Time will tell. I don't know which Otus is next. If it is 24 mm and F/1.4, it won't be as good as the existing Oti. Or if it is as good, it won't be as cheap.
It is worth every cent, I am browsing trough russian forum link which is full of otus samples. And based on this (from the same forum)
link Nikon has advantage over sony in details, but sony has little bit better colours. And somehow on sony it has more abberations. But It really provides full quality for 36mp, and more that will come.
It is nice to search internet with different languages, google makes short selection based on cookies and data they steal from you. If you search in japanese, sweden, german and australian more results will follow.
