I am a wedding photographer but I love taking pictures of landscapes. I do not have a lot of experience but want to do it as more of a hobby especially now that I ordered the 5DSr. I mostly have wedding and portrait orientated lenses. I am looking at getting the 17mm or 24mm tilt shift lenses. For those of you who shoot landscapes, would those be the lenses you get and if you could only have one which one? Right now I have lenses like the 24-70 and 70-200 which may not be the best.
