FLO were kind enough to assist me with my first camera back focus measurements and this item was on the list of needed items. It works very well indeed. Easy to set and locks solid. The only thing I did was to add a tiny spray of WD40 to the threads. But only a hint of oil !!
Great item.

I already had the 29mm version of this adapter but since changing my setup I needed something that would cover exactly 37mm spacing for my field flattener.
This done the job perfectly and completely hassle free. I screwed it down to 37mm and connected to my field flattener and camera. After double checking with a set of digital calipers it was bang on and hasn't moved since.
Well made, solid and the locking ring is a very nice touch to keep everything in place.

Well made and easy to setup. Once the length is set the locking ring makes the whole assembly rigid
