With the 85mm, you can still be close enough to interact but you've also got beautiful perspective.
"The EF 85mm f/1.4L IS USM is the traditional portrait lens and a particularly flattering focal length that I love. With the 85mm, you can still be close enough to interact but you've also got beautiful perspective. If you're photographing kids running around or cycling off on their bikes, it gives you that little bit of extra reach without losing conversational space, which is where you get interactions and expressions."
