It seems the lens is rather content. Its "L" moniker is well deserved because of the high quality and depth of the image it presents. It has a stubborn autofocus (it becomes problematic even at dusk, when it's nearly dark outside). Outdoors, it produces stunning images, but indoors, the camera's small aperture becomes apparent. It will work wonderfully with a fixed 50 f/1.4 street-indoor lens, I believe. I wouldn't wear it without a hood around his neck because he's obsessed with hares.
