Like I said, I only used Cartier-Bresson as an example people might know. I'm not a HCB worshipper, he sometimes talked nonsense, especially regarding the colour work of Martin Parr, but he was largely responsible for setting out the ground rules for what we know of as street photography. One way not to criticise him, as I once overheard at a gallery, is people pulling apart his technique. They said an image showed camera shake or was poorly focused - who really cares when the composition is great?!
My whole point on this thread is technique, camera, lens, exposure, processing, is all at the service of an idea. When it becomes an end in itself, it's dead, you may as well run a surveillance camera. Ultra wides hold a white flag up to the idea, unless they're used with uncommon skill.
