Just back from a couple of weeks hiking in an area of Switzerland I’ve known for the last 30 years. It’s the only time I’ll travel light with photo gear, but still haul with both photo/clothing gear around 14-18kgs a day, as weather can change in an instant. However, having seen some of Andrew McLachlan's recent excellent work posted here on BPN, I did also pack the 8-15mm Fish eye for some fun, with the awesome Canon 1DX MK2.
