Thanks, Doylem, Evangelion and Rich! I went out to a new place yesterday, taking advantage of our unusually warm weather, thinking I'd use both my new lenses. That new 24-70mm just wanted to stay right on the camera and I had a lot of fun seeing how closely it focuses. In many of the shots I took, I deliberately used f/2.8 to isolate my main subject and deliberately underexposed a little. The colorful backgrounds I was able to get surprised me, considering that this IS winter!
Rich: sorry, can't send you a high-rez version for a background because I may want to do something else with this image once I see how well it prints up....
Here's another one, again shot at f/2.8 and very close up for a shallow DOF. This one could've benefitted from stopping down a bit, though! I just like the colorful background.....
