I can find another photo if you like. I did find uploading the jpeg and viewing them on the website made them a smidge less obvious. On my laptop and desktop computer, they are reasonably obvious I think. Some other photos have it too, some a little less obvious, but definitely there.
I ended up taking the camera to the shop I bought it from and showed the sales rep the photo (and some others) on my laptop. He seemed convinced there was something up

. There was a suggestion from another rep about a possible problem with the sensor (maybe that's the same as your thought Kym, about the beta models..?). *sigh* so, it's back to CR Kennedy to see what's wrong.
Yes, I have used a different card, thanks for the suggestion. I even put the card in another dSLR and it's working fine.
I'll post again, when I find out but it will be a few weeks away.
