With so many critters coming to the feeding station outside our living room window, we keep a DSLR, with a zoom lens, on its tripod there, all the time. It’s great for quickly getting shots before something runs away.
However, with the lens on there, it also means we are almost never able to get our group of 3 deer visitors all together! At least not while they are close to the house.
Two out of three isn’t bad, though. 🙂
