Customer Reviews

I love lense!
As an amateur photographer, this lens makes me look like a pro.

It quickly became my favorite, trumping the kit lens that came with my Canon 40D.

Bravo Canon!

My favorite lens
I'm new to SLR cameras, but so far this is my favorite lens. The pictures come out sharp and clean. More so than my zoom lens. I have used it for portrait distance, closeups, and even for landscape shots with good results. Very good in low light. It's an easy lens to carry around attached to the camera. I highly recommend this lens.
I had heard primes were better lenses and in my limited experience it seems true.

Incredible value, the extra stop makes a difference
The classic question about this lens versus the next one down, with a stop less and twice the cost, is whether or not its worth it. My opinion is that it is.

The very short depth of field at f/1.4 is incredibly dramatic. It's also a little tricky to use. There's a slight learning curve here to consistently get what you want in focus. I had to first set the camera to use just one of its focus points, and then use that, focus, and recompose. I'm still learning to look very carefully then at what I'm seeing in the viewfinder, and try not to move forward or back because what I wanted to have in focus will move out.

But with practice and subjects that aren't moving, getting that focus right on the reflection in an eye is priceless. I'm using a 5D, so I have the full 50mm view, but remember that with most of the DSLR's you're going to lose some of that with the field crop.
