From Luminous Landscape Review of the Panasonic GX7.
I believe that its now the case, that if you want higher MP's and sharper lenses, then you are actually better off renting Photoshop CC than buying a new camera or lens. Its probably a lot cheaper. As an example, until recently I had a Nikon D800E. Lots of MP's there and really excellent quality files. However with the new Photoshop I can upsize files from my Leica X Vario in particular to the same size as the D800E files and there is actually very little difference. Processing both identically, the Nikon files are still sharper, but adding a touch of smart sharpen to the upsized Leica file, makes seeing the difference very difficult, though the X Vario image will pick up some luminance noise when its enlarged. However in terms of printing and reproduction, virtually no-one could see the difference.
And then of course there's this. Ken Rockwell's latest little polemic.
