Are you absolutely sure that's not birds?

Please tell me your joking?

No, they are not birds...they are on every shot tested in the same place with different lenses.
And yeah, I seem to have gotten a very "pearly" one...that's what I get for trying to get the first K5 in Canada.

Wow that's pretty bad. Do you remember the F stop or thereabouts?

Hope that they take care of you....they should

Oh Great! Now mine has it too!

Just got on the forum to ask about buying a flash and now I have Sensor Pox (aka S.O.P)... hopefully it is not the forum...

Anyway, don't have a lot of time to devote to it at the moment, but I did just pop outside and took some sky shots at different apertures...

Sure enough, at ISO 80, f29-f8 on my 18-55 wr kit lens and with my DA 40mm 2.8 I get them right in the middle of my frame... and if you know where to look, on mine, they are noticeable at ALL apertures, but most egregious from f8 and up... I will do some more shots later and post my findings.

Funny, didn't notice them before, guess the shots I have been taking are busier and wider open... but needless to say, I will be pursuing this with Pentax... as another poster mentioned, "it's not acceptable".

I will also post my findings from my contact with Pentax about the issue and hope others might do the same. I trust Pentax will want to rectify the problem pronto with those of us that didn't wait for all the bugs to be worked out of the camera. That way, we will keep reporting all the GREAT things about the K5.

Cheers!

I am convince now that some of the camera do have a severe issue, that the one with the string of point. Some have minor issues and that the one with single point and light .
Now , my position will be to sent a a registered letter to Pentax (in Country were camera is bought and dealer ) informing them that you have a defective camera and include a photo of the defect . Informing them that you expect they resolve the issue but in the meantime your intention to keep the camera but you could returned at any time.

Aperture was 22 / iso 100 / shutter 45

as far as i'm concerned there will be string of Pentax k5s refurbished and available at a lower price.

MrPetkus · 12-08-2010, 07:17 PM

It's amazing that so many forum members were quick to trivialize and/or discredit, often in a snide, mocking tone, those who first reported this. Folks weren't given the benefit of the doubt but instead were treated to chest-beating remarks akin to Live with it Crybaby or Don't be such a Wuss.

Always good getting things in perspective. I remember controversy over the K10 too, and it has ended up serving me very well. Seems I shouldn’t be overly concerned getting the K5.

Thommo is a fine chap. From what he reports, the solution is a new A-A filter, so the repair shouldn't be too hard. And that Pentax received faulty A-A filters from a third party manufacturer.

Leica handinspects, under close scrutiny, many products that leaves the factory. But guess few of us would be willing to shell out the extra for it.

Is this reliable information?
It isn't in line with what Pentax told me.

BTW, AA exchange is not easy. To replace the K-5's AA filter by a dummy costs about 480 Euro.

Hi Falk,
I’m just citing what Thommo stated, in the link from earlier in the thread :
Flickr: Discussing K5 problem in Pentaxians

“It looks like all they need is a new A-A filter, so a repair would not be hard. It's just a bit of glass.”

“He said it appears likely Pentax received faulty A-A filters from a third party manufacturer.”

Maybe for a big corporation it is possible to get the prices down, compared to what we as private persons would have to pay to be without the AA filter.

I believe the Leica M8.2 is an example of a camera that is though roughly checked before leaving the factory. But then we’re talking 3-4.000 $ camera. Don’t think many Pentaxians would go for that set-up instead. Then people would likely prefer to have a camera sent back under warranty.

Seems Thommo is taking it in stride :
“I'm not losing sleep over this - but it looks like I'll be back to the DS for a while - and that's not necessarily a bad thing!”

Those Aussies got a relaxed attitude at dealing with issues.

nanok · 12-09-2010, 03:43 PM

jonson: that sounds like pure speculation, rather than actual statements/information. if you followed falk on the issue, you probably know that, by now "we know more" thanks to him.

point in case: most people (me included) tend to think of the sensor as "silicon sensor + aa filter thinggie". few people realize the (optical) complexity involved, or they don't stop to think about it if they do have the knowledge.

i'd chalk it up as gossip (with all due respect to an aussie shooting a ds

)

Take a look at all the Sensor Stain threads in the K5 forums.

The photos shown in this thread pretty much confirm for me, no problems. I think I've been extremely lucky with these Pentax cameras. I never seem to experience the issues that plague others.
