Q
I bought the correct adapter, but why does this adapter not work with my camera? / What should I do when the warning 'No Lens Attached' appears?
Answer Question
A
Since it's a manual adapter , set camera "release shutter without lens" to enable when using the adapter for the first time, or the camera will fail to recognize the lens and the shutter may not be released. (Exact naming and location of this option may change depending on camera model).
