Automatic Extension Tube Set (Macro)

 

Automatic Extension Tube Set is combined of 3 metal rings.
Equipped with electronic contacts which transfer exposure data .
All automatic functions work well and there is no need to set them manually.
As for AF engine and TTL auto exposure in modern lenses there is no need to worry, it works perfectly well with extension rings.
