Nisi showed a Nisi 75mm f/0.95 FE prototype at Photokina 2018 this year. The lens will be available for Sony E, Canon R, Nikon Z, and L-mounts.
Nisi also recently announced a new line of prime cinema lenses.
Phillip Reeve published several sample photos and some first impressions of the Nisi 75mm f/0.95 FE prototype lens:
This lens is an early stage prototype. Housing, coatings and polishing of the elements are not comparable to the final production model. Nevertheless, we are allowed to show a few pictures to give you an opinion on the bokeh rendering of this lens. Since I am a NiSi ambassador we got an exclusive sneak peak at this lens.
The lens is quite big and heavy as is to be expected from one with these parameters. It is a short flange/mirrorless design and will be available for several mounts (including Sony FE, Canon R and Nikon Z). The prototype we saw is native E-mount and the lens covers the full frame sensor area.
Nisi products are sold at B&H Photo, Amazon, and Adorama
