"Great macro extension tube!"5.0 starson by Bibbybobbybooby
Pros: Small & lightweight.
Solid build, connects to camera body with no slop.
Cons: None at all.
Summary: As with the Canon EF 25mm II extension tube, this 12mm tube will provide your CURRENT Canon lens with new life. You can use it to get close and personal on small objects and focus in ways you never thought possible. Buy both tubes and combine them for even more precise work!
