terminals and chop

The intermediate rings are for the money they okay Tuen what they should. If you want more counts more.
When a little time you spend accustomed mm at small shortcomings.
However, the processing is questionable clamp the rings and chop now and then.
The thread of the individual rings are not finely elaborated. I have no problem, for example the first to screw on the second ring, however klemment it if I want the first screw on the third ring.
For the money I expected something more, who wants to give it a try as it can be photographed with extension tubes without focus, it may retest with this very reasonable variente, but is quickly moving to a higher-class variant. If he has fun at macro shots
