The difference between solution1 and 2 is that the solution 1 use the M42 or M54 screw to connect the CFW. While solution 2 use bome M3 screw to connect with CFW. The solution 1 is easy to connect/disconnect but the camera orientation may not just be zero degree or 90 degree for the center line of the CFW. The solution 2 need to open the CFW to install the screws and it is can not to be disconnect if do not open the CFW case.
