Best 14mm Prime for D750

Hi I finally jump ship from Canon to Nikon, Im looking at a 14mm Prime for D750 and would love to have some advices.

So far, it seems that I only can choose either Sigma 14mm f/1.8 DG HSM Art or Samyang AF 14mm f/2.8 Lens.. No Af is very painful for me..

The Sigma is slightly heavy for me.. Can anyone recommend me a lighter or slightly cheaper 14mm alternatives?

Im only looking at prime, cheers..

14mm doesn't really need auto focus. Those two you mention are both very good lenses. The older Samyang is also excellent value for money - I use that on my D4 from time to time

I just purchased a samyang 14mm and while I was researching this focal length just about every review stated that you dont need af. Its so wide that you dont need to af it, everything is already in focus, absolutely no bokeh.
