Nikon does not work as a DK-19. Hoodman makes a real eyecup for the Z9, BH #HOHNZ9 MFR #HNZ9 . BH description is not correct; the Hoodman Z9 eyecup does *NOT* interfere with the swing/articulate action of the rear LCD screen (monitor) on a Z9. Note that the Hoodman has better construction than the Nikon -- my DK-33 had a mechanical failure as the front and back plastic rings of the DK-33 are held together by three small plastic "struts" -- one of mine cracked. Nikon would only honor the warranty if I sent in the entire Z9 body for "repair", and instead instructed me to order another DK-33 from regular retail suppliers (BH is such a supplier).

If you come to B&H Chat, you can have a video chat with a photo specialist at the B&H store who can show you exactly how to install this.

The Nikon DK-33 Rubber Eyecup is compatible with the Nikon Zf Mirrorless Camera.

The Nikon DK-33 Rubber Eyecup is complete and ready to install on the Z9 camera.

The Nikon DK-33 Rubber Eyecup will not fit the Nikon Z6. You could get the Hoodman HoodEYE Eyecup for Nikon Z6 and Z7 Models. Here is the link: https://bhpho.to/3qvX00x
