When Carl Zeiss publicly claimed that an Asian company stole their design, stop what you're doing and buy whenever you can - unless money is an issue for you. :) This lens is extremely difficult to use unless you have a split focus screen, at f1.2 or f1.4 even an extra subject isn't that forgiving. But when you get it right, it's hugely rewarding - the quality, even wide open, is absolutely exceptional, not to mention the extra training you get from just wearing it with a full-frame camera body :) Enjoy.
