RX1 - Samples and Reviews (Part II)

Whether it makes sense or not depends entirely as to what you are shooting. For most forms of street photography the smaller sensor delivers benefits that make sense for a street shooter.

But... if max resolution, sharpness, dynamic range, lowest noise at any given sensitivity especially higher up the dial, more control over depth of field, smaller apertures before diffraction limitation sets in -- if all these things are of use to a photographer than a larger sensor will continue to have an edge over smaller sensors. In some of these areas the gap may narrow yet in others sensor improvements won't overcome physics.

What will probably happen faster than performance improvements narrowing the ability gap is production improvements will narrow the price gap.
