If it is dust trapped between the sensor and the filter, although disappointing, for me it’s not too much of a disaster. (My K-5 is also affected) My main worry is if it is some form of surface contamination then it could get worse over time. We will have to see what Pentax have to say about this.

There are also few photographers who spend much time shooting white paper at f22....I can't remember the last time I did that. :) I know what you're getting at John, my own marks would be difficult to see on anything other than white paper, or a clear blue sky. However ... some people have large...

A user on DPR has posted actual photos of the marks on the sensor itself confirming that it is on the underside of the AA filter (he used a Raynox 250, and presumably a micro focus rail): http://forums.dpreview.com/forums/readflat.asp?forum=1036&thread=37101106&page=3 (3rd post down).

To be honest, it is not as bad in my ones as in others but I am pi***t of as I spend nearly £1400 and would expect something that has had a proper QC. Pentax CS said to me that "we become aware of a small number of problems" and that I could send the camera back for a replacement if it is effecting...

Canon have also had sensor problems in the past. Shit happens. It's just a shame its happening to K-5 owners this time. I am content to wait and see what Pentax say to SRS. I can still use the camera meanwhile, after all. It's not that the sensor has packed up completely.

f22 on a white wall with flash should be pretty simple - I use this regularly for checking dust.... Bret Not everyone does that on a regular base, so it is understandable if someone is not sure of what exactly to do. Also the flash sets the speed of the camera too quick as ideally you want a bi...

Noticed this thread re a D7000: Perhaps the issue is with the Sony-supplied sensor and is there on D7000s too. Or maybe it's just a manufacturing thing that can affect any body. That looks like regular dust to me

Well still no sign of my K5 today due to the postal backlog caused by the weather so must check this on arrival, however I do have concerns regarding the current situation. This is my first DSLR I can safely say that whatever the case may be with my sensor on arrival I shall be sticking with the K5...

I would love a K-5, but there's no way I'd buy one until this one's died down. It does feel like Pentax has a death-wish, sometimes. Just as they come out with a world-beater, we get a monster QA-fail. :( Who puts the filters on the sensors, Pentax or the sensor manufacturer?

K5 will not fire!
Hi all I know this is a settings issue but could someone just walk me trough it where in the settings I can tell the camera to fire even if the picture may not be sharp or the exposure may be wrong or too long. I try to see if my sensor has the problems and try to shoot a white paper with a pre-se...

If your doing the test to see if there are marks on the sensor it would probably be better out of focus.... i.e. focus set at infinity.... you don't want to pick up any marks on the paper. I've not got a K-5 but I presume you have to set it to MF.

K5 Poll
I am planning to get a K5 when I'm back in the UK over Xmas. However, the issues with the sensor have got me concerned. I thought it might be useful, for potential buyers, to get some idea about the scale of the problem by starting a poll here. More detailed observations (how serious the sensor m...

I have checked my K-5 and it has the marks on the sensor – also tried cleaning the sensor with a arcticbutterfly brush but as expected it made no difference. The marks only showup at f22 and I wouldn’t have noticed them but for the alerts posted on the forums. I will contact Chris at SRS and let...

As a matter of interest, has anyone with a dirty sensor tried using the 'dust alert' function (p. 341 in the manual)and did the marks show up on the screen?
