I've been seriously considering that exact same combination of camera and lens, it will be very interesting to hear about your experiences with them. Another zoom that would be worth considering, though far more expensive, is the relatively new Nikon 16-80mm f/2.8-4E. They say it has the best VR Nikon has ever put on zoom lens. Enjoy your new toys! :-)

As for the Panasonic 12-60 zoom, I've heard very good things about it, and it might be very well worth keeping, especially for trip & travel purposes. Keep in mind that Panasonic's new faux-DSLR, the G85, which seems to be aimed squarely at the Olympus E-M5 Mk II, is priced at $900 for the body-only, or just $1,000 with the kit 12-60 zoom. The G85, as well as the GX85, has a newly designed electromagnetic shutter that has all but completely wiped-out the shutter shock issue. Hence, the special deal on the GX8, especially with the free 12-60 zoom tossed in, might just be Panasonic's way to keep that camera body selling. Other than the fact that the G85 has the older 16mp sensor in it, it is probably one of the very best micro43 cameras that Panasonic has made to date, with lots of nifty upgrades and a magnesium alloy weather/dust sealed body. Just a shame they didn't put the 20mp sensor inside.
