I have read the review.
The lens looks very impressive. The 70-80% MTF for fine structures (40 lp/mm). Very high contrast and saturation. Almost no CA, very nice bokeh and low distortion which is unusually in a 15mm.
Looks very impressive. Should perform well on the new generation of Canon/Nikons.
I have noticed on the last few Zeiss lenses released they have upped the performance and the price.
I am in the market for an ultra wide. Perhaps this or the Canon 17tse.
