Well, the Otus is a little bit bigger , isn't it ? And more than a stop slower.

As a rule of the thumbs you can double the size/weight per stop (when keeping the quality).

The results aren't that bad at max aperture IMHO (in relation to the aperture).

  sure, neither are light weights, however, I thought I was "understanding" with regard to the Zeiss pricing, here I'm more than struggling, but  hey, if money's no problem....

 

 thanks for the review mst,nice
