Damn it. First time out fault with camera ...
Discussion
Been out today and taken 600+ Pictures. First time i've used the camera apart from a few pics in the garden.
Nearly all the shots were of flying aircraft and every single shot has these marks. One is pretty evident and the others less so. I've just mailed Jacobs about it with some of the pics showing the problem.
Difficult to see the other marks with the low res image but they are fainter versions of the 'main' mark.
Anyone seen anything like it ? Is is something I can hopefully fix ? Bit gutted really ..
Cheers

t if it has... I would take it back to whence it came and ask them what is wrong with it. Thanks Olly. I know what you're saying. I just didnt expect to have 600 images with this problem on a 2 week old camera after at most 5 changes of the lens. And those were performed in the kitchen.
Is this the case with DSLR's. Do you have to have the sensor cleaned every 2 weeks after only shooting a few pics in the house and garden ?

The camera should have been perfectly clean when you bought it but no great problem to get it cleaned. With normal use you might need to get it cleaned once a year. Is this the case with DSLR's.

A very dusty place or if you change lens ofter then it will be more often, but not much.
I only clean a couple of times a year even shooting 200,000 photos a year.

I stick the vac over the open face about 1/2 inch away, not advised but really works well for me 
It's a Dyson. The camera may end up inside it ! Not had an answer from Jacobs yet. I just dont really want to go messing about with the Cam. It's looking like it may have left the factory with the dust and I dont want to write off my guarantee.
OK now I'm starting to get a bit annoyed. The Camera arrived on the morning of Saturday March 27th.
I'd been to pick up a new car so arrived home at around 11:50. Had a cuppa and unpacked the camera. Went into the garden and took some pictures.
The picture count on the first picture is 753

I can't see the Exif information for you example shot but it would be interesting to know the aperture setting for the shot.
FWIW I was taking some experimental shots yesterday with little interest in the lens settings and noticed a fairly large number of dust spots in the 'blank' sky areas that I had not particularly seen before. (You won't usually see them in typical shots but large plain areas like the sky can make them obvious.)
When I checked the Exif information I found out why I could see them - f28.5 aperture is pretty much bound to show any dust somewhere in the optical chain in front of the sensor. It's also not the best aperture for the lens anyway so I would not normally be anywhere close to that setting, hence not seeing the marks before. My Canon body is set to auto-clean at start up and shut down. It's last (and only) non-auto clean would have been about 18 months ago around the time I bought my Artic Butterfly cleaning device. So that probably about 10,000 activations or a little more. For reference, I'm not especially careful about dust avoidance when changing lenses.
If you are seeing the marks at a much larger aperture - say f8 or maybe f11 - then you may well need a clean. If they are persistent spots (i.e. they don't move after a self cleaning cycle) that is mot great for a new camera but bear in mind that the problem cannot be fully resolved even with a fixed lans camera. Anything with a removable lens system runs a higher risk I'm not sure about Pentax but Canon recognise this and have a special function for capturing Dust Delete Data that can then be used in conjunction with their software to automatically correct dust blemishes. Other software products provide the Spot correction tools for the same purpose but not usually automatically.
From my point of view - if I plan a trip to shoot some planes or similar I will probably give the sensor a clean but for other tyopes of shot I don't feel the need at the moment. Then again having invested in the cleaning tool I sometimes feel that I should be using it just to justify the investment!
Some thoughts, for what they are worth.
If your f-number is big try a shot of the sky at a much smaller f number and see how that looks. (Also, when shooting skies, double check that the spots are not distant, out-of-focus birds!)

Thanks. Excellent reply :-) OK I'm learning all the time here. It's visible from around F7 ( just depending on background ) all the way up to F32.
On the F11 to F16 shots they appear as round smudges. This worried me a lot.
I've just had a look at a shot of a Hurrican taken at F32 into a very bright sky and low and behold their are 2 very sharp little specs of dust !
The camera has some kind of test for dust but reports all clear.
I dont want to knacker my camera but how do I get rid of them ? Should I be sending it back as it's new ?

Does that mean they've sent you a display model (or second hand/return)?The box wasnt sealed but everything looked new. Their were no finger prints on anything but how can they explain the image count ?
Guess they dont answer mails on a Saturday because I'm still waiting for an explination.
