Canon L EF 135mm f/2L USM 135mm
The fast f/2 aperture combined with two ultra-low dispersion elements delivers sharp subject isolation and suppressed chromatic aberration, making it a classic portrait lens. Its ring-type USM autofocus is quick and reliable, while the relatively compact, lightweight build at 71g defies typical telephoto expectations. This lens is best for portrait and street photographers who prioritize a bright aperture and beautiful bokeh over modern features like image stabilization.
