I'm considering renting a tilt-shift (TS-E 24mm f/3.5L) lens for about a week when I travel abroad to do some photography in the middle east. What's the learning curve like on those lenses? Can I get anything accomplished if I'm completely new to tilt-shift and only have a week to use it?
What creative/interesting things can you do with them? I'm probably looking to do architectural and those fun miniature faking stuff if I do end up taking one.
My other option is renting a standard ultra-wide zoom (EF 16-35mm f/2.8) for landscape shots, so I'm trying to find the best artistic value for money.
I guess I should add that I'm not very skilled at manual focusing.
