<p>Agree with Gerry: if you can get higher resolution with no penalty, why not? If not for better looking big prints, then better cropping/adjustment ability. I have a GH3 now, and will likely sell it for the GX8 which is better suited to my needs. I do little, if any video. And the GX8, if it's a good as it looks, will make a killer walk-around when paired with the 14-140 and a nice light travel kit with the 7-14, 12-35, and 35-100. Very high quality glass that can take advantage of that new sensor.</p>
<p>As it is now, I've made 4' wide prints from the GH3, and they look really nice. Surprisingly good, actually. So I'll take a long look at the GX8. If the EVF is improved, that alone might be reason enough to upgrade.</p>
