I have believed for a while now that the RX100 is the best camera if you are looking for diminutive proportions and best possible IQ. But let's suppose that the RX00 is "too big". What other cameras are worthy of the "Serious Compact" title that come in below the RX100 on the measuring stick? I'm OK with width or height being fractionally larger than RX100, but thickness is the driver for being "smaller" I think, and weight is important too. Some candidates: Canon S120 Fuji XF1 Fuji XQ1 Panasonic LF1 They all have smaller sensors than the RX100, which is a given I suppose, but do they still make the grade as serious cameras? What else should be on the list? Which is your favorite?
