Wow...I would love to buy every Otus that ever comes out, but I think the 55mm will be my last one. I always wanted a no-compromises awesome lens, and the Otus 55mm satisfies that dream.
The Otus 85mm would be a dream portrait lens, but I love the 55mm for that as well.
That's an amazing portrait david! yes you are right. the 55mm is just a shrine of lenses. but what zeiss does with us is this kind of a sickness. they make us WANT EVERY OTUS that comes out. and for me as a portrait photographer the 85 shines like the own ultimate portrait lens!
