I must confess that I was naive when I bought my first set of C-mount adapters for my Nikon 1 V1 and Olympus OM-D E-M10. I assumed that it was very easy to make a so called “dumb adapter” – meaning an adapter that doesn’t pass through electrical signals from the camera to the lens and vice versa. Boy was I wrong! As it turns out it is quite a challenge to get the design right, in order to ensure compatibility with as many lenses as possible. At least it seems to be a challenge for manufacturers like “Kiwi”. I posted a couple of images down below, so you can identify the adapters in question.
