On a long trip to remote areas of Tibet I carried a small tripod and two APSC bodies, three zooms that took me from 10 to 210 mm(equivalent to 15 to 315mm) and a bunch of little batteries. All in a messenger size bag. I have printed up to A2 no problems at all.
The FF is a little bulkier but still big weight savings overall. The problem is that I have to stop myself from taking three zooms and three primes and a flash and tripod simply because it’s all a bit lighter. For most stuff the body with the 24 to 70 is all I actually use or need.
Commercially it’s not a big deal as I tend to load up with gear and put it on a trolly.
