I pre-ordered the LX100, because it looked so sweet. Since ordering that, though, I decided to (finally!) try a GX7 -- having pondered a purchase since March of this year. Well, after a week with the GX7, and after viewing the DPR LX100 samples http://www.dpreview.com/galleries/reviewsamples/albums/panasonic-lumix-dmc-lx100-samples-gallery I'm going to keep the GX7 and cancel the LX100 pre-order. It's not just the (possible) image quality, but also I really like telephoto. The P20/1.7 gets most of my 'normal' needs, and I have legacy glass for portraits. The GX7 is just such a joy to use. At first, it felt like a jet airplane -- the LCD was loaded with info, and there were tabs and Q menus, etc. etc. Overly complex. Kind of like when I first started using Oly in 2009. Took me a while to whittle it down to it's essentials, but having cleaned it up (turned off soft-tabs on screen, dropped the info-ladened LCD display, etc.) and it's really a nice, simple shooter that is ergonomic, responsive and has great IQ and I can slap a light-weight 40-150 or big-gun 100-300 on the front, or just roll with the P20. Also, it has a bounce-able pop-up flash The GX7 has won me over. Hope it lasts me at least 3 years. I just gotta stay off the lens GAS.
