Re: "Envelope" is a more useful concept than "equivalence" IMHO

Aha! Detail Man at last! The OP asked if the LX7’s IQ competes with the Sony RX100’s. Unfortunately, rather than getting pictures of the same subjects from both cameras in order to compare directly, we have become bogged down in all sorts of theoretical ephemera an interesting facts.

If I can paraphrase him correctly, in ultimitsu’s universe, the RX100’s has a better IQ partly because its f1.8 lens is faster than the LX7’s f1.4 lens. In my universe, and that of a few other posters, an f1.4 lens is always faster than an f1.8 lens, but that does not enter into any argument about IQ.

Exactly, Cyril.  IQ might be about a big landscape in nice cross-light, with a tripod.  In terms of lens "speed", any camera would do.  These are conditions where we used to use 25 ISO film.

Edit:  Hey, that's end of thread.  Thanks!!!!!  In many other DPR Forums, this debate might have turned a lot nastier.
