    It's a cheap way to have the capabilities of a macro lens but requires some knowledge of basic exposure and exposure adjustments when using the extension tubes.I would definitely recommend them to others wanting to explore their photography skills & look forward to working with them.

    These extension tubes work great. The trick to mount is to align the triangular arrow with the alignment mark on camera body or lens adapter (I'm using Canon Mount Adapter EF-EOS M) The white square alignment marks match up only when fully mounted. Sort of great little macro rings for the casual photographer who likes to experiment on the cheap! Decent quality for the price!
