A Google search found this link, which discussed the equipment and film Kubrick used to shoot the candle-lit scenes in Barry Lyndon.

What they mention about focus is interesting 
One thing i remember was seeing people complaining about the Star Trek movies on Blu Ray being very soft (Specifically I-VI) when i was looking at the reviews for them, I bought them anyways figuring why not and when I watched them I saw exactly what people we're seeing, but my experience as a photographer quickly figured out what EXACTLY was happening, The scenes were being shot with fast lenses and the FOCUS was off, I could find small areas where things were -very- sharp but yes, the scene was "Soft" or rather, most of it was at the extremes of depth of field
it had nothing to do with the upconversion to blu ray, but how it was originally shot, They put the focus somewhere in the center of the frame, using what was obviously a fast lens which gave just enough depth of field for everything to be sharp enough, Anytime they did closeups of ONE actor or one specific object everything was sharp as a tack (because they focused to specifically isolate that one thing) but say, a group shot with multiple characters would be quite soft looking
its just that nowone could see this until it was put on Blu Ray....
