Cheers for the comments, they were shot on a tripod but it was on sand and it was fairly windy so that probably didn't help the cause.
Noticed the dust spots once I'd put them on here, think a clean is in order
ahh i didn't realise...i just discounted slow shutter because the sky actually seem's pretty crisp...i thought he'd gone for a low f stop and focused on the sky
He shot at up to f29 guys - it's the shutter speed at fault 1/8th sec on some - assuming handheld that's the problem

Silly question.....if the lens you used has any sort of vibration dampening it should be witched off if using a tripod....fell into that myself......
