The Dust Alert command in K20D Setup Menu is unavailable for me to select. The command is there in the menu but it's gray and I can't select it. My K20D is running v1.03--I think. I can't remember how to display the version.

Why has this happened and how can I get the Dust Alert back?

Thank you.

William

Looks on your SD card. It will have a saved picture file from the last time you ran the Dust Alert. Delete it.

I wasn't aware of that, but I do know that Dust alert won't run if you've got a manual lens mounted.

wtf is dust alert?

DigitalGal · 07-30-2009, 03:00 PM

This is right. You'll get a dust alert option grayed out with a manual focus lens mounted. If you put on an af lens, it's in function again.

To check the firmware version push the menu button while you turn on a camera.

To add to the above, the camera must also be set to autofocus. The dust alert setting is greyed out on manual focus or using a manual lens.

Hmm, I didn't realize Google was down :-)

Oh, very well, it's a mode in some cameras where it will show you on the rear LCD where any sensor dust is. Much like shooting the sky at f/22, but it processes the image to overlay a picture of the sensor and generally make it more clear how to find the dust speck.

come on dude, sarcasm!

i dont use the feature, because it picks up dust that doesnt even show up in the image. I dont even bother with the start up dust removal.

like you said, a sky shot at f22 is enough, then if i see anything i just wipe the sensor.

It does not appear when you're shooting with wide open lens. Believe it or not, but some people are shooting landscapes at f/8 or f/11, and some even do macro shooting at f/22 and smaller

Thanks for all the responses--you guys are great.

I had deleted the file from the SD card. The first time I ran Dust Alert I was using an auto-focus lens. When I tried it yesterday I had my A-series normal lens mounted. I'll check the menu again with the auto-focus lens this evening.

Thanks, too, for the guidance on checking the version.
