Can I adapt the voigtl nder nokton 50mm f 1 2 aspherical to sony e?
Yes. The Voigtländer Nokton 50mm f/1.2 Aspherical is listed with a Sony E mount, so it fits Sony E bodies directly and you don't need an adapter. It's manual focus only, so you'll focus by eye, using your camera's focus peaking and magnification.
On full frame it frames as a standard 50mm. Good picks:
- Sony a7 III: a sensible full frame body for everyday shooting with this lens.
- Sony a7R V: the one to choose if you want the most resolution for detail.
- Sony a6700: an APS-C option. Here the lens frames like 75mm, and f/1.2 gives about the depth of field of f/1.8.
If you're new to lenses, the lenses page explains why a fast standard prime is worth having.
