I was trying out "M" mode last night in my room. I switched off the room lights and the room was almost pitch dark. I then click the shutter release and noticed that I was not able to activate the shutter.
I then changed the lens setting from A to M. I was then able to activate the shutter.
Question:
1. Is the autofocus not able to work in no, or low light condition?
2. When I switch the main dial to bulb, under the M mode, I noticed that the shutter would remain open only when I press the shutter continuously, upon removing the pressure, the shutter would then close. Is there any method for keeping the shutter open, without the use of a remote control?
Thanks.
