So, Paulo, what is your typical kit now and its weight, vs your similar focal length kit with the 6D and its weight?
The last kit I had with Canon included a couple of 6D cameras, plus several lenses: Zeiss Distagon 21, EF 16-35 f4, EF 70-300L, 100 macro IS, 50 f1.4.
Since early 2015 I pruned my shooting to travel, landscapes, people. Today I have the A7, A7II, Tokina Firin 20 (fantastic lens with f2 aperture), ZA 55 f1.8, FE 85 f1.8 (no need for the Batis once this gem came out), and I will complement this with the G 90 Macro and be done with it.
One year ago I climbed Pico mountain, in the Azores (the highest mountain in Portugal), with an overnight camping stay. I carried the two cameras with two primes in a small Lowepro backpack, plus all the camping gear, food, mini tripod, etc. A lot less weight and size.
