Hi Brian
thanks for the info. That is what I thought so when I try that setting with my 10.5 cm, the lens will turn from infinity to 5 ft. It will not let me turn all the way to 4 ft. Also, when I dismount the lens, by turning back to infinity and dismounting, I noticed that the setting on the adapter is no longer at infinity but at 20. the only way I mount the lens and get the lens to focus from 4ft to infinity is to set the the adapter to 3ft, set the lens to somewhere between 4 and 5 ft, position the lens in, play with the focus a little until I feel it click then fully mount the lens. I also can't get the lens lock to work, seems like I need to shave off a little bit on the mount for the lock to work.
Any idea? I might be be conveying the info clearly. I will try to take pictures tomorrow to show better if you can't understand me.
Thanks Brian
Vince
