This dude was killing it. Paris 2015. I utilized my sneakers to get this close shooting shallow on my 50mm. I find other lenses are a little heavy in a city like Paris where you walk and walk and walk. Discreet enough to snap quickly and quietly and keep walking too. Just remember to expose before you put the camera up to your eye.

Red sunglass case (I assume?) in his pocket is kind of perfect too.
