Can I adapt the meike 85mm f 1 8 se mark ii to nikon z?
You don't need an adapter for this one. The Meike 85mm f/1.8 SE Mark II is listed for the Nikon Z mount, so it fits your camera directly.
On a full-frame Nikon Z body, such as the Nikon Z6 II or Nikon Z7 II, it frames as a true 85mm. On an APS-C body like the Nikon Z50, it acts like roughly 128mm on full frame, which is tighter than most people expect for portraits.
It's an autofocus lens with no image stabilisation, so pair it with a body that has stabilisation if you shoot handheld in dim light. For the full picture, see the portraits guide.
