The scene in John's image is exactly right for HDR processing. It has extremes of light and dark areas and HDR is used to bring those extremes closer together. Great image.

The story I heard was exactly the opposite, that Pentax refused to supply Jessops. This was at a time when it looked as though Jessops were about to go down the tubes.

This can happen if the lighting was fluorescent tubes etc. as the colour temperature and intensity of the light is constantly changing.Whilst on a model shoot on Saturday, I took two pictures less than a second apart on my K-5 without moving the camera at all and without adjusting any settings.

I wonder why, when you have such a sophisticated camera, you choose to use the 'green' mode? In that mode, it's little more than a point 'n shoot camera. Try a different exposure mode for a while, starting with Av mode. Set your white balance to daylight, ISO to 100/200 for daylight shots, and go from there.
Turn off auto Ev Comp, turn off auto ISO.
In green mode there are too many variables that can change.

Something doesn't seem quite right here. The two images clearly have been exposed differently and the light intensity would appear to be very similar in both, yet the EXIF data shows the same shutter speed, aperture, ISO, and EV comp for both images.
Irrespective of which metering mode was chosen, the EXIF data shows them to have identical exposure information, yet they are clearly different.
Is it possible that one of the images has had some kind of 'auto' correction applied?
Can you check the EXIF data in the source images and tell us if they are in fact identical?

OK, I can see the part that concerns you.
If this 'artifact' is due to the sensor, it's almost certainly one of only two causes.
1: sensor dust, pollen, etc.
2: sensor stain
Sensor contamination, or 'dust bunnies' as they are sometimes affectionately known, can easily be eliminated by correct sensor cleaning. A sensor stain requires it to be fixed by Pentax or their repair agent.
To check for either, take an image of a clear blue sky or plain light coloured wall at a small aperture, f22 or smaller.
There are plenty of posts on here dealing with sensor staining, use the site's search facility.
If this artifact is only present in images taken with one particular lens, then there must be an issue with the lens. First, try carefully cleaning the front and rear elements with Eclipse Fluid and a PecPad. If that doesn't clear the problem and it's within warranty, return it to the supplier for repair or replacement.

I think the OP may have sorted this by now. The original post was made 3 years ago.

If you are referring to the greyish blobs in the sky/sea area, they look as if they have wings to me. I'd say they were sea birds in the first pic, gone in the second.
Both images look sharp enough to me with narrow DOF in the second. perhaps a higher shutter speed should have been used, or a tripod. 1/160th is not very fast for the first one.
You might also consider upgrading the firmware of your camera to V1.13
