We'd like to think of the Canon 35mm as the go-to prime lens for professionals.
Canon's EF 35mm 1/4 L-series lens boasts the brightness of the largest aperture in its class. The lens utilizes a floating system that allows for the highest image quality over the entire focus range. Rent this lens for the week and you'll understand why this is the go-to prime lens for professionals. The lens utilizes rear focusing for fast, quiet autofocusing and discerning users can choose to shoot in full-time manual mode as well.
