Isn't in photography the king (at least in part) the one that's faster than the rest? And if it's also sharp wide open? And if it's small? And if no other 40 of any brand offers its speed?
After happily using it for one year wide open and stopped-down, it's "my" king... A marvel... Yet I don't know why it isn't more expensive... For softer bokeh when there are light sources in the background and it's focused close, I use it at f/2... But even at f/1.4 and in those hardest conditions, I don't find its bokeh disturbing: just modern... Sometimes I prefer it at f/1.4...
Cheers,
Juan
