints. White spots on darkroom prints were a nightmare.

It's a lot easier to deal with sensor cleaning than to spot prints. White spots on darkroom prints were a nightmare. Did they come from specks of dust on the negs? I get lots of white spots on scans if I don't have Digital ICE switched on.

Black dust on negative = white spot on print. It can be dust that adheres to the film during drying and the drying needs to be in a scrupulously clean area. A shaft of sunlight in a room reveals just how much dust is around. Negatives should be cleaned carefully prior to avery use, including scannin...

Negatives should be cleaned carefully prior to avery use, including scanning. Life's way too short for that, if you have Digital ICE on your scanner :)

I know what you mean, it's a slow process at best, but Digital ICE will not see detail that is covered by dust. It's in a way like cloning everything in sight rather than cleaning the sensor. For a quick scan that's one thing, but to do a high quality job then that's something else. It's why I ra...

I bought my K-5 in March (I wish I'd bought one of those posh lenses at the same time, having seen the subsequent price hike). Anyway, after about a month I noticed a circular blob appear on the upper right hand side. It doesn’t vary with lenses or focal length. It doesn’t show up by the Dust Ale...

That is dust Charlie. You can clone it out for now but you will at some point need to clean your sensor. I suggest you invest in an Arctic Butterfly brush. They are not cheap but they do a great job and last a lifetime. When you change lenses make sure you keep the camera pointing down, to minimi...

Thanks Gwyn. I only swapped lenses a few times in that time and thought I was being careful. However, a normal domestic environment is far from dust free and it's impossible to ensure dust doesn't get in. I'm also careful to immediately pack the lens cap because if that gets dusty it can move to ...

I have never had trouble with condensation and my camera has been in and out from a warm ship to Arctic temperatures and back. I think you'll find it is dust. Try running the cleaning program on the camera first, before spending money on cleaning. If it doesn't annoy you too much then just clone...

Try running the cleaning program on the camera first, before spending money on cleaning. Do you mean run 'Dust Removal'? I've tried that. Isn't that run everytime I turn on anyway? Or is there something more sophisticated? Thinking about it, if it were a condensation mark I assume they'd proba...

It isn't stain. That problem has long since been fixed, and it looked very different to what you have there.

dammit! I've just joined the group so I can express my frustration with a similar problem with my k30, just posted my entry and then read this! do we have a common problem perhaps?

One more thing......the sensor has a static charge even after switching off the camera, so best to wait some seconds after switching off the camera before changing lenses to allow the static charge to dissapate.

the sensor has a static charge even after switching off the camera CCD sensors do. CMOS sensors don't use static charge. As said before, a rocket-blower has worked perfectly well for me since the K20D :) Wet swab wipes over sensors was common on *ist-D CCD etc, but no longer! Matt
