Bernard,
...I am pleased to read that the first reports are positive!
Indeed.
It will be interesting to see how many lenses, and in what focal lengths Zeiss produces Otus lenses. That several primes will be produced is not in doubt (rumours abound of a wide and short tele). However, I would be very interested to learn if they intend to produce a zoom(s) of (near) comparable quality. Unfortunately a zoom, if it is ever released, would be announced only after the majority of primes in order to capitalise on sales of the latter.
In producing a zoom in addition to primes, Zeiss would in essence duplicate the Leica S system (the Zeiss 55mm all but equals the Leica S 70mm in performance), albeit without autofocus or central shutter lenses.
