Today, I was pleasantly surprised when I found out my work purchased a new lens for testing. This time, quite an expensive one! When we pulled it out of the box, I couldn't help but notice how hefty it is! It really puts my 50mm 1.4 to shame in that regard. Build quality also seems very nice.

Looked at some reviews and it seems to perform admirably, but not much better (if that) than some of the other 50mm primes. The benefit, obviously, is the optional f1.2.

Has anyone had experience with this lens?

I may be taking it home sometime soon to check out
