Zeiss milvus 50mm f 1 4 vs zeiss otus 55mm f 1 4?
Both are manual-focus f/1.4 primes for full frame, and both mount on Canon EF and Nikon F. The difference is focal length. The Zeiss Milvus 50mm f/1.4 gives you the natural, slightly tight view that 50mm is known for. The Zeiss Otus 55mm f/1.4 frames a little tighter, which suits portraits a bit better.
My pick depends on your camera:
- Full frame, general use: the Milvus 50mm. It's the more familiar view.
- Full frame, portraits: the Otus 55mm, for slightly more reach.
- APS-C: either works, but the 50mm is the cheaper way to get that 75-80mm portrait look.
If you're still deciding on your first prime, read the portraits guide or the first lenses guide.
