We caught this coastal brown bear walking through the lupines along a bear trail at Silver Salmon Creek Lodge in Alaska. Our guide and trip leader lead us to the end of that trail when they saw her enter that area. Was great timing as she slowly walked towards us, and we got out of her way.
The RF 100-500 worked very well on this trip with using it everywhere except the mudflats, where my 500F4 was the workhorse. It was much easier to lug around.
