hello panasonic lumix g7 is m3/4 mount, so the adapter ring could not work for panasonic lumix g7 

Yes. I use this with Nikon bellows and with Non-AI lenses. There might be isolated exceptions (exotic lenses). And, by the way, I think this is an excellent product, well made, precise, good item. 

hello Nikon-Nikon 1 fit for nikon AI/AF mount lens and nikon micro single camera body. it not fit for nikon DSLR camera ， could you pls pls let us know your lens and camera specific model? thanks 

yes, i had no problems with infinity focus with this adapter. the only FD mount lens i use anymore with my sony is a vivitar 20mm, and i pretty much only shoot infinity focus with it.
