How do I shoot a landscape, I start with aperture priority, ISO 100, f5.6 to f11 depending on the depth of field or the distance from near to far objects in the scene, evaluative metering 80% of the time, between 17mm and 300mm, the above examples show both extremes, I will almost always use a GND filter and or a CPL, I always use mirror lock up and a tripod with a remote shutter device. There is no one lens for landscape, landscapes have there own individuality, typically a wide angle lens is used for those big panoramic scenes, but I love to isolate individual elements like a tree or a mountain peak and that can mean using a 300 mm lens or a 70-200 mm lens. When shooting wide I will reach for my 17-40 f4 L.
