The PENTAX K3 Mark III is great for landscape photography, especially for an APS-C camera. Its sensor punches above its weight, with excellent dynamic range to capture a wider array of detail in high-contrast scenes and amazing high-ISO performance for low-light or nighttime landscapes. The camera's also incredibly sturdy, with a weather-sealed design that allows you to shoot in all kinds of weather conditions without worry. It just isn't the most portable camera, so it's less convenient to take on long hikes or remote shooting locations.
