One of Canon’s best portrait lenses, the EF 135mm f/2L is a surprisingly lightweight yet very fast telephoto. Its fast f/2 aperture combined with this len’s ability to compress space makes it an incredible portrait lens. Its fast glass is designed to provide very pleasing background blur with excellent subject isolation. Great for headshots and portraits under available light, the 135mm f/2 is a beloved lens by many Canon photographers. You can also combine this lens with Canon EF 1.4x II and 2x II teleconverters for even more reach.
