I have an upcoming trip to GNP with the family. The primary purpose is the daily hiking adventures, but I plan to weigh myself down with my 6D and accompanying lenses. I've been to RMNF and Yellowstone. The wildlife encounters were fairly close at both locations. Only the grizz encounters at Yellowstone required more than 300mm to fill the lens.
I am looking for some insight as to how close the wildlife encounters will be in GNP and what would be the best lens to have as my primary mount? I have a 24-105 and 70-200f4. I was planning to rent a 100-400, if needed. Advice and insight is greatly appreciated. Thanks
