Guide for Beginners: Understanding DSLR Lenses
Another important lens that photographers need to focus on in their endeavour of understanding DSLR lenses is the wide angle lenses. This type of lenses has shorter focal length which is 28mm or less. It is very suitable for documentary type of photography or if you want to capture landscapes. However, it is important to know that wide angle lenses, when set at its widest, may result to a distortion at the edges of the image. Therefore, you might want to pay extra attention to your framing perspective while using wide angle lenses i.e. your main subject should always be somewhere in the middle, far from the edges.
Another famous lens is telephoto lens. The focal length in telephoto lenses is usually around 100mm to 300mm. It is suitable to be used in sports events, while taking scenery of wildlife or for portrait photography sessions. Images taken by this type of lens will usually have a blurry foreground and background. Due to the blurriness, images taken by telephoto lenses usually appear somewhat flat as they don’t clearly show the 3-dimensional perspective. Although this seems like a disadvantage, this is actually a good feature if you want to have a sharp and focused subject. For photographers who want to have a clear image without having to get too close to the subject, telephoto lens is also the way to go.
