I agree, the T4 is a nice camera, and it is "weatherproof" for what that is worth. Nothing wrong with using point and shoots. Aside from what has been mentioned, there is also Moriyama Daido who uses the Ricoh GR1. And Robert Frank used a Rollei 35 for The Americans, as did Stephen Shore for American Surfaces, IIRC, although the Rollei does afford more control.
