During my 30-year pro career I rely heavily on Canon's ultra-wide angle lenses from all three generations of the 16-35mm 2.8 and the fixed 14mm. This lens is far superior to all it's predecessors. Not only is it wider but seems sharper with less distortion.

Excellent quality. Great effects with this lens also.

Pro: Excellent outdoor and landscape pictures Con: 1. I can still see certain amount of distortion. Canon never said it is Zero distortion. Sigma version advertised as "no distortion" 2. Price is high. the lowest price (US warranty) I have seen is $2499. International version is $2200 3.

Expensive, but well worth it, great optical quality and heavy as hell especially with a 1 series body

Durable; Great Features; Great Picture Quality

Excellent quality lens - gives true "WYSIWYG"

"This lens is amazing. A true rectilinear wide angle zoom covering 11mm to 24mm on a full frame sensor. Not a lot of point on a crop sensor, there are less expensive options that provide the same coverage, but for full frame this lens is a killer. Know that it is big and heavy.

When it comes to choosing a wideangle lens, photographers using a Canon full-frame DSLR have one of the best ranges available. For those working to a strict budget there's the very respectable EF 17-40mm f/4 L USM, while for those who can justify the cost there's the superb EF 16-35mm f/4L IS USM,...

I have had this lens for about 6 weeks, takes a few uses to adjust the way you look at the world, incredible how close you can get to a subject. The lens is heavy, but anyone used to pro lenses should find that isn't a problem.

Sharp pictures, a whole new perspective with no distortion wide angle.

no distortion high quality construction

While it's a shame that picture and sound quality haven't been upgraded, the iPhone 13 was great in these regards and the iPhone 14 is, too Excellent display Admirable headphone performance Solid build quality No upgrades to picture or sound Familiar design Notch is still present
