I own an x10 and love it to bits, but I see that there is a limit to getting creamy bokeh with it. I was toying with the thought of getting a Lumix lx7 which has f/1.4 aperture, but with the release of the x20,I'm tempted to get that instead. Based on the specs of the two, does anyone here have an idea whether the x20 is likely to produce creamier bokeh than the x10? Any camera options that you could recommend that would best the x10 in terms of producing shallow dof? Thanks!
