Completely agree. Lens choice is almost like the filmmakers' signature. Terrence Malick loves wides, from 14-28mm, which is pretty rare for non-comedic or non-fantasy films. If you like the compression of space that a 100+ mm lens gives you, then do so with a purpose - not just because it looks pretty; same for going super wide. It all comes down to making the right choices for the right reasons and remaining dedicated to that vision.

While I like my Canon glass, I regret not buying more manual lenses (like Rokinon). I hate being burdened to one company or else (as I currently do) have to adapt an electronic lens to another camera. Oh well, I guess I'll just get used to locking down on one aperture when shooting.
