Dust alert

I tried a friend's K30 and I could not find the Dust Alert feature. Maybe it's moved somewhere else but I hope Pentax didn't remove that useful feature.

yes, that's history now, I was looking for it on my K-30, but it is not there.
On the other hand, since I permanently enabled Dust Removal / Startup Action on my DSLR's I never had any problems with the dust on the sensor

useful feature
Sorry, I can't agree with that, and If they left it out, it could be an indication that Pentax also realized it doesn't work well.

Since the dust alert feature requires you to point at a uniform color object anyways, stopping down the lens and bumping the ISO will do the same. Low shutter speed/motion blur isnt' going to make a difference since the dust is on the sensor.

Maybe they did remove it - I can't answer that, but as for it being useful, it's not THAT useful.

I never found it useful at all. The dust alert on my K-r would tell me the sensor was clean when a photograph would tell me otherwise. Maybe I just didn't know how to use it correctly, but I don't miss it.

Never found it useful either, always giving fault readings or not showing up the dust, just take a shot with the higest f-number and overexpose a couple of spots, thats the best method.

It's because they don't explain how to use it correctly. I found it very useful on more than one occasion, especially when traveling. I don't have to time to go back to hotel, check on the computer, etc. While my K-5 doesn't often get dust, frequently changing lenses will always get some dust at one point. And since the K-30 doesn't have the ultrasonic dust removal but the poor (and probably useless. never worked well on my K10D and K20D) sensor shake, it's even more useful to check for dust.

I found it very useful on my K20D, it worked well, but since you can pretty well do the same without it, no big deal. Since you can now do the dust removal shake on startup and shutdown, maybe that will help.

Another possibility: Left out to make more difference between K-30 and whatever the next more-expensive-model is.

Probably not, this feature was on the K-x and similar entry level bodies. Pentax could have removed many features before one that costs nothing (it's just software).

Anyway that's not the end of the world but it was an innovative feature they could have improved.
