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?
