Ever find that you just can’t fit enough of your scene into the frame? Wide-angle lenses have a broader field-of-view so you can squeeze much more into your image. Having such a wide composition is ideal for many avenues of photography, including landscapes, architecture and street styles.
Anything wider than 50mm (full-frame equivalent) is classed as a wide-angle lens, because it’s wider than what the human eye can see. On a full-frame camera wide-angle lenses are usually around 15-30mm, while on APS-C cameras it’s more like 10-20mm.
