Q: 1. Would this work on the Sigma 14 -24 mm f2.8 DG HSM Art lens NIKON F as well?

A: According to the manufacturer, no, the Kase Rear Lens ND Filter Kit for Sigma 14-24mm for Canon EF cannot be used with the Sigma 14-24mm f/2.8 DG HSM Art Lens for Nikon F. They did state that Kase does make rear filters for the Sigma 14-24mm f/2.8 DG HSM Art Lens for Nikon F, but they do not have them yet. The best I can state would be as the manufacturer did not provide an estimated release date for the Nikon-mount filter option for the Sigma lens, periodically check our website to see if the filter is added in the future.
