What is the Canon 7-21mm?
The Canon 7-21mm is a versatile zoom lens designed for Canon DSLR cameras. With a focal length range of 7-21mm, it offers a wide-angle perspective that is perfect for landscape, architectural, and interior photography. This lens is part of Canon’s professional L-series, known for its exceptional build quality and image performance.
One of the standout features of the Canon 7-21mm is its constant aperture of f/2.8 throughout the zoom range.
