I rented a tilt-shift lens this past weekend in preparation for an upcoming shoot (since I knew there'd be a bit of a learning curve). I couldn't get ahold of the wide angle version since wedding season is in full bloom and it was already rented out, so I went with the less popular older brother (TS-E 90mm). It's a tricky little thing to use, but opens up a ton of creative options as well. For me, it definitely allowed me to relive the feeling of picking up a camera for the first time as I found myself taking pictures of the most mundane things just to see how tilt/shift would affect the shot. One of these days I hope to add one to my regular lineup.
