I used f/4 almost the entire day, concentrating on a single subject and ended up with mostly portraits and not so much environmental/streets. No surprises there.
It felt very different from using solely the 35'Cron the last time. Shooting streets, it was very nice to be able to hang back and frame to get the shot with less worries about being noticed. Kind of felt like a sniper ;-)
Here are some samples, the rest can be found in the personal gallery [HERE].
