I asked some friends if between rings at all what would suck ... I said this could order it without hesitation.
YOU WERE RIGHT!
It's cheap, in my opinion, very well made (only drawback is that sometimes when a / unscrew something "kratscht" / "schrabbt"), and does what it is!
These intermediate rings have brought me right from the beginning a lot of fun while shooting because you through this whole new theme options!
And the 115 is very well spent!
The macro carriage which is supplied here is also very good!
All in all, I forgive for the product 5 stars!
Make a must-have for all recordings which macro, but want to do without expensive lenses!
