I normally try to shoot at the same focal length as my eyes, which is equivalent to about 50mm on an old film 35mm camera. Then get far enough away from the tree to see as much of the crown as possible; also eliminate camera tilt. Here's a stitched image of Del Norte Titan redwood. BYW, Zach Urness of the Salem Statesman Journal wrote this excellent piece about trampling in the Grove of the Titans, and efforts by the National Park Service to minimize it. I gave $100 to help pay for a boardwalk.
The article was okay, but the woman who did one shortly afterward in the Triplicate did a better job than Urness is not propagating certain things that will "spread sparks" so to speak.
RE photos like the DNT above, I find with my new Canon 5DS, that I can get big images from within images, lessening zoom or distortion sometimes. I may just fit what I want in the top of the shot to avoid tilt and just crop the bottom away. It's an interesting camera to use.
