Canon lover switched to RX-100, and it was terrible! Need advice....

After reading all of your posts, I still can't figure out what is your point?  Perhaps you should read up on digital sensors and imaging and understand the laws of physics a bit.  There are finite limits to what processors and lenses can achieve, and photography is a means to create images of beauty and power, not to waste time and energy on minute imperfections in the output while pixel peeping.

Why bother if your focus is on "noise" as opposed to focusing on creating quality images?
