Metering
The LX has excellent low-light performance using dynamic, off-the-film-plane TTL metering called Integrated Direct Metering (IDM). Pre-release exposure information is obtained from light reflected from a patterned shutter curtain back to the sensor. This exposure metering makes the camera excellent for available light photography. TTL flash control is also available using Pentax dedicated units. Exposure control is manual or aperture priority automatic. Automatic exposure time is up to 125 seconds.
