I spend crazy amount of $ on super fast 5*mm lenses as collection purpose... but I have to say unless there is any unmatchable characteristic to this lens, I\'m not sure I\'m ready to drop 4k on it.
If you will own a 2014 56MP D5 or 65MP 1DMk.V and make a living off of it, a 50/1.4 G, 50/1.2 L or 50 MP likely won\'t do.
