Seeking a lens with 400mm reach to use with my Canon 7D Mark II. I am open and flexible to brand, Canon..Sigma..Tamron..etc. Also open to it being fixed focal or zoom. Intended for wildlife photography. NOT for "bird in flight" type photography. I photograph mostly slower moving animals or animals that are still and mostly in a rain forest setting.
My criteria is that the lens be in excellent cosmetic and functioning condition as well as I DO NOT generally like to buy lenses that are more than 5 or 6 years old.
