Landscapes are funny things. Often, atmosphere can be a problem. When the air is not crystal clear, you can get a slight fuzziness to a photo. The lower the ISO you can shoot at, the crisper the picture may be. The Olympus lens is a little slow, but using a tripod would certainly help. Don't forget that light can really destroy a photo. If the degree from brightest to darkest is very extreme, you have to make compromises with the exposure. That is why overcast days offer some of the best, even-lighting conditions in many circumstances. Using a neutral density filter may help even out the scene. Automatic metering does not always choose the best exposure. Some work better than others. You could try using a grey card for the initial light reading and go manual. Which leads me to my last though. Whether shooting in digital or film, exposures are relatively cheap. Bracket every shot you think is a winner and shoot as many images as you can. When you get back home, one of those exposures will be the best for the shooting conditions.
