100 mm Lenses
The focal length of a Canon 100mm is perfect for portraits, enabling flattering close-ups without distorting facial features. Available as a Canon 100mm macro, you can get exceptionally close to your subject with these prime lenses, without having to step forward, using the wide apertures to create stunning background blur.
