contax g mount g1 g2 lens to leica l mount adapter – for sigma panasonic l/t sl tl typ 701 mirrorless camera

for using l mount leica / panasonic / sigma mirrorless cameras with contax g mount lenses as below:
35mm f2 planar t
45mm f2 planar t
90mm f2.8sonnar t

using this adapter, although the lens will fit physically, automatic diaphragm (ae metering), or any other functions are not retained using this adapter.
in this case the user will need to meter in “stop-down mode” since the lens does not have the ability to have its aperture controlled by the camera body.
