This Kipon Tilt Adapter for Nikon F-Mount to Nikon Z cameras is solid and well-built. It works well. It has 360-degree free rotation with a variable tilt function up to 12 degrees.
It is useful to me for a wide variety of the smaller Nikon F-Mount lenses. Here is an example using the Nikon “O” CRT lens, and a quick sample photo. Also, a photo of the adapter and an iPhone snapshot of the Nikon CRT lens mounted on the Kipon Adapter. At about $212.00, I feel this is fair price for a tilt adapter that is well made, lightweight, doubles for the FTZ adapter, and gets a little extra angle on scores of F-mount lenses._
