As the title says, what is your favorite lens?
The answer doesn't have to be a lens you own or a lens branded Canon. But it will be better if you can share your opinion on why you like it.
To make a start. My all time favorite is the Canon 16-35/2.8L II. It's a high quality lens both in terms of its construction and the pictures it produces. It's a lens wide enough to contain the world around me and yet i can filter it with ease. There are just so many things you can do with it, and it is the lens on my camera most of the time.
Let me know what you've got.[]
