Thanks for the answers guys. I understand the points about shooting landscapes in the field, and they make sense. However in my controlled experiments I was, as I say above, shooting my laptop screen from about 3', with the target therefore covering about 1/3 of the field of view. It was tripod mounted with spot focussing aimed at the centre of the screen. In each case I wound the focus out to infinity and the half pressed the shutter button. With LV on the focus got set correctly, with LV off, the focus was off by about 6" as indicated on the focus ring.
I'll have another go a bit later. Can I post videos here?

Having had problems getting this lens to auto-focus correctly (it seemed unable to focus on far subjects, and I've had to resort to manual focus (of all things! :rolleyes:)) on my K-5, I tried this weekend to set up the focus fine adjust. In doing this I found that:- If I try to auto focus using live view it gets it pretty much spot on.
- If I switch to non-live-view then the focus is set, incorrectly, further away. In this case by about 6" at 3' as indicated on the focus ring.
This would explain the problems I've been having with shooting landscapes - it would have been trying to set the focus past infinity. The testing was done using spot focussing, tripod mounted, shooting my latop screen displaying a Moire pattern target on it, as seen here AF microadjustment for the 1Ds mark III, 1D Mk3, 5D Mk2, 7D.
Has anyone else been having problems like this? Is it a 'feature' or a 'bug'? If a bug is there anything I can do about it (apart from buying a new lens and/or camera that is)?

:o I'm afraid I've been a bit of a doofus. I was selecting the Star Shooting item and then pressing the shutter release rather than the OK button. But thanks for the help. I'll have another go tonight and see if I get anything worth the effort.
Thanks guys.

Hi All,
I have just been trying the Astro facility on my O-GPS1 for the first time and I'm having problems getting it to take an exposure of anything other than 1/25s.
This is on a K5 with the 18-135 zoom. I've done the precise calibration thing, set it on B, 2s self timer, manual focus, ISO 100, F/22, and set the timed exposure to 1'30" but it just keeps taking 1/25s exposures. Am I doing something wrong, or do I have a duff unit?
TIA
Nick
