Ultra Wide Angle Lens
Simply put, landscape photography cannot be done without the ultra wide angle (UWA) lens. So if there is just one lens that you can isolate for landscape photography, UWA is the one. But what makes this lens so idyllic for shooting landscapes? Actually, these lenses offer a greater field view along with the necessary depth of field. There are two types of UWA lenses:
The prime UWA lenses are mostly cheaper and produce high quality image. They allow the photographer to shoot at wide apertures, for instance f/2.8. This is particularly helpful when you are capturing the stars. However, a major disadvantage of the prime lens is that the focal length is restrictive and you will have to change your position if you want to “zoom” the image.
On the contrary, the zoom lens gives you the liberty of adjusting to a variety of different focal lengths. Seascapes are best captured with zoom lenses. The main reason is that you might not be able to adjust the lens with the help of feet movement.
The field view of the UWA prevents you from combining panoramic images. The horizon, with the help of UWA, appears further than it usually is, which makes the landscape photograph appear wider.
