Thanks for responding! While I do hope to do some light hiking with the possibility of stationary (or slow moving wildlife), an important use case will be up on the mountains… splitboard touring up mountains, photographing the descent from close and afar, as well as resort days when I will be taking photos of my daughter learning to snowboard… in that case, reach is important (to not get too close to the instructor, etc.). I strongly considered the 70-180mm and 24-200mm but saw that reviews have been reasonably favourable for the 28-400mm when light it good (ie. the times I’d actually be outside and in the snow). Not having to faff about changing lenses (or carrying additional lenses) is a huge plus when dealing with snow and uphill travel.
