Techart Pro LM-EA7 Adapter(Techart) is an amazing product that allows vintage lenses supporting auto-focus in Song a7ii series. However, its structure is not strong enough when "heavy" SLR lens are adapted on it. The Lens will tilt downward by gravity and you will hard to get a sharp image. Also, the weak structure affects the focusing stability and accuracy.
This creation has the following objectives:
improve stability for heavy lens (Techart + Nikon adapter)
provide a more tidy outlook by covering the adapters
provide a flat bottom surface so that the camera can be sit on table properly
I may try to improve in future:
add bearing between the moving adapter and support
add screw holes on bracket to match the 2 screw on Techart
