I absolutely love my Zeiss Loxia 21. I am still amazed by how sharp the images are given how small the lens is. I have been flirting with a lens better suited for astro like the Voigtlander 21 f/1.4 or Sony FE 20 f/1.8, but there are tradeoffs with these lenses relative to the Loxia.
Here are some images that I took last fall on a backpacking trip in Washington:
