The Canon EF 17-40mm f/4L is a high performance, water-resistant wide-to-normal zoom lens that is perfectly suited to landscape and outdoor shooting. It produces little distortion, making it a good choice for architecture and interior photography as well. It is a versatile lens that can be paired with both full frame sensor cameras, such as the Canon 5D Mark III, and with crop frame sensor cameras, such as the Canon 7D Mark II. The focal length equivalent on crop frame sensors is 27-64mm, a great range for events. It accommodates 77mm front screw-on style filters and also sports a rear filter slot mount that can hold up to three gel filters. While this lens is lightweight and easy to handle, it does not have built-in image stabilization. If you need image stabilization in a similar range, please see the Canon EF 16-35mm f/4L IS USM Lens. This lens is ideal for events, vacations, landscape photography, real estate photography, vistas, and high quality candid shooting.
