I use my lenses according to the subject. The additional film used by the format permits capture of additonal detail where that is offered by the subject. Thus the 90mm can select an area of a close subject or isolate an area of interest from an expanse of landscape. That said, I use the 30mm > 45mm > 90mm.
I would rarely use any of them at full aperture.
