Canon USM lenses of any length work more or less silently. But those with an EOS camera /might/ hear them in a quiet room. Working along a noisy river bank with an EOS body sans booster is very quiet. It's when you hang a Booster on that you get motor/winder "noise".
But then, we (photographers) too often equate the physicality of the shot itself (that visceral, very noticeable (to the shooter) viewfinder black-out) with whatever slight noise the shutter or mirror might make. To us, because of our immediate vicinity, the "noise" is noticeable. But hold a "modern" (post PZ1p) Pentax body cradled in your hands and shoot normally. Nearly any "noise" you hear will still be more the product of your /foreknowledge/ of the shutter's or mirror action than any shutter "shshst" or mirror slap the shooter senses more than hears. In a quiet place, like a conert hall, our body movement as we move our heads and shoulders with the (a) camera disturbs people more than any slight noise the modern shutter/mirror makes. The real trouble arises when you rewind. That high-pitched noise /is/ very noticeable. ===== I get it done with YAHOO! DSL!
