Q: 9. Is there any way to adjust opened (or closed) size of that clamp ? I saw other brands have extra adjustment screw for fine tuning. What about this one ?

A: No there is no adjustment, I have numerous ones and have never had a problem with it becoming too lose. The clamp must be completely open to place a camera or lense in it. With the clamp half open you can only slide the lense forward or backward for balance.You want to make sure you have the stopping screws in on the lense plate or the lense/camera could fall out of the clamp when it is half open. Also, when stopping screws are in the lense plate they are the reason the clamp must be completely open so that the lense plate can be dropped in. They are the reason you can not slide the lense plate into the clamp with it only half open.
