don't use a prime but i take most of my landscapes at 10mm on my 10-20 lens.
)May as well ask what's the best f-stop
Hmm, from what I understand it, if you want as much in focus as you can get, the f-stop chosen depends on two factors: 1) What f-stop is your lens sharpest at, and 2) The hyperfocal distance.
For the 10-22, I've heard that it's sharpest at f7.1-8, and there's really no reason to go above that. That answers 1).
For 2), the hyperfocal distance at 15mm and f/8 is about 5 feet. This means if you focus the camera at about 5 feet in front of you, everything from 2.5 feet to infinity should be in focus.
See here and here.
I'm fairly sure that what DD was getting Theo is that you don't always want max DoF. Each shot, person, style and situation is different.![]()
And you only get Acceptable sharpness in other areasSo if you're going to stick at f/8 for everything, then always focus somewhere from 2-9 feet ahead.

Basically, I have yet to see a wide lens shot of something (say, a landscape shot) which warranted anything less than a max dof...
...have you?
Sure I have, the nearest I have of an example to hand is this shot. Not superwide but the principle is the same.

i wasnt specifically about talking about 1-4.5 feet, but infinity
