At a wide aperture, light rays that pass through the dust spot are coming from
ALL OVER the lens from millions of different angles (left, right, top, bottom,
etc) and there are a million little dark spots which are spread out amongst all
of the other light
and smaller. At 2.8 they're so out of focus
they don't register. Is this right anyone?

The dust spot isn't right on top of the sensor - it's right on top of
the fromt surface of the protective piece of glass (and anti-aliasing
filter). If the piece of dust is smaller than 1/2.8 times the thickness
of that piece of glass there's plenty of light

Hi Bob,
It's almost certainly not beneath the filter - if it's right against
the sensor then changing the aperture doesn't make it disappear (it's
the distance between the dust and sensor and the lower angle of the
light that makes the dust disappear as you open the lens aperture).
Depending

It's probably just a dust spot that's clinging to the sensor. It may be almost

Thanks for the suggestions as to cause.

I've had better luck with swabs and fluid than with the Pentax

Get a Rocket Blower or something similar (DO NOT use canned air) and

As we know, the K10 implemented some measures to keep the sensor dust
free. Do we feel that the sensor shake and adhesive strip are doing
anything to reduce dust problems on the sensor?

It helpsa wee bit. Taking care to not expose the camera when changing lenses
helps much more.

My technique for this is simple: get the next lens that's going to go
on ready, take off the lens with the camera face down, and keep it
face
Nope. That's how I do it. And I rarely see any dust on the sensor.

Actually yes. I'm quite
The K10D's ultra-smooth coating and sensor shaking dust cleaner seems
a little crude but it works ok. I don't think about it too much in
practice. At wide apertures, a bit of dust on the sensor is often
difficult to see and not a bother unless you're working with smooth
open sky. If I'm
You can choose to have the Pentax system run every time the camera is powered
up. And the K20D version seems more effective than that of the K10D. I've never
encountered a dust problem with the K20D, regardless or aperture or background.

Yes, I tried that. Unfortunately, I find it takes three or four
passes of the shake function to truly get all the dust off the
sensor, so having it run at power on doesn't actually cut it for me.
I have no experience with the K20D. Let me know how it's done after
20-30K exposures. I'm

Simply put: No
I still need to get some E2 so I can clean
That's 250-300 exposures a week, about what I do on average too. Been
a little slower these past couple of weeks, as I've been working on
some different things.
Sounds like the K20D is doing well for you. :-)

Hi Bill,
I fooled with my camera a bit. I couldn't get the menu item to grey
out. I did have one spec of dust on the sensor, and after a couple of
tries with my hand blower, I got it out
Hi, I've been playing with the dust alert function on my K20, and have a
question that hopefully
someone here can answer.
I am following the instructions in the manual regarding lens type, etc, but can
rarely activate
the dust alert.
Usually it is greyed out and unavailable.
Does it only
No. It works whether there is dust or not. However, it's kind of
fussy about the background you focus against. It has to be neutral
and uniform.
