What you see here is the new Zeiss Otus 85mm f/1.4. And from what I heard this lens should beat the current Zeiss Otus 55mm optical performance and therefore become the best lens on market! It comes in Canon and Nikon mount and if you adapt it on a MFT camera you would get a nice 170mm fast prime lens. Or just use the Metabones Speedbooster (here at BH) and you will go back to the “original” focal length and gain 1 stop too!
Don’t know if such a lens is something for you considering the $4,000 price :(
