Traveling is what I do. I was all set to go ahead and upgrade (this May) from my crop travel kit (30D, backup 400D, 10-22, 17-55, 50 1.4, and 70-300) to a FF kit (5Dii, backup 7D, 17-40, 24-105, 50 1.4, perhaps a 70-200 F4 IS or a 100 F2) when I got to thinking about micro 4/3rds.
I am still leaning towards upgrading to the kit above, but I just checked weight. A GH-1, a GF-1, a 7-14, 14-140, and 20 F 1.7 are about 3800$ combined, weight about 3lbs and 11 ounces, and give me range from 14-140 plus one prime with shallow DOF.
The above kit without a telephoto zoom (just the 17-40, 24-105, and 50 1.4) would weigh 6lbs 11 ounces, and only reach from 17-165 (including FF + crop range). Upgrading while keeping the 50 and 70-300 would still cost me about 6,000$.
I completely get the great DOF with canon FF, the sensor size, the AF, the low light capability, but as a traveler also, the small size and light weight, and relative inexpensiveness of the system (plus I think I would irritate my GF more with less stops to change lenses or get it just right) makes it worth looking at.
Instead of trekking with the 17-40 on the 5Dii and the 24-105 on the 7D (or walking around with the 24-105 on the 5Dii), I would trek with the 7-14 on the GF-1 and the 14-140 on the GH-1. For walking around, I could have the 14-140 on the GH1 and the 20 on the GF-1.
Just thinking and thought I would throw it out there.
