Amazing piece of glass, sharp and light. I have canon 24-70mm and it's defiantly a great replacement.

This lens is absolute gold! I use it every single day for vlogging, filming, and photo shoots! The auto focus is amazing and the clarity is unmatched! I highly recommend this lens! I took it to Honduras for 2 weeks and didn't end up using any other lens.

Fast. Sharp. Essential to the prime lens collection. If you're wanting a wide angle, fast prime lens...this is the one you want. It's a Canon L-Series, so you can't go wrong.

This here is the BEST 24mm you will find in the world. Having a maximum aperture of 1.4 is VERY useful in low light and great for subject isolation. My only problem is that it had a bit of a front focus problem but I sent that to Canon for recalibration free of charge.

Durable; Fast / accurate auto-focus; Nice Bokeh; Strong Construction

Heavy

Chose this over a 24-70 f/2.8, for weddings and most everything else. Previously have extensively used a 24-105 f/4 (5D series kit lens) and 24-70 f/2.8, and I currently also have a 24mm tilt-shift. I shoot with a 5D Mark IV (full frame).

A superb lens for low light shooting but also an excellent prime for landscapes on full frame cameras. Optical quality remains excellent on a 1.6 crop camera and still provides a very useful focal length (close to 35mm). Great sharpness even wide open, fast and accurate focus.

Not cheap

I have held off writing a review on this lens for almost a year. I really wanted to see how it performed on a range of shoots in a variety of lighting conditions. With images taken on a Canon 50D and EOS 1D mk IV. My conclusion is this is truly a wonderful lens.

You have to like things wide to want this lens (I can easily shoot wider). Great for doco style, low light, action etc. Great bokeh from a wide angle. A good upgrade from the f/2.8 version. Only drawback is the extra weight and size.

If I had just 1 lens to use for everything this would be it. Its view matches how I see the world (on my 7D). It is fast, sharp, rock solid and reliable. Highly recommended.

Superior build quality; Super-sharp images; Fast auto-focus

It is great price and its small and light so can easily fit in my camera case for portability.

Its a good lens; fast focus with 50mm; inexpensive and produces sharp pictures

Feels a bit plastic and cheap
