"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

Consistent Output; Durable; Easily Interchangeable; Fast / accurate auto-focus; Rugged; Strong Construction

Heavy

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...

Nice Bokeh; Rugged; Strong Construction

Blurry Focus; Heavy; Slow Focus

This particular lens was "off" dramatically in terms of focus accuracy. This was particularly disappointing because it was to go on a European trip with me (it got sent back instead). I have several other L lenses and will consider this an anomaly unless the next one is the same.

Strong Construction; Durable

Blurry Focus

Fast, blur background, can take in low light

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

I bought this lens second hand, 2 years old but in excellent condition. I found the focusing to work correctly the majority if the time. I mean majority of the time when you go in and pixel peep at 100%. Large aperture f1.4 lenses will not have 100% accuracy in real life shooting.
