What to buy and why: Consumer DSLRs

It is all about varying tradeoffs in Zoom, Price, Image quality, size, and various features.

RX100 is great not because of best image quality (RX1 or at least Ricoh BR would win) in a compact, but because it does so at a fairly reasonable price, with good supporting features like video quality, some zoom, good lens, all in a very compact body.

Some might prefer that Stylus 1 or whatever with its 300mm zoom range @2.8 aperture, despite its weaker overall image quality and less portability.
