Hoodman is planning to release a new eyecup for Nikon Z cameras in the next 2-3 months. The new eyecup will be one of the round designs rather than the teardrop shape. This will let it be used in horizontal or vertical orientation. The eyecup will have a cutout for the eye sensor on the EVF – similar to the model they sell for the Sony mirrorless (pictured above).
A reader who handled the prototype told me that the new eyecup will work nicely. It was created using a 3D printer. The bottom of the cup is flat so it won’t block the LCD. It’s expected to have a retail price of around $20.
