Problem with Focusing
As a bit of a newbie to photography I've been slowly learning how to produce half decent shots but have come up against a problem which I can't quite get my head round. When shooting landscapes at an aperture of f16 ish the general advice is to focus one third of the way into the shot to ensure maximun sharpness. But if I do this, as soon as I recompose, the camera refocuses. Should I be switching to manual focus or changing the af point, or is there a simple way to overcome this. It may be that I'm being a bit thick here but it's beginning to annoy me !!

your spot on this is the best approach with the 1st better than the second.
I don't yet know of any camera's that will sort out the 1/3 hyperfocal/rest to infinity is in focus thing.
Also for night shots AF if rarly any good anyway.

You could hold the shutter button half-way down, then re-compose, that should hold the autofocus for you. The downside to this is if you are metering TTL it will usually meter on the point you have have focused on unless you can alter this through your camera's setup menu.

I was going to suggest the same as Marc above. Additionally, some cameras have a Pan focus setting which I think sets the focus at the position which gives the maximum DOF bearing in mind the focal length & aperture in use.
What camera are you using, ****?
On my Nikons, Marc's advice would be spot on, plus you can set the AE/AF button so that you only lock the focus but not the exposure.
On most cameras there will be a variety of different ways of getting round this.

....having said that, I have found that, for landscapes, manual exposure and manual focussing do give the best results, once you are confident in using them. I would say that manual exposure is more important than manual focussing - at f/16 most landscapes should be pretty well in focus from 10 metres to infinity no matter where your AF system is picking its spot.
