On the last trip the 6D stayed at home and was replaced by the two Fujinon zoom. Apart from the fact that this equipment can be transported easily, one has by the APS-C crop factor now even a quasi 300mm telephoto at the upper end.
I will not go into a comparison between full-frame and APS-C here. The photos can be in any case nothing to be desired.
At a regularly scheduled live musical event I was able to compare directly with the results of the Canon 6D and 1.5 kg EF 70-200 f / 2.8 zoom the XF55-200 at the X-E2. It is very difficult to admit it; but a difference which is to justify the price difference of about 1,700 Euro is very difficult to find.
From my perspective: Highly recommended!
