In reply to mark s:
I've had a 5D3 for a few years and recently bought an XT2 and a few lenses for a trekking trip which didn't happen. Initial observations are: I will take the XT2 out in the hills and on my bike, and use it, far more often, which is key really. I can see myself backpacking for days with focal lengths 15mm to 210mm covered without a second thought whereas with the Canon I'd be very careful about which lenses to take because of weight, bulk and whether I could be bothered getting the thing out of the bag. I can also get away with a lighter tripod and head, which makes the difference between taking one or not.
That said, I love the Canon especially the viewfinder and the general feel. As said above though, the Fuji is a lovely tactile thing and brings back memories of my beloved old Nikon FM2.
