Understanding Focal Length
Get to grips with the impact different lens' focal lengths will have on your photographs
Choosing what lens you decide to shoot with not only alters the appearance of the subject but also has a huge effect on objects that may be on show in the foreground and the background.
Lenses come in a huge variety of focal length from ultra wide to telephoto. Wide angle lenses are perfect for landscape and documentary photography. Or if you want to create images with a wacky and creative feel to them. While telephoto lenses are ideal for sports and wildlife photography. Or when you just want to zoom into an area within a scene and isolate it. Lenses that fall within these two brackets generally give a more “what you see is what you get” appearance. With a 50mm lens being the standard lens for a full frame DSLR.

28mm
An example of how the 28mm wide angle is ideal for a landscape scene. By shooting at this focal length there are many points of interest in this wide scene. The lighthouse, the beach and plenty of sky all dominate this image. Making the background appear visually pushed almost out of sight.
