The Canon EF 24mm f/1.4L II USM Wide Angle Lens - Fixed has become my best night photography lens.
Check out my Instagram account for some of my night shots. This lens is the fastest piece of glass that I own. Now 24mm is almost to wide in some scenes. I get around this by attaching it to my cropped frame camera if I absolutely need a little more reach. With a 1.7x crop factor it brings the lens to a 40.8mm. Wait just a minute. This 24mm lens virtually replaces the need for a nifty-fifty if you have a cropped sensor. I also love this lens for shooting in close spaces.
Say you're at a client's home, and they want some images in front of the fireplace. This lens is perfect for that situation. I can shoot wide enough to get the family without having to melt into a wall to get a wide enough angle.
I have been shooting with this lens for over a year now. Let's see what I think the pros and cons are on this glass.
Extremely fast glass
It takes the place of two lenses in my bag
Super wide or nifty-fifty depending on what camera you use it on.
That creamy bokeh!
It is sharp from about f/2.8 and up
The price is pretty high considering
That is the only con I can come up with for this investment. If the price was below $1,000 I would have no complaints with this lens.
