I think I like your first picture of the Mendenhall glacier best. It’s a better presentation of the subject and gives more depth. I do like the texture and colors of the second, but it’s too flat due to compression, given the focal length. I’d like it better if there were something in the second picture to give me a sense of scale.

What prompted me to respond here is that I was there on August 13 with the same two lenses but different full frame body. It was interesting to compare your images to my own.
