Kirk L-Bracket for Nikon Z6/Z7 brand_Gralab dispensing with the multiple helicoids

dispensing with the multiple helicoids of a unit focusing lens for a single moving front element that kind of partially unscrews to focus

it’s because this lens has some lightly radioactive glass elements

but it's usable on any standard hot or cold shoe (without parallax adjustment)

Clean glass with minor dust
