This super-wide-angle lens is surprisingly sharp, even at the edges wide open

The 24-105 is excellent in the center and passable in the corners, but if you want a stellar wide angle shot across the whole frame into the corners this lens hits a home run

It is by far, the best wide angle lens that I have ever owned

Love how crisp it is and the wide angle

First, portrait photography is my specialty so a wide angle would be a rarely used luxury, and Second, the cost of that luxury has been prohibitive until now.

Spot on sharp and a fantastic wide angle lens.

Astonishing versatility in any situation where you need a great wide angle

Amazing super sharp wide angle

Bought this to do family and large group shots has a nice wide angle that will be ideal for the type of pictures I want to capture.

even if I wanted to -- I am not much of a technical wizard) but I will just reiterate that this lens would make an outstanding wide angle addition to your lens arsenal.

Excellent lens, very sharp, easily my favorite wide angle Canon zoom

Canon deserves kudos for producing a truly sharp extreme wide angle zoom at a reasonable price

This is the most sharp wide angle lens I have ever had my hands on

f/4 L lens I purchased from Amazon and it works very well, but I like the idea of an image stabilized wide angle since I would like to more video work and this lens (16-35 is) looked very promising.

Excellent, sharp wide angle zoom

A nice wide angle lens which could be faster.

What I loved about this lens was the light weight at 1.3 pounds (615g) for easy use in travel and hiking

For the price it's probably the best L-series quality lens you can buy.
