The Canon 50mm f1.2 is almost $2000 more expensive than the Nikkor 50mm f1.8. Would you seriously consider buying a €2500 50mm lens? I think Nikon was smart to bring a high quality f1.8 prime.

All depends on what I am going to do with it, if I will make prints I would sell or I am in professional business and need gear to impress potential clients, absolutely !!!
Otherwise (such is my case) no

Reminds me of this picture - they were probably laughing at the puny 50/1.8 lens I was using.

(the shot was indeed taken with a 50/1.8 lens on a Canon 1D Mark II N camera )

Not sure if they had fr a second thought about photography gear.....
Back to our subject, obviously such a lens doesn't offer much interest  for a photojournalist...it's just like having a huge SUV in crowded city
