Ian - nothing's silent, but Canon get there by damping shutter noise on actuation and separating actuation from re-cocking. There's an interesting comment in the Canon white paper:
http://www.robgalbraith.com/public_f...hite_Paper.pdf
"A new and useful silent single shooting mode has been added to the regular complement
of single shooting, high-speed continuous (10 fps), low-speed continuous (3 fps), 10-sec.
self-timer and 2-sec. self-timer. During normal shooting, a magnet is used to release the
tension and the reflex mirror's downward motion is spring-driven. In the silent single
shooting mode, Pulse Width Modulation (PWM) control is employed to lower the effective
voltage. The motor's rpm is lowered and the reflex mirror is slowly put back down. PWM
control is also applied to the shutter-cocking motor to make it silent. The operation noise
of the mirror going back down is approx. 77 dB for normal single shooting. In the silent
single shooting mode, it is much quieter at approx. 70 dB. After shooting in the silent
single shooting mode and SW2-OFF occurs, the shutter will be cocked. You can thereby
control the timing of the operation noise."
I've heard it. It works pretty well. I want "silent mode" - I don't want to have to buy the 1D3!!
