I'm not sure whether this is the right place to post this however I am hoping that someone will be able to help me?
I purchased a Lumix G2 at the weekend, have been wanting one for ages. I really wanted the ability to change the shutter speed to get action shots, having only had a compact before this is all new to me. I played with the camera and when in the 'S' mode which is where I can adjust the shutter speed pictures tend to be very dark??? Even outside in the daylight! Is this normal for this camera? Can anyone tell me what I can do to rectify it if it is not normal???

Thanks
Catherine
