Well done. Tested on LUMIX G85 with the following 3 lenses: NIKKOR 50mm f/1.4 without infinity focus. NIKKOR NC 24mm f/2.8. No focus at infinity. Can focus sharply over 1m. The NIKKOR-QC 200mm f/4 is the closest thing to infinity, but not quite. Good image quality near objects. All 3 lenses work great at infinity focus on a Nikon full frame camera. On the M43 Lumix G85 everything works indefinitely with an adapter. I got a stop of improvement. A small screwdriver and allen key were provided but there were no instructions as to why I would use these tools. A third-party video shows how you can bolt a central optic to the image plane for near-infinity focus. I made a big improvement after 1.5 turns. still working on it FYI, you need to loosen a small screw to allow the center optic to rotate. . I can still return it.
