What aperture are you shooting at? You probably already know it, but for landscapes you'd be looking at f/5.6 or so unless you're hurting for light. Popular notion is that at f/11 only will diffraction start to affect you, but with modern high resolution cameras diffraction starts to creep in as early as f/9, so f/5.6 is generally best unless you really need the deeper field. You're probably going to be fine at 24MP, though.
