Hi,only supports manual focusing.If you need the AF model,please choose KF06.466  

Could you please update us your full Minolta lens model ?as Minolta has MD MC and AF mount, K&F Concept MD-M4/3 is suitable for: Lens: Minolta MD MC Mount lens(not for Minolta AF mount: KF06.157) Camera: Micro 4/3 (MFT) mount mirrorless camera like Olympus PEN, OM-D series, Panasonic Lumix DMC-G1, G2, G3, G10, GX1, GH1, GH2, GF1, GF2, GF3, GF5, GH4, Panasonic AG-AF100 Mirrorless Digital Cameras, Black Magic Pocket Cinema Camera (BMPCC) 

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

Focus peaking is controlled by the camera, not the adapter. You need to check your individual camera. My Panasonic G6 does have focus peaking active with this adapter and other adapters also. 

It will work with all nikon lenses. The ai-s and D lenses are easiest as you can set the adapter to the largest aperature and then use the aperature ring on the lens to fine tune. With the G lensyou have rudimentary control over aperature with the adapter. Think there are only 4 or 5 settings on the adapter.
