another vote for the Sigma - I'll be replacing my Nikon with one later in the year
I'd get the Sigma (OTUS!) Art 50 1.4
The Otus is a Zeiss. It's also a 55mm and £4k.

I have just read an article about how Sigma has to reverse engineer it's AF software, and it struggles to match the brand camera lenses in this respect. Sharp is good, but focus is better! I would be more tempted by staying Nikon myself, given that I enjoy portraits the most.
