Not only for still life, but for almost everything I reach first for my trusty 210. I have a 150 when I need to go wider, a 305 when I need to reach out and touch something, and a 90 for extreme situations. But my first instinct is always the 210, which I find very interesting since my overwhelming favorite medium format lens was a 150, for all intents and purposes the corollary lens in MF. My unscientific hypothesis is that everyone "sees" most naturally at a certain perspective.
