This a a wonderful lens to use. Very little optical distortion and the photos have a clarity and color you can only get with these new second generation of Canon optics. You are way better off with the 24mm and 50mm L lenses than you are with the 24-70mm lens.

Can't buy a better lens at the 24mm length

Expensive; but worth it

I bought this for indoor ambient light shooting and it's a great lens for that.

Easily Interchangeable; Fast / accurate auto-focus; Nice Bokeh; Strong Construction

I mostly do portraits and event shooting with telephotos. But I bought this for the rare wide shots because I've always HATED my 24-70's soft focus! This prime lens is so sharp and consistent across the board I now choose to go wide 100% more of the time

"After being disappointed in the performance of the kit lenses bundled with my Canon 40D I decided to buy this lens (Canon EF 24mm F1.4L II USM). What a difference. This lens is very well suited for low-light interior photography as it's fast and has a nice and wide FOV.

Wow is this lens beautiful! Build quality is what you'd expect out of Canon's top of the line. It's rock solid. Feels great in the hand. Image quality is in my personal opinion unmatched for such a fast wide lens. It's most definitely a must have & must buy!

I like this lens very much. I will be using it for group shots and for landscapes. Focus is good, and low light capabilities are great. Lens is heavier than I would have thought but still within reason.

Beautiful lens, beautiful colors, contrast, saturation and details

It's an excellent lens, obviously, it's an L. My only problem with it was slow autofocus. However, I was using it indoors without flash, and am still new to the lens, so we'll see...
