What does shutter "Auto" mean ?

Hi all,

My EX3 is broken. First it was the focusing ring of the stock lens that I was not too worried about as I don't often use the stock lens. Then I got this message regarding slot A which is not being recognized.
Took it to the lab which qouted me 3000$ (no extra zero....)-: )

I can still use the camera but the shutter is stuck on either "off" or "Auto".
I know "off" is 1/25 sec when shooting 25p which is too slow for me but I have no idea what is the actual speed on "auto" - any idea anyone?

Thanks,

Ofer

Auto shutter means that the camera has control of the shutter as one of the variables for auto exposure, either because you have selected Full Auto or because auto shutter is selected in Menu>Camera Set>TLCS

As far as I can establish, TLCS in dim conditions opens the iris fully and increases gain to the AGC limit. As light levels increase, gain drops to 0dB, then the iris closes to the A. SHT Point. All this is with the shutter behaving as it does when the switch is set to Off. As light levels continue to increase, the camera increases shutter speed to the A. SHT Limit. AGC and Auto Shutter can be enabled or disabled independently.
