Is the zeiss milvus 25mm f 1 4 good for landscape?
Yes, with a caveat. This is a manual-focus prime with no stabilisation, and that's fine for landscape. Landscape work is slow: the scene barely moves, and you can use a tripod, so focusing by hand and skipping image stabilisation cost you little. On full frame, 25mm gives a moderately wide view with a clean, sharp look.
The catch is that a single prime fixes your framing. You'll need to walk closer or further to change the composition, and you can't zoom. If you want one lens that covers the whole scene, a wide zoom is the better tool, as I say in my first-lenses guide.
If you're shooting landscapes on full frame, pair it with a body like the Nikon D810 or the Canon EOS 5DS R. Both are on this lens's list of compatible full-frame cameras.
