180 is a very useful focal length for a 4x5 camera, and the lens probably has a large enough image circle to allow for considerable camera adjustments.

My 1st view camera was a Calument with a 180 Rodenstock Sironar, and I never felt that lens to be lacking in any way at all.

While 135 is a slightly wide view lens for 4x5, I have found no 135's with a large enough image circle to allow much camera adjustment, but they are nice compact lenses, and useful for landscape work where adjustments don't need to be extreme, usually.
