Been trying to shoot some shots at my kickboxing gym for our new website using my G£. They are all turning out very dark in S mode. So I swithed to M and the same, even with a high ISO. I then used the scene mode (sport) and this was much better but the shutter speed wasn't fast enough as 90 % of them were blurred. Am I doing something wrong, or is the standard 14 - 42mm kit lens not suitable????
