One attribute of this lens that doesn't seem to get mentioned much, perhaps because it's not exactly fast, is how well it performs in low light - at least when attached to a FF body - when merely taking hand-held snapshots. A week ago I was wandering around NY with my 5DIII & 70-300L (I left everything else in the car) and ended up in Central Park as the light began to fade; and as it did, it began to snow. The light was magical and the camera/lens combination did a rather good job of capturing it. (They also did a rather good job of ignoring the snow - I had nothing to protect them with, not even an umbrella, so I just occasionally shook or blew the snow off as it accumulated and kept going until I decided to stop a couple of hours later.) No noise reduction despite the rather high ISOs (I think the grain enhances the look). The results could perhaps have been better with a faster lens or a tripod or someone better behind the camera, but none of those were available.... These four are in Central Park. In the next post I'll add three from a bit farther south.
