In June, I'll be flying out to San Francisco with my dad for a few days, where we will then be driving down the coast to Los Angeles, where I'll be spending two weeks with my uncle. Obviously I'll have so many photographic opportunities thrown at me while I'm on this trip, but I'll be needing to rent a wide angle lens as I only have a 50mm f/1.4 and a 70-200mm f/2.8L in my kit. Also, I am shooting with a Canon T2i. I've been looking at different lenses, ranging from the 14mm f/2.8L to the 24mm f/1.4L, but the other day I remembered that tilt shift lenses are also a possible option. Specifically, I've been looking into the 17mm f/4L TS-E. I've always wanted to try a tilt-shift lens, which is why I feel that this could be a great option. I won't be using it for the cliché "miniature" look, but I feel that I could get some really interesting landscapes/portraiture.
Basically, my question is should I rent the 17mm for this trip? Do you think it'd be a good option? Is the learning curve large, or could I easily adapt to it? I'd appreciate any input.
Thanks in advance.
