The best digital camera for landscape photography obviously is the one that has a high enough minimum lens diameter to fully cover the whole view. It's usually large enough to properly cover even the most generous aspect ration of landscape images, including full-field, wide-field, or panoramic. It's usually not very expensive, either. There are lots of reasonably-priced entry-level digital cameras on the market today.
I would also try to get a mid-budget camera that has decent image processors and a decent LCD screen. The biggest limitation of this sort of camera is the picture quality. But you can avoid this problem by getting an inexpensive speed camera that has just the essentials. This sort of camera will have a higher resolution, and a smaller form factor than other speed digital cameras.
If you're into super-small, super-high-quality cameras then the Pentax K-1 could be right for you. A Pentax K-1 is essentially a smaller brother of the previously famous SLR Pentax camera family. It's got just about every feature that you'd expect from an SLR, but in a smaller, more compact body. For this reason, it's great for photographers who want something smaller but not compromised in any way when it comes to picture quality.
For more professional use, a fully automatic or semi-automatic (with the choice to manual focus and aperture priority) digital camera with continuous shooting features may be the best camera for you. These fully-automatic cameras give you a choice between a first-time Continuous Shooting mode, and a Continuous Shooting mode after the click of a button. In a Continuous Shooting mode, the camera will stay on until your photo is taken. In a Manual mode, you can control the shutter speed and aperture. This is perhaps the best camera for outdoor landscapes.
Another good point and shoot camera for landscape photos would be one with an APS-C or Wide Angle Lens. Because this lens has a very shallow depth of field, it will provide you with an extremely shallow depth of field and very high-resolution image quality. This is because the lens has so close a view of the scene that the pixel filters can lock onto the area you want with pinpoint accuracy and allow the camera to take an excellent photo.
There are many other options available, but these are some of the best possible Pentax lenses for landscape photographers. Pentax has been making high-quality cameras for years now, and they are definitely on the cutting edge of photographic technology. The Pentax K-1 line is a great example of this. Be sure to do some research before purchasing any camera, to find the model and lens that are right for you. There are also many Pentax lenses available for purchase online.
