What is Canon wide angle lenses? ↑
Canon wide angle lenses or other wide angle lenses are a lens which have focal length is smaller than normal lens. With small focal length, a wide angle lens allows more of the scene to be include in the photo. When you take photos for architectural, interior or landscape with long focal length the photograph isn’t look magnificent as a wide angle lens can do. And with wide angle lenses, photographer don’t need to move farther from the scene to take it.
Perspective: Wide angle lens help photographers to emphasis the size or distance of objects in the foreground and the background. The foreground objects (nearby objects) look very large and the background objects (farther objects) apprear small and far away.
Image circle: With wide angle lens you can get more of scene into photograph. But otherwise, it projects a substantially larger image circle, even a wide angle lens have the same focal length with a standard design lens.
Some best Canon wide angle lenses ↑
1. Ultra-wide Canon EF 11-24mm f/4L USM
This lens is one of the most widest angle than all the rest.
Although Canon have shorter focal lens EF 8-15mm f/4 but it’s just fisheye lens. With L-series construction and optics, the EF 11-24mm f/4L USM is one of the widest zoom lens that Canon ever made. It’s an expansive wide-angle with focal range 11-24mm. It anable to take interior shots, landscapes and unique perspectives on subjects close and far.
To minimize distortion from the center of image to the edge Canon designed EF 11-24mm f/4L USM with Four aspheric elements. Plus A Subwavelength Coating (SWC) and Air Sphere Coating (ASC) technologies enable reduce flare and ghosting affects. And the circular aperture with 9 blade creates beautiful, blerred background.

EF 17-40mm f/4L USM are assured by the use of three Aspherical lens elements and a Super UD (Ultra-low Dispersion) glass element. Optical coatings are optimized for use with digital cameras, but it’s also ideal for film SLRs.
This lens can focuses at minimum distance 11 inches (0.28m), a powerful ring-type USM for fast and silent AF, offers Canon’s full-time manual focus, which allows manual focus right after auto focus is complete, just by turning the focusing ring and without the need to switch to MF mode.

3. Ultra – Wide EF 16-35mm f/2.8L II USM.
One of the most importance Canon wide angle lenses in Canon’s lineup.
Same with other L-series Canon lenses in Canon’s lineup, the EF 16-35mm f/2.8L II USM is robust and features weather seals. It is a high performance, water-resistant.
It improved edge-to-edge image quality, one of the strict requirements of professional and high-end amateur photographers. It have 3 high-precision aspherical lens elements different style with each other: ground, replica and GMo. With this elements, EF 16-35mm f/2.8L II USM get better image quality than the previous model EF 16-35mm f/2.8L USM.
Its ring-type ultrasonic autofocus (USM) is fast and quiet, and new AF algorithms for fast and quiet autofocusing. Beside that, the circular aperture produces a beautiful, natural background blur when shooting at wider apertures (maximum f/2.8).
