Hello!

I've just bought G1x and while testing chdk I've noticed the 1 second exposure time limitation (in all G series cameras...)

Is it posible to override this using chdk and get slower shutter times using AV mode?

Thanks

Thanks, I'm not sure what have I done, but it seems the camera now in AV mode can expose more than 1 second only if I set ISO-AUTO...

if I set iso to any value it limits 1 second minimum shutter speed...

It seems you are describing how the Canon firmware works in Av priority mode? This has nothing to do with CHDK behavior ? Is that correct?

No. With canon firmware av mode is limited to a maximum of 1 second. .. But if I boot with chdk i get lower speed values (if I set iso to auto)
