Hai Dave, "you are vote for the lens of the year?" Really?
And "So it's"? "fanfare music wells"?

Sorry to correct your flawless English ;-)

And I agree on that the Canon RF 50mm f1.2 L USM certainly is a contender... I only do not agree that it has magic bokeh. It has heavy cats eye, and yes, quite smooth bokeh in most distances, but a lens like the (way simpler) Nikkor AF 58mm f1.4 has even smoother bokeh.
Another contender could be the Nikkor 500mm f5.6 PF, for its low price and weight for a FF tele prime (and good performance of course).
Or the Sigma 135mm f1.8.

Oops on the "your"..........(hey did you look at the time when I wrote it?)

  Not sure what you're trying to say with the "fanfare music wells" though......"to well up"....
........swell.....increase in volume!

   Actually, in terms of lenses suitable for birders like me that would be the one.........my vote here was more about the importance of the brand related side of  lenses......breaking new ground....etc.
  .....as for bokeh and cat's eyes, how big does it have to be to not have them?

  .....You choose a Nikkor........
                  .....and I choose a Canon??

       This is a first........we'll be swapping gear next!
