It's been a while since I've used my *istD, but it's got a green button, and I'm sure it meters when this is pressed too.

Just checked, and yes it does. So that's the easiest way of using it (as far as I'm concerned! ).

But when you click on the 'buy now' link, it just takes you to the Jessops homepage, so it's not actually available at that price.

If you were pedantic, it might be worth ringing them and saying you want to buy it at their advertised price, but they wouldn't be obliged to sell you one.

Dan

No problem Scott, glad it's okay for you now. Hopefully this thread will be helpful for anyone else using the Dust Alert feature.

So, in effect, it's something like this that is supplied with the K20D, rather than a K20D with any GPS functionality?

I think there might be some disappointed people around here...

I usually like rhythm and melody, but every now and again, I get a hankering for just a really good rhythm.

Drum solos have their place.

Are synthesizers better than pianos?

Dan

Didn't think that sounded right at all, so looked it up in the manual. Step 3 of the instructions on page 232 of the K200D manual says:

"Fully display a white wall or uniformly bright subject in the viewfinder and press the shutter release button fully."

One of the points in the 'Caution' section states:

"The exposure time may be extremely long when using the dust alert function. Note that if the direction of the lens is changed before processing is complete, dust will not be detected properly."

So basically, don't hand hold the camera when you're using dust alert. And point it at a white thing, don't leave the lens cap on.

Try it properly, and see how it works. Then if there's still a problem, think about returning another camera.

Just looking at those original 'etch-o-sketch' shots, and they don't look like random patterns, they are line drawings of your room, I'm sure.

Rotate one of them 180 degrees, and crop out all the lens mount part of the image, then see if it looks familiar, with a bit of imagination.

Camera bag (rucksack) on a table?




The dust sensor tool will be expecting you to be pointing the lens at a blank surface, as it will be detecting contrast variations across the scene. Any contrast in this situation will be due to dust on the sensor. If you're not pointing it at a blank surface, it will detect and draw the contrast changes in the scene that you are pointing it at.

I suspect that this might be at least some of your trouble, but I apologise if I'm completely wrong.

Best thing to use is a clear blue sky, but try a fridge door, or a very clean white sheet of paper.

Dan

I would like to point out that was with a fisheye lens...

Just three months? Could be worse, could be married to me!
