A lovely lens for the price, very fast to focus and very quiet. I use it on a 600D body so only use the centre area of the lens. I suffer no curving on the edges as full frame sensors are reputed to suffer. As you would expect for a "L" series lens, it's built like a tank with weather sealing.

Bought this lens to round out my lenses for Landscape photography. Took it on a recent trip to shoot waterfalls at a local state park, did a great job. Sharp, vibrant pics - very satisfied!

This is a great wide angle lens & in my eyes represents better value than the 16-35 for a few reasons:1- it's literally half the cost2- it's a lot lighter3- I don't have a need for f2.8 when shooting landscapes.I really like the images that it produces & the quality of the L glass speaks for itself.

I use this lens for shooting abandoned buildings, so I can more get the scope of the place I'm shooting. THe only thing to keep in mind is that this lens is an f4, so there are some speed and low light issues, but if you're using strobes then it's not a problem.

Strong Construction

Poor in Low Light

I love this lens. Nice color reproduction and fast focusing. Gave me great results in my last outdoor photo shoots!!

Consistent Output; Fast / accurate auto-focus; Nice Bokeh; Strong Construction

This lens is well worth the price and I hate paying high prices for things. I would give this lens a 9/10.

Great detail and color in photos really can't ask for more here; I am a novice in the full frame camera world but I have to say this lens does everything I ask of it

Slow focus time and sometimes the lens can't focus at all if what you are looking at lacks enough detail to get the right sharpness; Zoom is very small and basic but decent for close ups

Top quality wide angle lens, with great use for landscape photography.

Excellent lens, as expected for an L series lens, Very light

I used this lens on my 7D for about 5 years until my camera and lens were stolen. After a year of waiting and saving up, I finally made up my mind to buy this lens again. I've become very used to how the lens shoot over the years and that was the main reason that led me to purchase it again.
