There were a string of amazing sunsets occuring while I was evaluating this lens. And telephoto lenses need only marginally nice sunsets to create great pictures due to their narrower angle of view. Not as much sky needs to be in blazing color to fill the frame.
In this image, I tried to balance the brighter sky with the spruce silhouette.
