I've been reading many of your informative posts over the last few weeks and would like your opinions... I will be visiting Yellowstone, Yosemite, Grand Teton and Grand Canyon this year for vacation/work. Lucky me, right? I really like the look and features of the G3 and would like your recommended must-have lens(es). Obvious subjects will be landscapes and critters at long range - if their teeth are large! I like the size of the G3 and MFT packages, but I'm still reading the Trey Ratcliff and Ken Rockwell blogs... both recommending Nikon D5100 or more for image quality. (Hope that's not taboo around here.) Your recommendations and experience will help me with a shopping list and real world comparison between G3 with lenses and D5100. Thanks for the help.
