Actually, I shot this with a Canon fixed 200mm f2.8. Its a brilliant lens, especially if you travel with a lot of gear because its really small, light weight and magnificently pin sharp. I only carry one zoom – the 16-35 f2.8. All my other lenses are fixed – fish eye 2.8, 50mm 1.2, 85mm 1.2, 200mm 2.8 and 400mm 5.6 (the exception to the rule, but a really small, sharp long lens). I like to shoot in a lot of extremely low light situations in which the zooms struggle a bit in my experience, even the 2.8′s. Also, there’s something about the simplicity of using a fixed lens that really inspires me. Its a personal thing but I’m pretty sure I take better photos when I’m confined to one particular focal length on a camera. It teaches you to make the most of what the lens can offer you without giving you the option to reframe unless you move on your feet. I like that. It keeps me focused on what I’m doing in a situation. Of course, I always travel with 2 bodies, so this gives me options. Most commonly, if I’m shooting people I’ll have the 50 and the 85 on the cameras – its a brilliant combination.

It seems you also used the 85mm f:1.2 for this shot. Just out of curiosity: what’s the zoom lens you normally use? The 16-35 f:2.8? 28-70 f:2.8? 17-40 f:4?
