Very good AF intermediate rings Meike for macros with Canon

The rings are made of plastic but very precise. Very good workmanship.
Very good fit on my 60D and good interaction with my lenses from Canon and Tamron.
The electrical functions are all given. The contacts make a stable impression.
The Entriegelungsnasen are made of metal and are pushed toward the camera body. In the form, you can be a bit misled because they mislead the press.
For the price is the top commodity. Can I recommend everyone who wants to play with macro photography.
I have just bought a second set.
Best pictures with Canon EF 40 1: 2.8 STM. Close up to 1-2cm turn to the subject.
At Tamron 100-300 1: 5 to 6.3 from my old EOS 3000 you can take the 60D approx 40-50cm turn to the subject.
I find the intermediate rings just amazing.
