That's worrying. Could you post a picture of the sensor marks and also what was the start of the serial number of your camera?

3821xxx Although the original test shots I took showed a very small single spot to one side of the frame at f/32, I just wasn't worried about it, as I never shoot smaller than f/16 and it simply wasn't a problem. The marks that have appeared are near the centre of the sensor. First shot, no...

I'm a newbie on this forum and have been following this thread with great interest. My K5 was purchased just over a week ago and has serial No 3822xxx. After carrying out the suggested f22 shot of a white sheet I find there are just a couple of marks which, at 100% crop, look virtually indentical to...

If your K-5 has the same problem as most of us, then you cannot remove these marks by cleaning, as they are under the aa filter which lies over the front of the sensor. I would advise you to return it as 'unfit for perpose' and ask for a refund. You have not posted your location, but if it is in...

@Monobod Thanks for the advice. I am in the UK and bought the K5 from a Pentax Pro Centre so I would expect them to adopt the same admirably professional approach to the issue as Chris Harland of SRS has on this forum. I am delighted with every aspect of the K5 so would not be interested in any alte...

Yes indeed, the Canon G10 had a recall because of lines across the sensor, but fortunately mine did not have the problem. These things happen, look how many cars are recalled for various reasons. What matters is how the customers are treated.

I wonder if these are appearing after the sensor has got hot from use? Oil or whatever becoming more fluid and spreading?? Just a thought.

Just done another check, and yes, I have them too. Not as bad as others, but they are there. Put it under the Sensor Scope and the sensor appears clean. Looks like it is going back. :(:(:( However, before it goes back. I am going to give it the rocket blower, just to make sure, and take an F2...

Barrie, RAW won't affect whether you can see the marks or not. Have you cleaned the sensor? Maybe you could post the photos in question?

Well, it is not as bad as some I have seen, but there does appear to be a cluster of small blobs central to the sensor with a couple of others that look a bit like dust bunnies below them.

The D7000 does have an odd "hot pixel" effect during video (not all D7000 examples). Nikon have responded immediately announcing a firmware fix? No other tech issues reported. Nikon did not respond immediately with a firmware fix, it has taken them a month since the first reports to actually ad...

Kr Sensor Marks?
I bought a Kr yesterday and had a test. Then I found the same problem with the K5 sensor. I made the mirror up and found no dusts. Should I return it and ask for an exchange? Do any Kr owners have the same issues? Regards, Liang

Kr Sensor Marks?
Could be dust which you can't quite see. That doesn't look problematic to me, the spots are tiny and not patterned. Looking at thread on the other forum, Falk Lumo checked his K-7 and found a couple of suspect marks apparently under the AA filter - he had presumably not noticed them until this issue...
