In page 18, it specifically states that the LX provides stepless shutter speeds from 1/2000 down to 125 seconds. The 125 seconds is probably based on the meter's sensitivity to EV -6.5 at ASA 100 with an f1.2 because we know that the LX will hold it's shutter open for as long as the battery lasts or it accumulates sufficient exposure - whichever comes first.
This is interesting to me. When the meter is "summing" up the exposure, how does it handle reciprocity failure? The reason I ask is that on one of the LX's that I had shipped to me, I put the camera in auto at the end of the day in and took a shot of my bedroom...still end of day light coming from the outside but basically pretty dark. The camera held the shutter open for about 8 seconds or so and when I developed the film the shot was very underexposed. I thought that it was reciprocity failure and wondered just what "off the film" metering really means. Does this mean that with different films that have different tendencies that the meter, since metering off the film will AUTOMATICALLY handle reciprocity failure?
