It took me a couple weeks to get around to it, but I just finished "de-beeping" my AF35ML using petronious' instructions. It's certainly a very quick and easy mod, just a couple minutes with a small screwdriver and an X-Acto knife. And someone with a mind to could easily re-solder the wire later.
I do most of my shooting with this camera in lower light, since it goes up to 1600 ISO. Silence is definitely an improvement. 🙂 My camera's flash won't fire anyway (just whines and clicks, probably a bad capacitor) so the low-light beep was not only very annoying but also completely useless.
Incidentally, the audible battery check function on my camera still works even without the beeper wired in. It now makes a rapid clicking noise that's still easy to hear. The self-timer, however, now makes no sound at all. I never use the timer and I could just count to 10 if I did, so that doesn't much matter to me.
