I believe that the LX is one of the best ever low light cameras, the pity is of course that it doesn't have a pixel array. The LX seems to get the exposure pretty much in the ball park during long exposures as other have indicated. Reciprocity failure can be a pain to manage and should be more so if you are using auto exposure with off the film metering as in the LX. The subject colour, the scene illuminants and the surface colour of the film all effect exposure times, however after much testing over many years I simply learned to trust the camera and bracket when it all looked too hard, I made a lot of great exposures that way. :-) I think that without special equipment (cryo-cooling systems etc) sensor noise tends to start to swamp the wanted signal in digital sensors, film is still much better at longer exposures, it has pretty low self noise :-) Cheers, Rob Studdert HURSTVILLE AUSTRALIA Tel +61-2-9554-4110 UTC(GMT) +10 Hours [EMAIL PROTECTED] http://members.ozemail.com.au/~distudio/publications/ Pentax user since 1986, PDMLer since 1998
