That is a great shot. Photographic opportunities can come unexpectedly. If your lens had vibration reduction (VR), you would have nailed that shot perfectly in focus.
Lens has Image Stabilization feature (IS in Canon world, same as VR in Nikon world). I probably had it turned off though; with exposures 1/100 or above I was shooting all day IS is not needed & actually does some harm. This was so sudden & I just had time to point and shoot. At least I exposed for foreground which was much darker than horizon, but this is where he was. I'd have simply bumped ISO if there was more time.
Landscapes are easy to shoot. They sit still and wait all day
Wildlife is tough. This is why pros go to Africa on a safari with all kind of high-end gear & sit in jeeps all day. But when you backpack the Rockies it is almost entirely matter of luck. I am always amazed by quality of these grizzly bear shots lobo posts here. Like they wait for him.
