The Fuji seem to be the best mirrorless cameras at the moment, but unfortunately the lenses are quite expensive. I don't like to travel with such expensive equipment since loosing or breaking a camera happens so easily..

This were some of the cameras and lenses (travel zoom + wide angle + prime) I was considering (Cheapest prices for new products in Germany in August 2017):

Nikon D5500 Kit 18-140 f3.5-5.6 (465g+490g/970€-50€ Cashback) + Nikon 10-20 f4.5-5.6 (230g/350€) + Nikon 35mm/1.8 (200g/190€) = 1.385g/1.460€. Possibly Sigma Art 18-35.
I love the handling, the amount of lenses available and even got it even a lot cheaper in the end..

Olympus E-M10 Mark II kit Olympus 14-150mm f4.0-5.6 (342g+285g/850€ - 75€ Cashback) + Olympus 9-18 f4-5.6 (155g/530€-100€ Cashback) + Pansonic 25 mm f1.7 (125g/170€) = 907g/1.375€
Con: Mft Sensor

Panasonic GX8 + kit Pansonic 14-140 (435g+265g/1.200€) + Olympus 9-18 f4-5.6 (155g/530€-100€ Cashback) + Pansonic 25 mm f1.7 (125g/170€) = 980g/1.800€
Con: Mft Sensor

Canon Eos M5 mit Kit 18-150 f3.5-6.3 (427g+300g/1.300€-120€ Cashback) + 11-22mm f/4-5.6 (220g/330€-60€ Cashback) + Canon 22mm f2 (105g/215€-25€ Cashback) = 1.052g/1.640€
Con: Almost no native lenses, Canon Sensor

Sony A-6000 450€ + 18-105 f4 500€ + Samyang 12mm f2 255€ 1.205€/976g + Sony 35mm f/1,8 400€/155g = (344 g + 427 g + 200 g)
Con: Great specs, but I absolutely didn't like the handling even though I came from a Sony camera! Also 105mm is not a lot of zoom and the wide angle zoom is very expensive..

Fuji X-T20 900€ + 18-135 700€ + Samyang 12mm f2 340€ (383g+490g+200g) 1.940€/1.073g = ( 383g + 490g + 410g)
Con: Too expensive for a travel camera
