G11 Best aperture for landscape ?

I know that small aperture will give greatest DOF but I recall reading somewhere that small apertures on small sensors can give problems.
I will shortly be spending 5 days on a once-in-a-lifetime trip and I want to record the scenery to the best of my ability :). The shots will include foreground (other people) and distant background (mountain ranges !) and hopefully some stunning scenery in between.
So, is there a "sweet spot" in terms of aperture, focal length and focus that I should look at using?
Many thanks.

Its not so much the small apertures on small sensors per se, its more that the lenses designed for small sensors tend to be physically smaller - which means that so is the physical size of the aperture at every setting. For this reason many small sensor cameras have a minimum aperture size of f8. (smaller apertures tend to produce less sharp images due to diffraction as I guess you know from your question.)

DOF is a function of physical size of the aperture so in a camera like the G11 larger apertures (e.g. f5.6) may do the job for you although in a 35mm format camera I would normally use f 8 at least. You can also maximise DOF by using hyperfocal focusing - so instead of focusing at infinity you focus at a closer distance such that everything from around half that distance to infinity is sharp. As your lenses are not marked for this you have to guess however and use trial and error.

Many smaller cameras are optimised for their wide open aperture.

I don't have a G11 (yet ;)) but I would suggest you go out and take some shots and see what settings work the best for you to get the desired results. As already stated though compact cameras have a pretty large dof so it's probably not going too matter much. There may be an aperture setting that yields sharper images. I know on dslr lenses this is true but am not sure about compacts. You may even find the landscape scene mode works for you which would make things easy.

Hi Peejayw,
Somewhere, I'm not sure where, I read the sweet spot on the G11 is F4.0 to F4.5.
I do shoot at these apertures, but, if I was you, and time permits, then I would take several shots at each location at differing apertures anyway.
This is what I do when I shoot waterfalls at several shutter speeds, as often when I get home and upload my pictures, the one I thought was a sure fire winner turns out to be a dud when viewed on a large monitor.

There's no fool like an old skool fool :D

f8 - which is the minimum aperture.

If you're thinking of diffraction; it usually occurs on very small apertures

I've always thought in the f4.5 to 5.6 range and I've read that. I know the engineers will say it doesn't work that way but apparently someone working for Canon informed a friend of mine that the f8 on her G10 was equivalent to f64 on a full frame camera, I do know the things have amazing depth of field and why I love them for close up flower work when shooting fairly wide angle, the combination of the two can be amazing.

FWIW, I find this true with my SD960IS. It's sharpest at f/2.8 (widest)....Nice Blog BTW
