We finally expanded our lens collection to two. We just picked up a 17-40mm f/4 lens. This enables very wide angles, here are some test shots with it:
For this one, I was pretty much right next to Corrina, but because of the wide angle, it makes it look a lot further away.
You can also get a lot of a small space (ie. my condo) in the frame.
Of course, we'll still put the 50mm f/1.4 to good use as well. (We're watching the Cubs sweep the Brewers in the background)
