Review on 📸 K&F Concept Lens Mount Adapter: Effortless Conversion of Contax/Yashica (C/Y) Lens to Sony Alpha NEX E-Mount Camera by Sean Maples

This is a very well built adapter, but only on the surface. It's almost perfect. However, it has a fatal flaw. My Contax Zeiss lens went into the adapter quite easily, a bit tight. Here's the fatal part. However, when I tried to install the lens adapter on my Sony A7III body, it got stuck. Like a fool I insisted and it got stronger but it never clicked. Realizing my mistake, I tried to take it off, but it got stuck. I had a terrible time getting it back. I will never use this adapter again. I will turn back.
