Lensbaby.

My newest lens is a Lensbaby Composer. It has a sweet spot of focus that can be tilted to almost any angle, and depending upon the aperture, the picture is blurred from the sweet spot to the outer edge of the photo.

Adjusting to shooting with a completely manuel focus was a big challenge, but it also provided a certain level of creativity, which I love. At the beginning, I felt like I couldn't tell what was or was not in focus. Thankfully, the learning curve wasn't too steep, and I managed to get a couple cool shots.
