A member on getdpi, claims with the newest kipon adapter, that the contax g biogon 21mm fits without trimming, i will be getting mine hopefully next week to try
Unless that new Kipon adapter moves the lens back away from camera body (and affecting infinity focus), it's not going to work. Here is a picture of my G 21mm Biogon on a NEX adapter. You can clearly see that the plastic shields extend past the the end of the adapter.
I tried to fit it to my NEX-5. These shields hit the built up flat areas to the top and bottom of the sensor (I know this becuase they left marks there as I tried to mount the lens). For it to fit, you clearly need to trim these shields. The adapter, if the proper lens registration distance is used, has nothing to do with with this. The adapter is not prohibiting the use of the lens.
