I just bought a Laowa 15mm f/4 1:1 macro lens with a plain Nikon F mount. It doesn't do any kind of electronic or mechanical communication with the camera, it just focuses light. One thing that has always bothered me about wide angle lenses is that they don't focus close enough - I have screw in close up lenses and extension tubes, but they never seem to be in my pocket when I'm shooting. With this lens I can focus as close as I want, all the way down to 1:1. That's about half an inch from the front element though, so you need to be VERY creative to get light to your subject. Half life size (1:2) though is about 5 inches away, so you can get real close without any specialized lighting equipment.
Here's a toy admiring the Christmas tree it's under, shot with this lens a couple inches from Thomas's face:
