Excerpt: I consider myself an avid photographer. I currently own a Canon Xti + Tamron 17mm-50mm f/2.8 lens. I also own a Canon PowerShot s95. I am extremely happy with both cameras. Because my wife and I recently had our first born child, I started searching for a low light camera + lens combo that is capable of autofocusing during video, which the s95 cannot. My search brought me to the 70D + EF 24mm f/1.4 II USM lens combo.
Great lens as its price says. The only issue to consider is whether you can afford it and use it well.

Summary: This lens allows you shoot architecture, landscape and portrait, but has large restrictions if you want to do other categories of photography like street snapshots. The angle of the lens is so wide that you might not see 100% of the scene through the viewfinder. Instead I would recommend sigma 35mm f/1.4, which has lower price than 35L but has better performance. Also, 35mm is more commonly used than 24mm. 24-70 will be another good option.
Excerpt: I have been eyeing this lens for a long time and I am glad I finally made the purchase. I realize some people have complained about focusing issues, however I have not experienced this problem. The lens focuses fast, very sharp and haven't had any problems in the first 10+ days of shooting. I purchased this lens for low light indoor shooting as well as landscapes including long exposures. The build quality is excellent and is very well balanced on my 6D body.
Pros: Consistent Output, Durable, Fast / accurate auto-focus, Strong Construction
Excerpt: I bought the lens for its build quality. I hope to use this lens as a "stuck on" for my 1D X. It is actually one of the very few Canon lenses that are small and weather-sealed (14L, 24L, and 50L). I like the 24mm focal length because it is wide enough to cover generally what you see. However, subjects don't get strong perspective distortion off center.
Excerpt: I use this lens regularly for photojournalism and landscape shots. Love: corner to corner sharpness, particularly in the 2.8-6.3 range. Good build quality, overall excellent performance. Don't care for the weight (though worth it anyways); lens becomes increasingly soft below 2.2.
Pros: Consistent Output, Fast / accurate auto-focus, Strong Construction
Excerpt: It is a little soft at 1.4 but was expected from such wide angle lens. I just shot one wedding with this lens and it performed well. The color and contrast is great. Also the build is superb. Overall great lens.
Pros: Consistent Output, Durable, Easily Interchangeable, Fast / accurate auto-focus, Lightweight, Nice Bokeh, Rugged, Strong Construction
Summary: The image quality of this lens is about the best I've seen at f/1.4 in any focal length lens. The clarity and colors are stunning, resolution is outstanding. I used it to shoot some video on the 5D Mark III in very low light (a small bar on New Year's Eve with funky mixed lighting) at around f/1.8 with ISO in the 3200 - 5000 range, and the footage came out so clean with just brilliant colors and an amazing film-like look.
Excerpt: If you do thorough research, you know what you're getting when you buy this lens. Like any professional tool, it has its strong and weak points. Aside from getting a faulty lens from the factory, anyone disappointed with this lens because it doesn't do what they need, should have bought a lens that does.As for performance: I use this primarily for astrophotography timelapse and it knocks the socks off anything else I've ever used.
